What types of entrance doors are there? Repair and adjustment of metal entrance doors. installation of a metal entrance door

To reliably protect your home from thieves, as well as to ensure high heat and sound insulation characteristics of your home, the most reliable and effective solution are metal entrance doors. If the owner is not satisfied appearance steel door, there are many options for its internal and exterior finishing, so this design will fit perfectly into any interior. The modern market offers big choice metal doors, but if you have the desire and opportunity, then it’s easy to make them yourself.

Types and designs of metal entrance doors

In order to choose the right metal front door, first you need to know where it will be installed: at the entrance from the street or in the entrance. In addition, you need to decide on the requirements that you place on it: high heat and sound insulation characteristics, fire safety, large width, etc.

There are different types of entrance doors: street, fireproof, with glass, driveway and others

One of the main advantages of metal entrance doors is their high strength. There is a large selection of different finishing materials that are used to decorate a metal door from the inside and outside, so it will look aesthetically pleasing in any room. Availability anti-corrosion coating allows you to increase the service life of such a structure and protects the surface from the negative effects of external factors.

The strength and reliability of metal doors depends on the thickness of the metal used for their manufacture. In the cheapest models it is 0.5 mm, and in more expensive and high-quality models it is up to 3 mm. To improve the performance characteristics of the doors, the inside is filled with heat and sound insulating materials. Various natural and artificial materials, for example, wood, veneer, decorative film, MDF overlays, etc.

Entrance doors to a private house

At first glance, street entrance doors to a private house are no different from those installed in apartments, but this is not so. Exterior door at the same time it should not only protect the house from unauthorized entry, but also be its decoration, since it is constantly in sight.

When choosing a street door to your home, you need to consider the following factors.

1. Wear resistance and resistance to mechanical damage. Such structures must have an anti-vandal coating in order to provide reliable protection for the home for many years.
2. Heat and sound insulation. Entrance doors are a barrier between the street and the house, so their design must necessarily have a double-circuit seal and a thick layer of heat-insulating material.
3. Fire resistance. An important characteristic, since metal street doors must provide high security and practicality.
4. Burglary resistance. Since doors ensure the safety of the residents of the house and the safety of property, the degree of their resistance to burglary should be very high. There are three burglary resistance classes for metal doors:
   • I class - a budget option, which is not suitable for installation from the street side, since such doors can be opened using hand tools;
   • Class II is the most popular option, which is characterized by high reliability and affordable cost;
   • III class is the most reliable doors which are made of thick sheet steel, they have additional insulation, therefore they are an ideal option for installation on the street side. To open such a structure, attackers will have to work with a powerful grinder for 15 to 30 minutes, and as a rule, they do not have this time.
5. Appearance. Since the street door is in plain sight, it must match the architectural design of the building. There are many finishing options, so such a design can always fit organically into both the interior and external design Houses.

Street entrance doors must fit into decoration Houses

If you install ordinary metal doors at the entrance from the street without insulation or with a minimal layer of insulation, then such a structure will freeze. Frost and ice will appear on its inner surface, which will significantly reduce the thermal insulation performance of the house. In addition, such a door will not be able to protect the house from the sound of the street, so it will be uncomfortable and uncomfortable to be in it.

Entrance doors to the apartment

For installation in an apartment, the safest and most reliable are swing metal doors that open outward. This solution not only prevents the door from being knocked down, but also saves space in the hallway when exiting and entering the room.

Most often, single-leaf doors are installed in an apartment, but if possible, you can also install a one-and-a-half-leaf structure. In this case, one part of the canvas has standard sizes, and the second bar opens when it is necessary to bring in or take out large-sized furniture or in other similar cases. For an entrance door, it is not recommended that the leaf width exceed 100 cm - if wider is needed, then it is better to install a double-leaf structure.

Most often, single-leaf metal doors that open outward are installed in apartments.

When choosing metal entrance doors to an apartment, you need to pay attention to the following characteristics.

If it is necessary to register in a house or apartment doorway width more than 1 m, then it is best to install a double-leaf metal door. Typically this solution is used in public buildings, where there is a large flow of people, but it can also be implemented in a private house or apartment.

Now there is a large selection of double-leaf entrance doors metal structures, which are characterized by high reliability, strength and durability. The cost of such a door is influenced by the thickness of the metal, the type and thickness of insulation, the presence of a reinforced frame and the type of lock used.

When choosing a double-leaf door, you must take into account the location of its installation, whether it will be the entrance to Vacation home or to the apartment. Street structures in addition to a beautiful appearance and resistance to burglary, they must be adapted to moisture, sunlight and other unfavorable natural factors.

Double-leaf entrance doors differ in several ways.

1. Sash width. There are two options: both doors have the same width or one door is narrower than the other. Typically, one half of the door constantly performs its functions, and the second opens as needed.
2. Size. Standard width valves are a multiple of 10 cm and are usually in the range of 40–100 cm. Combination of valves different widths allows you to issue any doorway.
3. Opening the doors. It can be done both inward and outward, while each leaf can open only in one direction.

A double-leaf metal entrance door has a number of advantages:

• you can bring in and take out large furniture or other items;
• it is possible to design a doorway of non-standard size;
• provides a beautiful appearance.

The only drawback of this solution is the high cost.

Entrance doors with glass

Metal entrance doors with glass are an excellent option for a private home. They provide reliable protection and at the same time look very stylish and allow additional sunlight into the house.

Metal doors with glass have replaced all-metal doors. Despite their apparent fragility, they are highly durable and reliable, so they can protect your home from uninvited guests, cold and street noise.

For their manufacture, special impact-resistant glass is used, and the metal part of the structure is no different from ordinary entrance doors. Often such doors are complemented with decorative forging, and instead ordinary glass use stained glass. Forged elements not only make it possible to create exclusive and unique canvases, but also act as additional stiffening ribs. To protect from prying eyes, you can cover the glass with a mirror film.

Glass inserts are highly durable, and the presence of forged elements ensures additional protection from intruders

The disadvantage of metal doors with glass is their higher cost, but they have many advantages:

• high thermal insulation characteristics;
• high strength and reliability;
• the ability to fill the house with additional natural light;
• attractive and unique appearance.

Such designs are premium products, and therefore have a high level of safety and quality, as well as a long service life.

Fireproof metal doors

Modern metal fire-resistant entrance doors allow you to protect your apartment from fire that occurs in the entrance.

Such designs can have different external finishes, so they fit perfectly into any interior.

The main requirement for such a door is fire resistance. When purchasing it, you must definitely pay attention to this indicator, which is designated as EI in the product passport. The number next to the letter designation indicates how long the door can withstand fire, that is, if the marking is EI-60, then the fire resistance of the door is 60 minutes.

Fire doors must withstand direct exposure to fire for at least 30 minutes The fire resistance of this design is ensured not only by the thickness of the metal sheets, but also canvases. In addition, the door frame also has a special design, which should ensure reliable fixation of the door leaf.

You can buy a ready-made fireproof metal door, or you can order it to be manufactured according to an individual plan and with specified characteristics.

A door is considered fireproof if it has a resistance level of at least EI-30, that is, it can withstand fire for 30 minutes, but it is best to give preference to designs with EI-60 or EI-90.

Metal entrance doors

In most apartment buildings, metal entrance doors have recently been installed. This solution not only protects the entrance from the penetration of cold, but also prevents thieves, drug addicts, hooligans and other disadvantaged categories of citizens from entering there. Access doors in apartment house, just like street doors to a private house, must be strong and reliable. Their difference is that fewer requirements are imposed on appearance, and they may not have at all or have an insignificant layer of thermal insulation.

When choosing access doors, you need to pay attention to the following characteristics:

• the presence of a closer is important element, which will not allow the door leaf to close abruptly, so there will be no extraneous noise;
• the presence of a combination lock or intercom allows only residents of the house or those guests you are expecting to enter the entrance;
• trouble-free operation - since access doors are used very often, they must function flawlessly for a long time, therefore special attention is paid to the quality of the hinges;
• high-quality external coating, usually powder paint is used, which is highly resistant to atmospheric precipitation, sun rays and perfectly withstands temperature changes.

Entrance doors must have strong hinges to withstand a large number of openings and closings

Since the entrance door to an apartment building must have high strength and reliability, metal sheets with a thickness of at least 2 mm are usually used for its manufacture.

If the entrance is not heated, then you should not worry much about insulating the door. The main task of this design is to keep moisture out and protect from drafts, which is why it is equipped with high-quality seals.

Entrance doors with hidden hinges

In addition to the fact that the hinges provide opening and closing of the canvas, they are also elements of anti-vandal protection. Let's consider whether hidden loops really have advantages over regular ones.

1. Unlike ordinary hinges, it is impossible to cut off hidden hinges when the doors are closed. But you need to know that almost all entrance doors additionally have anti-removal elements, so even without hinges it will not be possible to pull them out of the frame. In addition, it must be taken into account that cutting off the hinges will take time, and a lot of noise will be created, so it is unlikely that such a solution will be implemented in the entrance. It is much easier to break into a house by picking a lock.
2. Beautiful looking door. This is also a controversial advantage, since some people like it when the hinges are not visible, while others prefer traditional solutions.

The presence of hidden hinges increases the burglary resistance of doors and provides a more attractive appearance

Hidden hinges also have serious disadvantages:

• they do not allow the door leaf to be fully opened, the maximum angle is no more than 130 degrees, which often makes it difficult to move furniture and other large items;
• the cost of such canopies is significantly higher than conventional ones;
• they are not so strong and under high loads they sag more, so you need to be sure of the quality of the hinges, otherwise there may come a time when it will be difficult to get into the apartment;
• there are restrictions on the size of the door leaf, it should be no more than 2100x980 mm;
• only one sealing circuit can be installed, which negatively affects the sound insulation of the doors;
• It becomes more difficult to remove the canvas from the box.

Three-circuit entrance doors

The thermal insulation characteristics of the door are especially important when installed in a private house, since there it is in direct contact with the street. To ensure improved thermal and sound insulation characteristics of the house, there is a solution such as three-circuit metal doors. They not only have high thermal insulation properties, but also provide excellent protection from street noise.

Two of the three contours are on the canvas, and one is on the door frame, which ensures their maximum fit to each other. When creating a three-circuit door, additional stiffening ribs are usually installed. This solution allows you to increase the thickness of the door, so you can lay a thicker layer of insulation and install more reliable locks.

The presence of three sealing circuits increases the heat and sound insulation qualities of metal doors

A three-circuit metal door is usually installed at the entrance to a house from the street when people live in it permanently, so it needs high-quality thermal insulation.

In addition, such structures can be installed in apartments located on the first floors of apartment buildings and at the entrance to heated entrances.

• The main advantages of three-circuit metal doors:
• high heat and sound insulation characteristics;
• protection of the premises from the penetration of foreign odors and smoke during a fire in the entrance;

high class of burglary resistance. When choosing an entrance door, many owners pay attention to its soundproofing characteristics. This indicator is important for both doors in a private house and in an apartment. It's not very pleasant to hear how staircase

Children are running around or in the morning a neighbor takes the dog for a walk. To improve the comfort and coziness in your home, it is enough to install metal doors with sound insulation, which are also called acoustic doors.

A soundproofed metal door provides a more comfortable stay, because you can’t hear any extraneous noise from the street or the stairs behind it.

• Such designs have the following features:
• due to the use of additional filling, the weight of the door will be greater;
• to fill them, basalt wool is usually used and two layers of a sound-absorbing membrane are installed;
• a layer of cork is placed between the metal sheet and the finishing MDF panel, which acts as a thermal break; a special pattern is milled onto the finishing MDF panel, which allows cutting sound wave
• to many small reflections, after which the sound strength decreases significantly;

4 contours of sound-absorbing seal are used.

The popularity of metal doors with sound insulation is constantly growing, this is explained by the fact that they protect the house well from external noise, have high burglary resistance and a beautiful appearance.

Dimensions of metal entrance doors

There is a state standard that determines the size of entrance doors. Their main parameters should be as follows.

The standard width of the entrance door is larger than that of the interior door, this is necessary to ensure the free movement of people and large cargo. Gradually, standards are becoming a thing of the past, as houses and apartments often have original design solutions , so doors are required. This is especially true in private construction. Although doors can be made to order, experts recommend that their width be between 90–200 cm and their height between 200–240 cm.

Manufacturing of metal entrance doors

You can purchase a ready-made metal door in a store, but if you have the desire, capabilities and certain skills, you can make it yourself. This solution allows you to create a door to suit your dimensions and requirements, as well as save money.

To create a metal entrance door you will need materials and tools:

• a metal corner or profile to create the frame of the door leaf and door frame;
• steel sheets 2 mm thick;
• at least two, and if the weight of the fabric is large, then 3–4 loops;
• accessories;
• electric drill;
• Bulgarian;
• welding machine;
• construction foam;
• fastening elements;
• cladding material;
• sealing materials;
• insulation.

To make metal doors you will need specialized tools that can be rented

Much will depend on where exactly the metal door will be installed. If at the entrance, then only one sheet of metal is enough. To install at the entrance to an apartment or house, you will need two sheets, between which insulation is placed.

When creating an entrance door, the work is carried out in several stages:

• making a door frame. There should be 2 cm on each side between the frame and the doorway;
• door leaf assembly. There should be a gap between the canvas and the box, and the sheet should protrude slightly beyond the edges of the frame;
• installation of accessories;
• insulation of the structure;
• finishing of the finished product.

The metal sheet must be welded with several seams no more than 4 cm long, located at a distance of no more than 20 cm from each other.

The sequence for making a metal entrance door yourself will be as follows.

1. Taking measurements of the door frame. It is necessary to leave a gap of 2 cm between door frame and a frame, which after installing the doors is filled with polyurethane foam.

   Before you start creating doors, you need to correctly measure the doorway

2. Cutting a profile or corner 50x25 mm. The resulting parts are laid out in a rectangle on the welding table. Be sure to check the diagonals, which must be equal. After this, the door frame is welded.

   The frame of the frame and door leaf can be made from a profile or corner

3. Taking measurements of the door leaf. To do this, measure the finished box and take into account the 1 cm gap that should be between it and the canvas.

   The size of the door leaf should be 1 cm smaller than the frame to ensure normal opening of the door

4. Cutting a profile or corner 40x25 mm to create a frame for the door leaf.
5. Installation of loop profile. Before this, the location of the hinges is precisely determined to ensure normal opening of the door. The upper part of the hinge is welded to the door leaf, and the lower part to the frame.

   The hinge is welded to the frame, after which the hinge profile of the door leaf is fixed to it

6. Checking the parallelism of the profile of the canvas and the box. After all parts of the canvas frame are aligned, they are welded to each other.

   The remaining frame elements are welded to the loop profile of the canvas

7. Laying a sheet of metal on the canvas. It is necessary to leave 10 mm of sheet on each side of the canvas for the catch. The sheet is first welded near the hinges, and then along the perimeter of the canvas.

   The metal sheet is placed on the frame of the door leaf and welded

8. Installation of the cover strip. It is welded on the inside of the canvas. To strengthen the canvas, you can weld several stiffeners.
9. Cleaning welds and painting the door.
10. Lock installation. A slot is made under it in the end strip of the canvas.

    A slot is made in the end strip of the door leaf to install a lock

11. Sheathing installation. This could be film, wood panels, leatherette, etc.

    The covering of a metal door can be made of clapboard, solid wood, veneer or other materials

12. Insulation of the canvas. First, insulation is laid on the sheet, and then everything is covered with another sheet of metal.

    If necessary, the metal door is insulated

Installation of metal entrance doors

If you were able to make metal doors yourself, then there will definitely be no problems with their installation. The installation process of such a structure is not complicated - you just need to follow the recommendations of specialists.

1. Preparation doorway. This stage consists of adjusting the dimensions of the doorway to standard ones. To do this, the remains of the old plaster are removed if there were other doors in this place before. The gap between the frame and the opening should be 1.5–2 cm. This will allow the door frame to be properly aligned.

   The doorway is cleared of mortar and plaster residues

2. Door installation. If possible, it is better to remove the canvas, but installation can be done this way. The box is inserted into the prepared opening, while the canvas is opened 90 o and fixed with a support.

   If possible, remove the canvas from its hinges, but you can install the box together with the canvas

3. Leveling the door frame. Using wooden wedges, the box is aligned vertically and horizontally.

   The correct installation of the door is checked using a building level

4. Fixing the box in the doorway. It is secured using anchors through special eyes. First, do not tighten the anchors all the way, check again for correct installation, and then tighten everything well.

   The box is fixed using special anchors

5. Performance monitoring. Check how easily the door closes and opens. If necessary, adjust its position.
6. Sealing the gap between the wall and the box. For this purpose it is used polyurethane foam. The gap between the threshold and the box is filled with cement mortar.

   After installing the door, the gaps between the frame and the wall are filled with foam.

In order for the foam to completely harden, after applying it it is better not to use the door for six hours.

Accessories for entrance doors

In order for a metal entrance door to be truly reliable protection for your home, it must be equipped with high-quality fittings.

The following components are usually used for metal entrance doors.

1. Pens. They can be steel, aluminum, copper, silumin or alloys. The shape can be either rectangular or curved; various coatings are used to protect the metal, but most often it is chrome or nickel. Handles are:
   
2. Loops. Depending on the weight of the door there may be two or three hinges. They are of the following types:
   
3. Closers. This device ensures smooth closing and opening of the door. When choosing a closer, you need to take into account the weight of the door, as well as its operating conditions, since not all of them can withstand temperature changes.

   Door closers are selected taking into account the weight of the door and its operating conditions.

4. Pads for locks. They are armor plates that protect the lock from being hacked. Mortise overlays are located inside the canvas, they are invisible and cannot be removed.

   Armor plates on the lock can be mortise or overhead

5. Peephole. These devices may have different angle review. The minimum is 120°, and the maximum is 180°. The body of the eye can be metal or plastic, and the optics can be glass or plastic.

   Lately the eyes have been crowded out modern systems CCTV

6. Locks. They can be overhead or mortise. There are several types of locks:
   • cylindrical - although it is quite difficult to open it with a master key, the cylinder can be drilled, so the installation of an armored lining is required;
   • deadbolt - such a lock has high strength, but choosing a key for it is quite simple, so it is better to use it as an addition to the main lock;
   • level - universal solution, providing high level security, the lock is locked by combining the plates, of which there must be at least 6 pieces;
   • electronic - highly reliable, but due to high cost is not very popular yet.

   Locks for entrance doors are mechanical, electromechanical or electromagnetic

Repair and adjustment of metal entrance doors

Despite the high strength and reliability of metal entrance doors, after some time there is a need for their adjustment or repair.

Main causes of failure:

• damage to the door leaf by corrosion;
• the canvas is distorted, this malfunction is eliminated by adjusting the hinges;
• loose fit of the canvas due to wear of the seal;
• jamming or breakage of the lock.

How to resolve the problem depends on the cause.

1. The lock is broken. Ordinary door lock without repair, it can withstand from 7 to 15 thousand opening and closing processes. Often, owners do not lubricate the lock during the entire period of operation, which can lead to breakdown after 5–7 years. Depending on the type of lock, repairs are performed as follows:
   

   If the hinges are secured with screws, then with their help you can slightly change the position of the door leaf

2. Damage to seals. After some time, it is necessary to replace the sealing elements.

   If the need arises, the old seals are removed and new ones are attached in their place.

3. Damage to the coating. After some time, the protective coating of metal doors may become damaged, which leads to corrosion of the door leaf and frame. In this case, the repair consists of updating the coating. The surface should be thoroughly cleaned, the fittings should be removed and the doors should be painted with anti-corrosion paint; this should be done in 2–4 layers.

   Recovery paint coating doors are cleaned, degreased, primed and painted in several layers

4. Damage to the casing. If the doors are trimmed with artificial or natural leather, then if it is damaged, the trim will have to be completely replaced. Powder coating cannot be restored at home, so the doors must be taken to a specialized workshop.

If the hinges are standard and they are welded, then adjustment can be made by installing additional washers, with the help of which the door leaf is raised. If the hinges are secured with screws, then you need to loosen the screws and move the blade slightly in the desired direction, and then tighten everything again.

Welcome home! The first thing we see when we appear on the threshold of our home and the first thing that catches the eye of our guests is the front door. - an important part of the interior and we, of course, would like it to fit organically into the style we have chosen. In addition, do not forget that the main task front door - to protect our homes. Therefore, it is worth taking care not only of the appearance, but also of the reliability of the door and its durability. The reliability of a door is determined by the level of protection against brute force and intelligent burglary, the possibility of external surveillance, as well as the quality of thermal insulation and sound insulation.

When choosing an entrance door, you should pay attention to the expected intensity of its use, the size of the doorway and the direction of opening the door, the design of the frame, as well as the quality of the door leaf and hinges. It is important to pay special attention to anti-burglary elements and the choice of locks. Monitor the level of toxicity and flammability of the door filler.

Even taking into account all these nuances, achieving your goal, namely finding a high-quality, reliable and pleasing to the eye door will not be difficult. Today there are a huge number of different types doors, the features of which will satisfy the most demanding buyer.

And here we come to the question of the article: what types of entrance doors are there? Homify specialists will help us understand this issue.

Types of entrance doors by material of manufacture

Depending on the material of manufacture, metal, wood, plastic and glass doors. The most popular among users are metal, mainly steel doors. Steel doors are considered the most reliable. Although, to begin with, it should be mentioned that there are no doors that are absolutely impregnable for burglars, because they closely monitor new developments and constantly improve their skills. However, the more time it takes to break into a door, the less likely it is that a thief will take risks and fiddle with an impenetrable door for a long time, because every extra second means an additional risk of being noticed.

So, back to steel doors. In this case, a fairly simple rule works: the thicker steel sheet, it is stronger and, accordingly, more reliable. The thickness of the steel sheet must be at least one and a half millimeters. In addition, the number of stiffeners affects the strength of the door. In this case, the most reliable design is one in which vertical stiffening ribs complement horizontal or inclined ones.

In addition to metal doors, wooden doors containing a metal sheet or frame inside are very popular. They are quite durable and, moreover, wooden doors often look more advantageous than steel ones. Oak doors made of solid wood, are also very durable, but such doors will cost you a lot.

Aluminum doors, especially sliding ones, are often used in garages, as well as in outbuildings. Plastic and glass doors can be very decorative, but they are not particularly suitable for our reality and are more common in the form of interior doors.

​Types of entrance doors by purpose

According to the intended purpose, they are allocated following types entrance doors:

shockproof;

bulletproof;

fire protection;

sealed;

soundproof.

At the same time, we can reassure you a little: any entrance door with more or less high strength indicators is shockproof. Bulletproof and fireproof entrance doors are made from high-strength alloys and often pass additional processing. These doors are the most reliable. Soundproof doors are quite expensive and are extremely rare in private homes. Sealed entrance doors are not used at all in private construction.

Types of entrance doors by opening method

Your front door can be hinged or sliding. Hinged doors differ in location (left or right) and opening direction (inward or outward). Sliding ones differ in the opening direction (left or right). It should be remembered that an entrance door opening outwards creates less loss warmer than a door that opens inward. In addition, such a door is also safer. Sliding doors are very rare in private homes due to the complexity of production and installation. However, this type of door is often found inside a space, although it is recommended to design such structures in advance before construction begins.

It can be added that there are several types of entrance doors depending on the number of leaves. Doors are single-leaf, that is, they have one door leaf; one-and-a-half doors, which have two doors, but one of them opens in rare cases to increase the doorway; bi-leaf, having two doors. Double doors often look very solid and even massive, depending on the material chosen.

Types of entrance doors by appearance

The shape and appearance of your front door play an important role. Therefore, in addition to strength, it is worth paying attention to the aesthetic characteristics of the door. Depending on the shape of the door, there are standard rectangular, classic doors in the form of an arch (the top of the door has the shape of a semicircle) or arched doors with a blind transom, in which the top of the door (arch) does not open, and the door itself has a rectangular shape. This technique is used to avoid making the door heavier when the opening is high. In addition to all of the above, entrance doors come with glass inserts and other decorative elements. At the same time, armored glass is not used in the entrance doors. Decorative elements– carvings, an unusual peephole, painting, an original handle or door knocker give the door individuality.

Safety first

It is important to remember that in addition to the quality of the door leaf, the reliability of the door is also determined by the door hinges, which we often forget about. Door hinges There are two types - and external. Hidden hinges are preferable to external ones, since their design is hidden and they cannot be cut off, because this is how burglars often enter an apartment if they do not want to bother with a complex lock. But if your door is equipped with anti-removal pins, then it doesn’t really matter which hinges: such a door cannot be opened even by cutting off the hinges.

Reliable lock

Of course, we must not forget about the castle. Depending on the type of fastening, locks can be carved or overhead. However, there are several types of locks that are designed for different types of materials. Often, manufacturing companies offer a specially designed lock for each door model, emphasizing that universal locks are often not so reliable.

Experts often recommend installing at least two locks different designs(for example, one suval and one cylinder lock). This way you can protect yourself from two types of robbers - those who use brute force and intellectuals. Modern cylinder locks are so complex that finding a master key for them is almost an impossible task. Two different locks will complement each other, thus reducing the chances of break-ins. As an alternative, you can choose one lock that combines these qualities. In addition, there are two- or three-cylinder locks on the market that can be opened with several keys.

The so-called smartlocks - electronic locks with digital encoding or scanning they are not inferior in reliability. Their only drawback is their dependence on power supply. But even in the absence of electricity, such a lock will work for another two days, and after that it can be used as a regular lock thanks to reliable internal latches.

The main task of a steel entrance door is reliable protection of the room. However, the importance of its aesthetic qualities cannot be denied. How to correlate all the necessary parameters and choose from a variety of options the door that is right for you?

Let's find out together what the steel door market offers and what to look for when choosing this product.

Types of steel doors

At the first stage of selection, you need to decide in which room the structure will be installed, what its purpose is and what requirements are imposed on the degree of its resistance to burglary.

Classification by purpose of doors

There are several types of doors depending on the purpose of their use. It's quite easy to decide here.

Armored(bulletproof). Such steel entrance doors were originally intended for banking institutions and other premises requiring increased protection. Currently, they are widely used in residential premises, providing maximum protection against unauthorized entry. Armored doors are made from steel sheets with a thickness of 5 mm or more and are equipped with powerful horizontal and vertical stiffening ribs (and in some cases, an additional metal sheet or numerous armor plates are installed inside the structure).

Fire protection. They are often installed in apartments adjacent to non-residential premises(hairdressers, shops), in elevator halls, waste collection chambers, electrical switchboards and technical rooms, as well as at emergency exits. Such products provide room protection from fire and toxic combustion products for one hour or more. The doors are made of steel sheets with a thickness of at least 2 mm and are equipped with insulation from non-combustible materials, heat-resistant and non-toxic seals. Anti-panic system locks are used, which are opened from the outside with a key, and from the inside by pushing the door or pressing the handle.

Tambour. They are installed on the landing and cover the entrance to several apartments at once. They provide protection from unauthorized entry, cold, dirt and extraneous sounds. Characterized by simplicity of design, minimal finishing and are equipped with deadbolt locks.

Technical. These products provide reliable protection technical premises, cash registers, basements, utility blocks, switchboards, entrances, warehouses, industrial and commercial buildings. They are equipped with modern locks of high burglary resistance classes. In their production, the main focus is on functionality, and appearance fades into the background.

Classic. Such doors are installed much more often than others in apartments, private houses, and dachas. The products are distinguished by the breadth of their design, the use of steel sheets 1.5–2.5 cm thick in the construction, and a number of other features, which we will discuss in detail below.

So, having decided on the appropriate type of design, you can begin to search for a specific product.

Burglary resistance classes of steel doors

There is the following classification door designs depending on their ability to resist hacking:

Class 1. Such products must be resistant to brute physical force (kicks, shoulder strikes) and simple tools: a pry bar, a lever with attachments, a nail puller, a crowbar, etc. To gain partial access to the room, an attacker will need at least 5 minutes, and for full access - at least 9 minutes.

Class 2. Similar designs are able to withstand household hand tools - axe, hammer, sledgehammer, chisel, etc. The time required to gain access to the room is 9–16 minutes. Most often, these products are installed in residential buildings.

Class 3. These are durable steel doors that cannot be broken using hand or electric household tools. It will take burglars 16–23 minutes to enter the premises.

Class 4. This level is assigned to bulletproof products. Hacking time is at least 23–35 minutes.

The burglary resistance class largely depends on design features doors

Steel door structures

When choosing a door, you must take into account the purpose of the room. Standard single-leaf products are the most common design, which provides the most reliable protection, since it has a minimum of moving elements.

IN warehouses, workshops, entrances and places with a large flow of people are often installed bivalve doors (symmetrical - with leaves of the same width, or asymmetrical). They fill a large opening necessary for moving large loads and passing significant human flows. At the same time, the burglary resistance of such products is lower than that of their single-leaf counterparts.

Single or double leaf arched The designs have a stylish and unusual appearance. Products with transoms used in rooms with non-standard openings.

The best material for making entrance doors is cold-rolled steel. Sheets of this material are characterized by increased ductility, ease of processing and corrosion resistance.

Seals

Rubber, polyethylene foam, foam rubber, silicone or plastic seals are installed in places where the door leaves come into contact with the frame and provide not only additional sound insulation, but also prevent the passage of foreign odors or the formation of drafts. The most popular are magnetic rubber seals. Foam rubber is an outdated option that is practically not used in modern doors.

Fillers

For high-quality steel doors, the space between the steel sheets is filled with materials that provide heat and sound insulation, and protection from moisture. The filler must be durable and absolutely safe for family members and environment. The latest quality is possessed by: polyurethane foam, polypropylene, glass wool, fillers based on minerals, Styrofoam.

Preference for one or another type of filler is given depending on the needs and material opportunities customer. Thus, the best thermal characteristics among the materials used in the manufacture of economy class doors are polystyrene foam and mineral wool. The latter is also characterized by maximum noise insulation properties. In the production of business-class products, polyurethane foam and polypropylene foam are used, which have excellent insulating properties.

Types of steel doors by opening type

It should be remembered that, in accordance with building codes and the rules Fire safety buildings and structures" dated January 21, 1997, doors located on evacuation routes from the building must open outward. In addition, the doors of adjacent rooms should not block each other when opened at the same time.

Designs with external opening are characterized by higher burglary resistance, and their analogues with internal opening are considered the optimal solution for rooms with limited space in corridors. Increasing the level of protection for products with internal opening is facilitated by the lack of access to hinges and bolts.

Types of doors by frame type

When deciding which steel doors are better, buyers adhere to domestic traditions, according to which the product is attached to the opening of a solid frame through eyes using pins (anchors). But there are other installation techniques. Italian technology involves installing a U-shaped frame into the opening, to which the box is then attached with embedded screws. This type of box often causes concern among domestic buyers due to the lack of thresholds that increase the level of protection of the premises. That is why the so-called Russian-Italian type of box was developed,

Another installation option is an Israeli-type box. When using this technology, a crimp box is installed in the wall, and then poured with concrete. This technique is not applicable in domestic conditions, since it involves building a wall around the box, rather than installing the structure into the wall.

Decorative panels

The cladding allows you to give the door a stylish appearance that harmoniously complements the interior. Popular today decorative panels, which are installed on the internal and external surfaces of the product. These are, first of all, inserts made of solid wood, natural or artificial veneer, fiber parallel (a sandwich of several layers of moisture-resistant marine plywood bonded with vinyl glue), wear-resistant vinyl plastic and other materials. Popular designs with mirror surface, as well as with stylish glass and aluminum inserts. External panels VIP doors are most often made of leather, wood and even semi-precious stones, premium panels are made of combined materials(polished metal, glass), high-quality MDF, mid-price panels - laminate, vinyl plastic, thinner and inexpensive MDF.

Manufacturers

The rating of steel doors is top domestic producers, such as ESTA, Guardian, Elbor, Arsenal Service Steel, Bastion, BelKa, Columbus, Jaguar-M, Gerda, Optima, etc. Foreign products occupy only 10% of the market. The number of foreign companies offering their goods to Russian buyers includes Belarusian manufacturers “Doors of Belarus”, “Steel Line”, “ Iron house", "Business Metal", Italian Dierre, Albertin, GARDESA, Lediva, Panto, Israeli MAGEN BARIAH, Finnish ALAVUS, etc.

Prices for steel doors

Prices are determined primarily by the quality of the materials used and production technologies.

Economy The lower price range is products priced at 12,000–30,000 rubles. They are manufactured using modern technologies, but their production involves the use of thin steel (1 mm or less), simple stiffeners, a 1st class security lock, and cheap fittings and finishing. Sometimes such products lack insulation.

Business. The price of steel doors in this category is 30,000–60,000 rubles. Such products comply with GOST, consist of two solid-bent steel sheets, have quality profiles and stiffeners, 3rd (and higher) burglary resistance class. Locks - not lower than 2nd class security. Most domestic and imported products fall into this category.

Premium Products costing 60,000–120,000 rubles are characterized by 3–5 classes of burglary resistance. The total thickness of the steel sheets is at least 3 mm, the product is equipped with 4th class security locks, a high level of sound insulation, hidden hinges, and additional stiffening ribs. All accessories are of high quality. For external finishing, natural veneer, fiber parallels, and combined panels are used.

Premium and business class doors are equipped with removable decorative panels that can be easily replaced in case of damage or when changing the interior or exterior.

Which steel doors are best to choose?

The quality and reliability of the door you choose will be determined by a lot of nuances. The best steel doors usually meet the following requirements:

• They are mounted either by the popular, reliable and time-tested Russian method, or by the modernized Italian method, which involves installing a four-sided frame of the main box. This technology provides increased burglary resistance of the structure and makes it possible to improve its heat and sound insulation properties.
• Have a total thickness of steel sheets of at least 3 mm.
• They are made from solid bent steel sheets, forming rigidity profiles around the perimeter of the sheets.
• They are equipped with at least two locking mechanisms: lever and cylinder.
• They have level 3 and higher resistance to burglary.
• Equipped with sound and heat insulating polystyrene filler and silicone seals.
• They have a reliable, durable and aesthetic coating with a wide range of finishing options - both in terms of design and in terms of cladding materials.
• They are equipped with hidden hinges, armored lock linings and anti-burglary pins.
• They have at least one horizontal and two vertical stiffeners.

Thus, in order to choose the right steel door, you need to consider whole line factors. A potential buyer needs to evaluate not only the appearance of the product, but also the quality of the fittings, security elements and door panels. The optimal solution for residential buildings, apartments and offices are business class products.

Entrance doors can be classified according to the following indicators and signs:
- material used in the manufacture of doors;
- purpose of the door;
- method of opening.

Types of entrance doors depending on material

Depending on the materials used in manufacturing, entrance doors can be divided into several groups:
- steel doors;
- wooden;
- aluminum;
- plastic;
- glass.

Currently, steel doors are the most common. The main material of the panel can be completely hidden finishing materials, as a result of which the structure may look like plastic or wood. This allows the product to fit into almost any interior. Most often, the finishing of a steel entrance door is done plastic panels or processing powder paints.

Powder coating is durable and practical, it is resistant to mechanical stress and abrasion. It also meets the basic safety requirements that apply to entrance doors. The percentage of its damage and abrasion during operation is 2% over 10 years. This result is ensured by a special extrusion powder coating technology. Finishing the door with plastic panels also has its advantages. The main one is the ability to replace decorative coating during the operation of the product.

It is also possible to finish the door with other materials: leatherette, lining, laminate, MDF (microwood fiber), etc.

Wooden entrance doors are used very rarely today. The main reason for the low popularity of this species is insufficient safety. Installation is advisable only in cases where they are provided additional measures security. Entrance doors made of solid oak are often used by owners of country cottages, luxury houses, and various institutions where a high level of security is provided. Of course, installing this type of door is much more expensive than installing a steel structure.

If a sliding entrance door is installed, it is preferable to use aluminum construction. They are most often used in warehouse buildings, garages, and entrances to protected areas. In the sector, this type of entrance door is rarely used, like plastic doors.

Typically plastic is used for interior decoration doors. Plastic structures can be used as entrance doors in closed protected areas. Entrance glass doors made of glass are used in private homes of wealthy customers, modern centers, as well as offices of prestigious companies. The glasses used for these purposes can be different: frosted, transparent, with a relief pattern, etc.

Purpose of entrance doors

According to their purpose, entrance doors are divided into:
- armored doors;
- burglar-resistant;
- explosion-proof;
- bulletproof;
- fire protection;
- noise-absorbing;
- sealed entrance doors.

Bulletproof doors are designed to protect people and to create a reliable barrier in the event of an armed attempt to enter the premises. This type of product is used for installation in office and residential premises. Basically, bulletproof doors are installed in safe rooms, bank branches, currency exchange offices, security posts and checkpoints.

Armored entrance doors are used to restrict unauthorized access to residential, public, industrial and auxiliary types of premises and buildings. The fireproof type of entrance doors prevents the spread of fire. This type is used for installation in rooms with sufficient big amount electrical appliances, in laboratories, chemical industry facilities and warehouses.

Sound-absorbing type of entrance doors is quite rare. It is used in laboratories, luxury residential buildings, and recording studios. Hermetic entrance doors are used for catering units, laboratories, pharmaceutical premises, operating rooms. The sealing and valves of such products must provide fire and gas resistance, and they must also withstand structural loads.

Types of entrance doors by opening method

According to the method of opening, entrance doors are divided into:
- ;
- right;
- swing;
- external;
- internal;
- sliding.

Sliding mechanisms Entry door openings are rarely used due to the complexity of design and installation.

Entrance doors can open inside the room or outside to the street. Depending on your preferences and needs, you can choose any of these door opening options. However, it should be borne in mind that when the front door is opened to the outside, much less heat leaks out. The degree of reliability and security against burglary is also lower when the door is opened from the outside.

Another sign by which the type of entrance door is determined is the direction in which it opens. There are doors that open from left to right, and there are also products that open the other way around. The opening side indicator has a very important in case of insufficient quantity usable space (landings apartment buildings, narrow corridors, entrances to underground premises).

Metal door classes− this is one of those concepts that companies that are engaged exclusively in sales and have nothing to do with the production of doors really like to “play on.” Currently on Russian market iron doors are presented in large assortment, and their price range is very wide. At the same time, it is not always clear to the buyer why this or that door costs exactly that much and why they need to overpay if they all look the same in appearance or differ only in finishing. This is where some sellers try to create confusion in the terminology, separating “iron”, “steel” and even “armored” doors into different price categories.

The price of an iron door, depending on many factors (design, finishing, etc.), will, of course, be different. However, you need to know the basics: the frame of any metal door is sheathed with steel sheet. And steel is an alloy of iron and carbon with other elements. Therefore, you should not trust sellers who use synonymous words to divide essentially the same products into different categories.

It would be more correct to pay attention to what classes of metal doors are distinguished GOST 31173-2003, since it is there that the technical description of steel door blocks is given. So, according to state standard, the classification of these products includes six characteristics.

Signs of classification of metal doors

1. Purpose

Firstly, appointment: doors can be external (entrance to a building) and internal (entrance to an apartment or room inside a building).

2. Design

Secondly, design. They may differ according to the following criteria:

• frame type: closed box, U-shaped box, U-shaped box with the possibility of adding a threshold;
• number of canvases: single-field, double-field, with horizontal or vertical inserts;
• direction and opening: inward or outward, left or right.

3. Finish

The third sign of door classification is finishing. This is what, perhaps, first of all a potential buyer pays attention to. Manufacturers offer opportunities wide choose finishing options. In accordance with GOST, they can be divided into painting with paint and varnish or powder compositions and lining with leather, film, wood, metal, glass or a combination of materials.

4. Operation

The next important component is performance. They combine such indicators as heat transfer, sound insulation, water and air tightness. Each of them has three subclasses that can be combined with each other in different combinations, depending on the design.

5. Durability

The fifth characteristic is also worth paying attention to, because it is this that determines the ability of the entire structure to resist burglary - this is strength. Strength classes M1, M2 or M3 are assigned to the product after passing tests for static, dynamic and impact loads. The class is given based on the worst result of any test.

6. Protection

The last and perhaps most important characteristic in the official standard classification is protective properties. Despite the appearance and performance characteristics, the main thing that is required from a steel entrance door is to be a reliable barrier against intruders. According to certain characteristics, the product is classified into one of three versions:

• Normal: when the structure has simple locks and a locking anti-removal device;
• Reinforced: in addition to the “regular” one, there is a multi-point lock with perimeter locking. Strength not lower than M2;
• Protective: Same as "reinforced", but the product's strength corresponds to M1 and meets additional requirements standard

Classification by price category

However, it is worth noting that from the consumer’s point of view, the classes of metal doors defined by the state standard are very complex system. Therefore, the gradation by cost (“economy”, “business”, “elite”) used by manufacturers is quite reasonable. In a certain price category, they combine doors that can combine different characteristics. For example, a door with multi-bolt locks sheathed in thick sheet steel will not necessarily be expensive if you choose simple powder enamel as the finishing material. Conversely, a thin steel sheet lined with hardwood panels in combination with increased sound and thermal insulation will cost more. Although such a product will not have high protective properties.

When choosing a metal door, you should look for a responsible manufacturer who carefully fulfills the requirements of GOST not only in terms of finishing, but also in terms of security and strength. door block.
