What are the types of profiles for drywall and how they are used. Types of profiles for drywall: dimensions and purpose Mounting profile for drywall

With it, you can bring to life various design ideas from arches to multi-level ceilings. All of these designs are mounted on a lightweight durable . For those who are faced with this task for the first time, it is difficult to immediately understand the variety of their types. We will tell you what sizes and types of drywall profile are, for what purposes you can use it.

What is a metal profile

It is a channel, the walls of which are responsible for the rigidity and reliability of the base, and the back serves to attach to a vertical or horizontal surface. For its production, cold-rolled billets of aluminum or steel are used. The first have excellent characteristics, but their price is higher. Therefore, steel is more popular.

Conventional black metal profiles are suitable for living rooms and, i.e. those rooms where normal operating conditions. Galvanized have anti-corrosion properties, so they are used in rooms with high humidity - kitchens, bathrooms.

Profile types

Products differ in appearance, purpose and parameters. Dimensions are considered in millimeters.

There are the following types of drywall profiles and their purpose.

guide

It is designated by the PN or international UD marking and is a base that is mounted along the edge of the future structure and where the rack channels are then attached. Used for walls and partitions. It has a U-shaped section and smooth side walls. Dimensions of the drywall guide profile: depth 40, width 50, 75, 100 (depending on wall thickness), length 3000.

Ceiling guide (PPN)

Needed for mounting suspended frames: it is screwed along the edge of the structure, and then ceiling models are inserted into it. In addition, it can be used as a rack-mounted frame for mounting when finishing the surface with drywall,. Dimensions: depth 27, width 28, length 3000.

Ceiling (PP)

Suitable for single and multi-level device. It differs from PPN in that it is mounted to the ceiling with special parts. It can also be taken for wall cladding using GKL. In order to save as much as possible the height of the room eaten by the ceiling, it is customary to make its depth small - 27. The remaining parameters are width 60, length 3000.

Rack (PS or CD)

It is the main detail in the construction of interior walls and partitions. It has a C-shaped section. It is inserted into a frame created from guide models, so its side walls (shelves) are slightly bent inward. In the backs of this type there are holes for technical communications. Parameters: depth 50, width varies - 50, 75, 100, length 3000.

An example of mounting a rack model. The dimensions and types of the partition profile for drywall depend on the configuration of the structure: walls, niches and shelves.

Auxiliary

• Beacon (PM) - with its help you can direct the rule during plastering.
• Corner (PU) is used to strengthen the end faces of the GKL at the corners. There are holes on its surface for free penetration of the finishing solution into the base.

Other types

Other varieties used in individual cases: arched and reinforced. Arched or flexible is needed for and rounded ceiling structures. Dimensions: width 60, length 3000. However, its price is quite high. Therefore, in order to save money, experienced craftsmen use ceiling models (PP). With scissors for metal, cut the sides and bend them to the desired contour.

Reinforced (UA) is used as a rack when in partitions. Since this section takes on the weight of the door leaf, it is reinforced to 2 mm (for Knauf) and 1.5 mm for other companies. Other dimensions: depth 40, width 50, 75, 100, length 3000, 4000, 6000.

Choice of thickness

This is the main indicator of the reliability of the future structure. The thicker the product, the more possibilities of its application. This indicator differs for different manufacturers - from 0.35 to 0.6 mm. Interior walls, partitions are advised to be erected using channels 0.6 mm thick. If you choose thinner types, then when installing GKL sheets, the screws can scroll, and the structure itself can bend, which will reduce its strength. In addition, cabinets will probably be hung on the future wall. The reliability of their fastening on a wall with a thin profile will be a big question.

Manufacturing companies

The most famous profile company is the KNAUF plant. All manufactured products are of the same thickness - 0.6 mm. In addition, it is distinguished by precise dimensions, high-quality raw materials. Each product has a name and technical parameters. However, their cost is quite high. Gyproc is a worthy competitor. All channels produced by them are perforated, so even with a thickness of 0.5 mm they are stronger than smooth-rolled with their 0.6 mm. However, according to the reviews of the masters, it is not convenient for everyone to work with corrugated ones due to the difficulties of inserting rack-mounted rails into guides. The Russian company Metalist, which produces galvanized models, operates in the middle price segment. There are other manufacturers as well. The quality of their products may differ in the composition of raw materials, product configuration. In some, additional grooves have been added to increase rigidity, holes for fastening.

What profile is needed for plasterboard walls

In order to correctly calculate the number of profiles, you can draw a design plan, indicate the types and dimensions of the models. Painted products can be found in some hardware stores. Consultants say that it serves as additional protection for the material. But it's not. Most often, a factory defect is hidden under the paint. Therefore, buying such a product is extremely risky.

What profile is needed for a plasterboard partition? When choosing between smooth and corrugated varieties, you need to keep in mind that corrugated types are not suitable for installation. Any building can shrink. And channels with an uneven surface are fixed rigidly. As a result, cracks may appear on drywall sheets.

In building stores, the standard length of these products is 3000 mm. However, manufacturers produce models of different lengths - from 2500 to 6000 mm. Therefore, if necessary, you can order a non-standard size from the seller. Pay attention to the economy profile. It differs from standard products in reduced dimensions, thickness, lower price. The scope of its application - and ledges. Experienced craftsmen do not recommend mounting partitions or ceilings with it.

Greetings, comrades! Today we have to find out what drywall profiles are, for what purposes they can be used and how they are mounted. In addition, we will analyze a couple of basic structures that are the basis of almost all types of interior decoration using gypsum boards.

This is how a profile for mounting GKL is made. We have to study its varieties.

Why profile

As you know, not only galvanized profiles, but also a bar are used for the installation of frames and battens under the gypsum board. Which material is better?

The answer is quite unambiguous: profile. Arguments at your service:

• Galvanized steel lasts indefinitely regardless of atmospheric humidity. Of all the negative impacts, the steel profile is only afraid of corrosion, from which it is reliably protected by a zinc coating layer;

The anti-corrosion properties of the zinc coating make it possible to use galvanizing as a roofing material.

• Galvanization is not afraid of insect attacks, which in some 10-15 years are quite capable of destroying or rendering the wooden frame unusable;
• The geometry and dimensions of the steel frame elements are unchanged, while the bar will lengthen and warp with each seasonal increase in humidity. Changing the shape of the frame will predictably cause cracks between the skins or even right along them.

The warping of the frame bar led to a logical result.

GKL, however, can be mounted on even wooden walls without crates, thereby reducing the misuse of the usable area of ​​the room. It is also used for leveling walls made of mineral materials on adhesive beacons. In this case, the sheet is glued onto a spot-applied gypsum adhesive or any leveling gypsum mixture.

Titles

What types of profiles can be found on sale?

For the assembly of frames and crates, only 4 of their types are used:

Ceiling CD and ceiling track UD.

However, if desired, two more varieties can be found in hardware stores:

1. Arched (flexible). It is able to bend in an arc with a small radius, forming vaults of arches or bends in the edges of multi-level ceilings;

Thanks to the perforation, the U-shaped profile is able to bend with a small radius.

1. Angular. A perforated galvanized corner is laid under the putty to reinforce the outer corners of walls, door and window openings.

Galvanized corner profile to reinforce external corners.

The corner profile is made not only from galvanization, but also from PVC. Plastic reinforcing corners are often supplied with a reinforcing mesh.

In the future, we will turn our attention, first of all, to those types of drywall profiles that are used to assemble rigid frames and battens - CW, UW, CD and UD.

Functionality

How do the types of drywall profile and their application compare? To answer this question, it is enough to reread the titles.

• Rack-mounted is used for mounting vertical racks when assembling wall frames and partitions. It can also be used as jumpers between racks, reinforcing the rigidity of the frame;

The main element of the wall frame with niches is the UD rack.

• The guide is mounted on permanent structures (floor, adjacent walls and ceiling). The edges of the racks are inserted into it;

The UW rail is used to fasten the partition frame to the walls and ceiling.

• The ceiling and ceiling guide are used in the same way when installing the false ceiling battens. With the same success, they can be used to level walls with large (over 50 mm) blockages, bends and drops.

Racks have sufficient rigidity to withstand bending loads, but the ceiling profile, due to the low height of the side walls, needs additional fixation. For this purpose, suspensions are used - straight and adjustable.

Direct suspension for mounting GKL.

With insufficient length of the ears, two straight hangers can be connected in series, thereby increasing the maximum distance from the main structure to the cladding.

Dimensions

What are profile sizes?

First, let's get acquainted with the standard sections of the main varieties:

• All ceiling profiles for drywall have the same wall size - 60 and 27 millimeters;

Ceiling CD dimensions.

• Ceiling guides are compatible with them - 27 and 28 mm, respectively;

Section of the UD profile.

• Rack-mounted have side walls 50 mm high, but the width (bottom wall) can be 50, 75 or 100 mm;

The wider the post, the greater its rigidity in relation to the bending load.

• The height of the side walls of the UW guides is 40 mm, the width of the guide corresponds to the width of the uprights - 50, 75 or 100 mm.

With length, everything is somewhat more complicated. Theoretically, according to the assurances of the manufacturers, all varieties are produced with a length of 2.5 to 6 meters inclusive.

The assortment declared by the manufacturer is not always consistent with what we see on the windows of building stores.

In practice, the range of products in stores is much smaller:

• For guides and ceiling guide profiles, the standard length is 3 meters;
• For rack and ceiling - 3 and 4 meters.

If the maximum length of the ceiling profile is insufficient for your purposes (that is, less than the length of the room or the height of the wall to be leveled), so-called straight connectors are used to splice products of shorter length. In addition to them, on sale you can find cross connectors - "crabs".

Direct connector for ceiling CD.

Price

How much do galvanized elements of crates and frames cost? I will give the current prices (November 2016) for the Leroy Merlin chain of stores.

The actual cost depends not only on the section and length of the profile, but also on the thickness of the metal from which it is made. Galvanized products with a thickness of 0.55 - 0.6 mm are indicated in the company's price list with the words "premium" or "strong" and cost the buyer about one and a half times more than "economy" class profiles (0.4 mm).

The last number in the marking indicates the wall thickness in millimeters.

Mounting

So, we have studied the classification of profiles and their purpose. It's time to move from theory to practice.

General rules

Here are a number of installation rules common to all types of frames and crates:

• For cutting galvanized metal, only scissors for metal can be used. Abrasive cutting with a grinder with a circle for metal is highly undesirable. The fact is that heating the cut area leads to the burnout of the anti-corrosion zinc coating, and the edge of the frame element remains defenseless against rust;

Use only metal shears to cut the profile.

• Guides, guide ceiling profiles and suspensions are attached to brick, stone and concrete surfaces with dowel screws. The size of the fastener depends on the strength of the surface: for heavy concrete, a size of 40x4 mm is sufficient, and for loose aerated concrete or shell rock, it is better to increase it to 80x8;
• When fastening the guides, the wall, ceiling or floor is drilled with a puncher directly through the profile pressed against them. Then a dowel-screw is inserted into the drilled hole and twisted with a screwdriver. Such a mounting scheme will save you from the problem of matching the holes in the profile and the capital structure;

The hole in the ceiling is drilled straight through the profile.

• The step between the attachment points of the guides should be about half a meter;
• Suspensions along the profile on the ceiling are mounted in increments of 60 cm, and on the wall, where the suspension experiences a minimum load - 80;
• It is strictly forbidden to use wooden chopsticks to fasten guides in wet rooms. In an atmosphere with periodic fluctuations in humidity, they quickly dry out and fall out of the holes;
• To connect the profiles to each other or with suspensions, self-tapping screws for metal 9 mm long are used. Self-tapping screws are screwed in only with a screwdriver: it is almost impossible to connect two profiles with your own hands, using a screwdriver;

In the photo - a corded screwdriver, which I use to assemble drywall structures.

• The standard step between racks or crate elements is 60 centimeters: this is exactly half the width of the drywall sheet. The step is measured not between the edges, but between the axes of the frame elements. In this case, the seam between adjacent sheets will fall exactly in the middle of the profile;

The standard step between the frame elements is equal to half the width of the drywall sheet.

• If the structure during operation will experience significant loads (for example, when it comes to a wall in a narrow hallway), the step between the profiles can be reduced to 40 or even 30 cm. The main thing is that the width of the plasterboard remains a multiple of this step;

Reinforcement of the partition frame can be achieved without increasing the thickness or reducing the pitch of the posts - by inserting a bar with a section of 50x50 into each of them or by connecting the posts in pairs (by inserting one CW into another or simply fixing them next to each other).

The rigidity of the frame can be increased by nesting the racks into each other.

Paired racks made it possible to assemble a partition of minimum thickness with acceptable rigidity.

• For sound insulation, a damper tape is placed under the guides. It dampens acoustic vibrations, preventing their transmission from the plasterboard to the capital structures of the building;
• Door and window blocks (including metal-plastic) are attached to the side profiles and horizontal lintels with self-tapping screws 16 - 32 mm long (depending on the thickness of the frame), screwed through the profile. As a seal and to strengthen the connection, it is worthwhile to first apply a strip of mounting foam to the outer surface of the block.

The door block is placed at the frame assembly stage.

Suspended ceiling, wall alignment

How to mount profiles under drywall when assembling a single-level false ceiling?

Step by step instructions - at your service:

1. After marking the horizontal line of the ceiling, fix the UD guide along it. You can safely use additional segments of any length, the main thing is that at the junctions with the ceiling CD, the guide is securely fixed;
2. Mark the lines along which the ceiling profiles will be mounted, and fix the hangers along these lines;
3. Cut (or connect) the ceiling CDs to length and insert them into the guides;
4. After aligning each CD according to the long rule, pull the hangers to its side walls;
5. Bend the ears of the hangers towards the ceiling.

Ready-made ceiling crate.

If you are assembling a crate to level the wall, all the steps are completely identical to those described above, adjusted for the vertical orientation of the frame.

Partition

How to assemble a partition frame?

In general, this is done like this:

1. Using a plumb line, mark the axis of the partition on the ceiling, floor and adjacent walls;
2. Fasten guides along this line;
3. Mark the position of the racks on the ceiling and on the floor, using the same plumb line;

The markings should remain visible even after the frame is sheathed with drywall. It will help you secure the sheets to the uprights hidden by the sheathing.

1. Cut the racks to length and line them up with marks;
2. Fasten each upright to the rails on both sides.

The frame of the interior partition is ready for plasterboard sheathing.

A special case is the assembly of a soundproof partition. In this case, we need to decouple the wall cladding on both sides acoustically. The goal is achieved by assembling two independent frames at a small (within a centimeter) distance from each other.

Conclusion

So, we got acquainted with the varieties of galvanized profile under the GKL and with the technique of their installation. As always, the reader can find additional material in the video in this article. I look forward to your comments. Good luck, comrades!

Types of drywall profiles: dimensions and purpose

Plasterboard sheets are effectively used in the process of finishing work, but their fastening is impossible without a special frame made of metal profiles. As an alternative, fastening with special glue can be used, but it is the profiles that ensure the reliability of the structure. Moreover, when creating different frame designs, different categories of these fasteners are used.

Drywall Profile Types

The classification of metal profiles for drywall installation can be based on their functionality, design features and scope.

Depending on the place of application, profiles differ:

In addition, in the classification of profiles for GKL, there are varieties:

• Plane sheathing profile
• Profile for the device of partition structures

Varieties of profiles for drywall, depending on the shape, are:

• flat
• corner
• In the form of a channel

Steel is used as a material in the production of metal profiles for drywall, and usually galvanized. For different functional purposes of the profile, thin-sheet or thick-sheet galvanizing can be used.

A more detailed description of the profiles gives an idea of ​​the purpose of these structural elements of drywall systems.

Profiles for creating the main frame

This role applies to:

• Guide profiles with UD marking. Such profiles are used in the formation of the frame of the future drywall construction. Since the entire system, including partitions and the drywall itself, is attached to this profile, it is made from a thick steel grade. This type of profile sets the parameters for the future perimeter of the entire structure.
• Carrier profiles with CD marking. This type of profile is attached directly to the UD frame profiles, and performs a load-bearing function in accordance with its name. Since drywall sheets are also attached to them, they must be made of thick galvanized steel.
• arched profiles. In terms of technological features, this type of profile is identical to the two previous types, however, it has reinforced perforation with many holes and cuts. This makes it possible to bend it in the right direction, forming a frame of complex configurations.

Partition profiles

Here, too, an identical classification has been developed, including

• Guide profiles with the UW marking, designed to create a structure cladding. With their use, the configuration and perimeter of the wall are established
• Rack profile marked CW - an element to stiffen the entire structure. Drywall sheets can be mounted on it on both sides

Dimensions of profiles of different categories

Since each type of profile has its own functional purpose, the dimensions and shape of the profiles are also different.

• So, for example, UD marking guide profiles have dimensions of 0.25-0.28x300 - 400 cm. The wall thickness of the profile is 0.5-0.7 mm
• Carrier profiles CD have dimensions of 0.25-0.28x300 cm, as well as 0.28x400 cm. In both cases, the height of the shelf is 0.5-0.6 mm

The weight of the supporting and guiding profiles for the frame is 1.2-1.8 kg with a length of 3 m, and 1.6-2.4 kg with a length of 4 m, which depends on the thickness of the steel.

Profiles for partition walls are usually wider. Their sizes are as follows:

• UW brand profiles can have a width of 50,75,100 mm. The length of such profiles is 3000 mm or 4000 mm. The mass of each profile reaches 2.19-3.88 kg, depending on the other dimensions
• Rack profiles CW, depending on the purpose, have the following dimensions:
  • 48.8x3000x50
  • 73.8x3000x50
  • 98.8x3000x50

Profiles of this type can also be produced with a length of 4000 mm and the same parameters for the width and height of the shelf. In all cases, the thickness of the metal is not less than 0.5-.6 mm.

Dimensions of different types of drywall profiles

Fasteners for drywall profile

For complete fastening of profiles, it is also required to use fastening fittings. It is used to connect individual structural elements of the frame, as well as to fasten drywall sheets. The types of fasteners for gypsum boards are classified into the following categories:

To connect the surface of a wall or ceiling with a metal frame made of a metal profile, a bracket in the form of the letter "P" is used. It is easily bent at the fold and contains perforations throughout its area.

• Suspension for quick attachment - quick suspension. It has a special spoke with a hole, which helps to connect those parts that cannot be fastened with a U-shaped bracket.
• The cruciform bracket is used as a jumper on the supporting profiles and makes it possible to connect them at a right angle
• To increase the length of the carrier profile, a connector is used into which the ends of the profiles are inserted.

And in order for the fasteners to be held in the structure of the drywall system more reliably, screws, self-tapping screws and dowels are used for their fastening. Their dimensions are selected based on which element or surface will be fastened to.

Materials for fastening profiles

Conclusion

For a professional master, a brief description of the parameters of all the structural elements of a drywall construction is usually sufficient. However, if you have to face this device for the first time, it is better to get visual information. To this end, it is recommended that you familiarize yourself with the video, which allows you to delve deeper into the process of choosing drywall fasteners and clearly demonstrates the characteristics of each of them.

In conclusion, it should be noted that one should not neglect individual varieties of drywall profiles or fasteners, replacing them with those that are available. Sometimes this practice leads to the fact that the drywall system is unreliable.

What are drywall profiles and how to choose them?

Mounting light and versatile drywall constructions is very simple even for a beginner in this business. It is enough to study the sequence and technology of installing the frame, make accurate measurements, a drawing, buy the necessary materials and arm yourself with the necessary tools.

It doesn't matter if you are going to make a false ceiling, a wall, a prefabricated partition, a door arch or plasterboard wall cladding, metal profiles will be the basis of any design. It is from them that they form the frame on which the drywall sheets will be located. Modern products are made of thin, but durable metal plates. They have a wide range of applications, give rigidity to plasterboard structures without weighing them down, and are also very convenient to use. Bent metal slats are indispensable in creating intricate decorative elements for your home.

What are the types of profiles

If this is your first time working with drywall, check out what are the main types of profiles for creating a rigid frame. A huge number of their types and fastening elements can confuse a novice master.

Six main types (markings) of metal profiles:

• Guides for assembling the frame (PN) or (UW). Their standard depth is 40mm, width - 50mm, 75mm or 100mm, depending on the thickness of the wall. Judging by the name, this guide product is a kind of rail, the basis for the subsequent fastening of rack and ceiling guide profiles.
• Ceiling guides (PNP) or (UD) have the same functions and are designed for mounting the ceiling base under plasterboard sheathing. This type is indispensable for the installation of multi-level suspended ceilings.
• Ceiling (PP) or (CD) is attached to the ceiling with direct hangers or anchor clamps. From this type of rails, the ceiling frame itself is formed.
• Rack (PS) or (CW) is used for mounting the foundation of future plasterboard partitions and walls, it is fixed directly to the guide profile.
• Beacon profile for leveling the wall (PM), it can be called a rail along which the rule goes. It is very convenient to use when plastering walls.
• The corner profile is intended for alignment and strengthening of corners (UE).

Devices for fixing different types of profiles are: crab connectors that create their cross-perpendicular fastenings in the frame, extensions for various combinations of metal segments, anchor clamps, straight hangers, two-level CD connectors and others.

To create structures from profiles, you will need pliers for fastening them without screws (clip profile), a cutter, a peeling planer (rasp), a bending tool, wire cutters. When calculating the required number of products of each type, do not forget that their standard length is 3 or 4 meters.

Any specialist, having familiarized himself with the design of a drywall construction, asks the question - what materials will be required in the manufacture of its frame. Naturally, for a “knowledgeable” person, the solution to this problem will be absolutely no difficulty, but what about a novice home master? We decided to help the craftsmen who will assemble the frame for the first time, having examined in our article the types of drywall profile and its dimensions.

1 - UD; 2 - CD; 3 - CW; 4-UW

Note that the story only about the types of metal profiles for drywall, as about one structural element, in our opinion, will not bring much practical benefit. Therefore, we decided to add here a description of fasteners and related materials used in various ways of mounting the frame.

The main types of drywall profiles

This, without a doubt, the main structural element, has several varieties, four of which are designed to assemble the frame and are made of thin steel by cold rolling.

Guide - PN (English UW)

It is used in the creation of partitions and wall decoration, being a guide to which racks are attached. This drywall wall profile has the following dimensions (mm).

Drywall has long taken a strong place in the building materials market. Usually such material is attached to the crate.

The main structure is a frame of vertical and horizontal profiles. Their range is classified by type, size, purpose and other characteristics.

Peculiarities

The modern profile for gypsum plasterboard provides great opportunities in creating a variety of geometric shapes and forms. It helps to avoid monotony in the interior. With it, you can make an original false ceiling and any module, sheathe walls, assemble an internal wall, partition and many other structures.

The unification of profile structures facilitates the work of professional craftsmen and home craftsmen.

The metal frame for plasterboard sheathing is much stronger than a similar construction of wooden beams.

The profile is made on special machines, which allows to achieve accuracy in size and ideal lines. In addition, metal is more durable than wood.

The peculiarity of the calculation and selection of profile sizes is that they must be produced based on several factors.

One of them is the thickness of the drywall sheet, which affects the overall load of the structure. This is especially important when choosing rack profiles.

If a single-layer lining of the profile with drywall is assumed (load up to 8.5 kg per m²), it will be sufficient to use products with a size of 50x50 or 50x40 mm. If the expected load is higher, a 65x50 or 75x50 mm profile should be used.

Kinds

In order to avoid mistakes with the choice and confusion in a diverse range of drywall profiles, certain knowledge of their types may be required. Among themselves, they differ in dimensional characteristics, metal thickness, cross-sectional shape and raw materials from which they are made.

The main profiles for creating frame bases for ceilings and walls are of several types.

guide

Such a profile is marked PN (UD), which means "guide profile". Its cross section has a U-shape, the side walls are smooth, holes for fastening are made in the back.

The guide or starting profile is used to create the main support (for racks and lintels).

It is attached around the perimeter of the structure, subsequently the remaining components are installed in it.

rack

This option is marked PS (CD), which means "rack-mount profile". It is inserted into the guides, drywall sheets are attached to it. In this regard, it bears the main burden. That's why the rigidity of the rack profile should be maximum.

Its cross section has the shape of the letter P, but the design of the PS is equipped with additional shelves and stiffeners.

Ceiling

It is marked PP and PPN, which means "ceiling guide profile" and "bearing ceiling profile". The sections of PP and PPN are shaped like the letter P, but are smaller than those of the wall profile. The ceiling profile has shelves of lesser height and stiffeners. The small height of the shelves is due to the need to reduce the "selection" of height from the room with a plasterboard ceiling.

Reinforced for ceiling

Has UA marking, metal thickness is 2 mm. It is used to create reinforced frame bases for suspended ceilings.

In addition, it is used as part of the structure for fastening window and door frames.

Arched

It is a kind of rack and guide profiles. It is abbreviated as PA (CD). Used to assemble structures with radial bends.

The main distinguishing features for this type are pronounced perforation and the presence of side cuts, which provide an opportunity for bending the profile. In some cases, the arched profile can be made independently by cutting the shelves of the ceiling plinth into sectors, and then bending in a given radius and direction.

Partition

• guide. It is marked UW. It is similar in principle to the UD profile, but has slightly different characteristics: greater height (40mm) and width (usually 50, 65, 75 and 100 mm).
• Carrier or rack. It has a CW marking and a shelf height of 50mm.

Additional profiles and accessories

When creating structures that use drywall and metal profiles, additional elements cannot be dispensed with. Their range is varied and includes several varieties.

Angular

It has a rectangular section with a slightly protruding center part.

It is used to form the corners of plasterboard structures.

Corner profiles also have several subspecies:

• Both shelves are perforated with large holes, which allow the corner to become part of the plaster layer and thus be securely held.
• with mesh, which is glued along the edges of the profile in the form of strips. As a result, enhanced adhesion is achieved with subsequent finishing measures.
• On a paper basis. In this case, 2 metallized strips are glued onto high-density paper. Such elements are used where a small load is expected (in window openings, edges of shelves and niches).

Beacon (PM)

It is used as a beacon or a supporting guide in order to acquire a more even surface when plastering. The most widely used beacon profiles are 3 m long and have sections: 22x6, 23x10, 62x6.6 mm.

Perforated hangers

metal

Metal anchor hangers for ceiling profiles are used for the design and installation of suspended ceilings.

With the help of anchor hangers, it is easy to adjust the height, as well as to set the ceiling plane.

Connectors

A single-level and two-level connector for a ceiling profile is called a "crab". It is a plate with clamps for fastening cross profiles.

Used for suspended ceilings.

Extension

The profile extension is a small bracket measuring 110x58 mm for splicing two pieces of the same size.

materials

Profiles for drywall are made of steel and aluminum. Steel profiles (plain or galvanized) are more common in finishing work.

Aluminum, despite the excellent properties of the characteristics, are much more expensive.

Dimensions

For the convenience of installation work and to make it easier to choose the material for work, the standard sizing system for drywall profiles provides several options for the main parameters. Guide profiles come in various lengths and widths, but the main dimensions of the PN profile are as follows (the first parameter is the width, and the second is the height):

• 28 x 27(for wall and ceiling structures);
• 50x40mm, 65x40mm(some manufacturers have a CD profile width of 60 mm);
• 75x40mm, 100x40mm(for partitions).

As for the length, it is usually presented in four versions: 2.5 (2.6), 3, 3.5 and 4 meters. If a longer profile is required, for example, 5 m, it is made to order or connected from separate segments. The wall thickness depends on the manufacturer, it can be from 0.4 to 0.6 mm.

Rack profiles, as a rule, are produced in the main four sizes:

• 50x50mm;
• 65x50mm;
• 75x50 mm;
• 100x50mm.

Their standard length assumes sizes of 2.5 (2.6), 3, 3.5 and 4 m. Many metal-roll manufacturers accept orders for products of greater length.

Ceiling profiles have a size of 60x27 mm (ceiling guide) and 27x28 mm (ceiling carrier).

What to cut?

Before you start working with a metal profile, you need to find out how it can be cut. It is necessary to prepare the appropriate tools. Usually, a jigsaw, a grinder, a hacksaw or metal shears are used for this.

Electric jigsaw

A metal file is installed in the tool. Cutting starts from one of the edges of the profile. First, the back part is sawn, and then the side faces. When using this method, a high quality cut and the absence of burrs are noted.

Bulgarian

Angle grinder (angle grinder) will be an excellent assistant in profile cutting. With this tool, the cut will turn out faster than using a jigsaw.

However, working with an angle grinder requires certain skills. With a lack of experience, there is a high probability of leaving the marking line and getting an oblique cut.

hacksaw

When work with power tools is not available, an ordinary hand saw for metal comes to the rescue. In this case, the cut must be started from the edge, then it is necessary to go to the back and side parts of the profile.

The inconvenience of this method lies in the fact that in the process of cutting under mechanical action, the profile can be deformed. In addition, the time and power costs are much higher than when working with an electric jigsaw or grinder.

Scissors for metal

This is a fairly simple and most common way to cut a metal profile. The cut with scissors is made strictly along the marking line. Using a quality tool is one of the guarantees of getting a beautiful cut.

The most difficult thing in this method is the probability of leaving the marking line when passing the edge.

A flawless result may require a little practice or a combination of sawing the ribs with a hacksaw followed by cutting with scissors.

Despite the fact that the dimensions of the profile elements are sufficiently standardized, it is desirable to form a set of profiles for creating a metal frame from the assortment of one manufacturer. Otherwise, you run the risk of encountering some inconsistencies, such as: various parameters for the length, width and depth of the profile, metal thickness, and also its quality. This significantly increases the risk of mounting a metal structure with reduced strength. This may affect the final result of the work.

When choosing the thickness of the sheet, you need to think about what the thicker the metal, the stronger the structure, but its cost also increases. Therefore, experts recommend optimizing all parameters and stop at the choice of metal 0.5 mm for ceilings and 0.6 mm for walls. The thicker the metal, the more reliable the design will be. The economy option using thin steel may not withstand significant loads.

In 1980, a paper mill owner named Ostyug Sackett came up with the idea of ​​creating a new building material from gypsum. At first, drywall sheets replaced plywood and chipboard in small houses. It was then that the interesting properties of this material were discovered. The joints of smooth and even cardboard are very easy to repair so that when painting or other types of finishing, they will be completely invisible. Breaking a marked sheet, instead of sawing, is much easier. Dimensional stability eliminates cracks in the joints ... Drywall has established itself in the construction market for a long time and has remained an integral part of the repair to this day.

This or that drywall construction is necessarily supported by a frame made of strong and stable parts. These are guides and profiles of various shapes, which are interconnected using special fasteners. They differ in purpose and application, as well as in size and quality. It is very important to make the right choice when buying, the result of the work will depend on this. Indeed, if you take a bad profile or simply not suitable for a certain type of work, the design will eventually have to be redone. For example, the sheet on the partition will bend or “go” to the side, gaps at the joints will become visible, or a noticeable “wave” will appear on the wall itself. In order to avoid mistakes during repair and construction, you need to study the types and sizes of drywall profiles well. Find out what kind of material is needed for the construction of a particular structure.

Rack profile (referred to as: CD or PP).

Perhaps one of the most popular profiles for installing drywall on the ceiling. This type provides reliable fastening of sheets. And if you choose the right dimensions, then the work space will be used as economically as possible, leaving almost no waste.

CD or PP dimensions:

• Profile length - from 2.5 to 4 meters
• Width - 60 millimeters
• Shelf height - 27-28 millimeters

Guide (UD or PPN).

Profiles are used for the construction of a false ceiling. These elements are mounted over the entire area of ​​​​work, because by fixing sheets of cardboard, the drill passes directly through them. It is advisable to purchase guides that already have cut holes (perforated profiles). Then it will be much easier to carry out installation.

• Thickness - 0.55 millimeters
• Length - 3 meters
• Width - 27 millimeters
• Height - 28 millimeters

Profile (UW).

This view is very similar to the above UD. It is applied similarly, but has different sizes:

• Length - from 3 to 4 meters
• Width from 5 to 10 centimeters
• Shelf height - 40 millimeters
• Metal thickness - from 0.4 to 0.6 millimeters

Partition profile for drywall. Sizes and types.

Guide profiles (UD).

This type is suitable not only for ceilings, but also for plasterboard partitions and wall cladding. Let's take a closer look: in the back of these products there are holes for dowels (8 millimeters). The profiles are shaped like the Russian letter "P", and also differ in size.

Dimensions: (the first number is the width of the back, the second is the width of the shelf)

• 50 x 40 millimeters
• 65 x 40 millimeters
• 75 x 45 millimeters
• 100 x 40 millimeters

Rack profile (CD).

For partitions, this species has special grooves along the shelf. The two extreme ones are intended for screwing in self-tapping screws, and the one in the middle indicates the place of joints of drywall sheets. The width of the back of the rack is identical to the guides. Because the PS is inserted into the PN.

Available sizes:

• 50 x 50 millimeters
• 65 x 50 millimeters
• 75 x 50 millimeters
• 100 x 50 millimeters

Reinforced (UA).

The profile is used for doorways in partitions. The main quality is strength and resistance to corrosion.

Profile dimensions:

• length - from 3 to 6 meters
• the height of the side parts - 40 millimeters
• base width - 50 - 100 millimeters
• workpiece thickness - 2 mm

Corner - (PU protective).

Designed to protect the corners and ends of plasterboard partitions from mechanical damage. There are holes on the surface of the profile for the finishing solution to penetrate into them.

• Length - 3 meters
• Section - 25x25x0.4 mm, 31x31x0.4 mm, 31x31x0.5 mm

Beacon profile (PM).

Used for finishing work. Fastened with mortar to the required level. Helps to putty (or plaster) the wall evenly.

• Length - from 2.5 to 3 meters
• Width - from 22 to 60 millimeters
• Metal thickness - from 0.33 to 55 millimeters
• Beacon protrusion - from 6 to 10 millimeters

Arched profile (PA) for drywall. Sizes and types.

This profile has cuts along the edges, thanks to which the metal product can be evenly bent and adapted to the construction of almost any complex structure. For example, make an arch or a shelf in the wall, of an unusual shape. There are both concave and curved types of arched profile.

Dimensions of concave arched profiles:

• Radius from 500 to 5000 millimeters
• Length from 2600 to 4000 millimeters

Convex profiles can be:

• Radius from 1000 to 5000 millimeters
• Length from 400 to 2600 millimeters

Aluminum and galvanized drywall profile. Sizes and types.

Profile for drywall, made of different metals, consider the most common types: aluminum and galvanized, as well as their characteristics.

Aluminum profile and its features.

Such a profile is not cheap, but it has an excellent characteristic, so the high price is justified. Such profiles are good for building window frames or finishing household appliances. For example, if you need to make a niche for a washing machine in the bathroom. This product is distinguished by its long service life, strength and lightness. Does not weigh down the entire structure and is very easy to install. Plastic and resistant even to low temperatures. Builders recommend buying aluminum profiles for wall and ceiling cladding.

Profiles of this type are made of both cold aluminum and warm aluminum. Cold-formed is made of metal 4 mm thick, while bending without heating. It differs in shape (P, W, T, H - figurative). Withstands loads up to 1.5 kN per 1 meter of wall.

Galvanized profile.

The galvanized profile is not inferior in price to aluminum. It is used for the construction of the base of the frame, in rooms with high humidity - in the kitchen or in the bathroom. This is because it is resistant to rust and does not require additional treatment with anti-corrosion agents. Like aluminum, the profile is light and soft, it will not be difficult to screw screws into it. Galvanization is also used to create additional stiffeners if drywall sheets are thicker than 12.5 millimeters.

There is also a plastic profile. Its purpose is to close the joints of drywall sheets at the outer corners, giving a beautiful look to the finish. And also, they cover the transition of drywall and other material, such as wood.

Additional accessories for fixing drywall.

In order to assemble the crate, you will need auxiliary parts:

• Two-level connector for CD-profile. Such a part is sold in an expanded, flat form and before starting work it must be bent in the shape of the letter P. It is used to connect rack-mount parts perpendicular to each other.
  
  
• Single-level connector for CD-profile or "Crab". They are exactly the same, perpendicular CD profiles are connected. If the load is more than 20 kilograms, then two self-tapping screws will be needed for fastening. Otherwise, the seals are simply bent.
  
• Direct suspension for rack (bearing) profile. This is a bracket, the standard length of which is 12.5 cm. It looks like a strip of aluminum or galvanized steel, with holes. Withstands loads up to 40 kilograms. It is attached to the wall with two dowel-nails, then the edges are bent and frame parts are already attached to them.
  
  
• Anchor hanger for ceiling carriers. Often referred to as a suspension with traction. Replaces the part described above if it is not long enough. Used on horizontal surfaces, for ceilings, for example.
  
  
• Extension. Needed to connect two carriers to each other. It has tubercles on the sides, this is the designation of the profile joining point. There are also two holes for screwing screws.
  
• Corner connector. They connect elements that do not form a cross. You can do without a connector. Cut off the shelves of the profile to be connected so that a tongue is formed, and fasten with self-tapping screws.
  
  

Hardware for fixing drywall.

Self-tapping screws are needed to connect all the frame parts and to install drywall. They also come in different types.

Tips on how to choose a profile and accessories for drywall.

1. Carefully inspect the profile before buying. If you notice rust, then you should refuse to buy such material. Once corrosion has already begun, it cannot be stopped!
2. Check the thickness with a caliper. If it turns out to be insufficient, then during operation, the screws will scroll.
3. Do not take a profile with burrs. In the process of work, injure your hands.
4. Take a closer look at the product from the end. If it was stored incorrectly in the store, then it may be bent. With such a profile, you will no longer be able to create a perfectly flat surface of the structure.
5. Keep in mind that in the profile, where the notch is weak, self-tapping screws will be difficult to screw in.
6. Experienced builders are advised to double-check whether the dimensions correspond to those stated in the instructions and in reality. Some manufacturers deceive buyers, especially about the length, it can be less than expected, by 2 centimeters.
7. The quality of the fasteners should also be checked. Very often come across self-tapping screws with a broken tip or with notches clogged with metal for a screwdriver.
8. Inspect the plastic plugs of the dowels well so that there are no sags, otherwise it will be difficult to drive them into the hole, and sometimes even impossible.
9. Give preference, after all, to a profile with dot perforations along the bar - it is more rigid and resistant to stress. This structure prevents the self-tapping screws from slipping, and makes it possible to screw them in at any angle.
10. Rely on established manufacturing companies such as Knauf and Gyprok. But there are also our, domestic manufacturers who produce a drywall profile no worse.
11. Some sly sellers try to hide defects by painting the profile and adding shine to it. Take a closer look at such options, it may not be possible to buy them at all.
12. The product should not be flimsy and bend when pressed lightly.

And the last tip at the end of the article. Do not save on high-quality profiles and accessories for them. As the famous saying goes: "The miser pays twice." If you purchase a low-quality or damaged profile, then in the end, sooner or later, you will have to redo all the work. Somewhere the sheet will stand up as a “bump”, somewhere the joints will become visible, and somewhere the structure will bend inward. Therefore, choose the material carefully, pickiness here will not be superfluous. Good luck and easy work!

Types of profiles for drywall. Video review.

Various drywall constructions are created using a frame made of metal profiles. They are produced in various shapes, sizes and purposes. To determine the desired type of profile, you should understand its purpose, dimensions. Drywall product types are designed for their specific application, so you should familiarize yourself with each type individually.

Types of profiles used to create a frame for drywall

Typical types of metal profiles for drywall

Installation of a frame base made of metal profiles is simple in design. It consists of verticals and horizontals that make up metal elements, which are called guides, ceiling, partition profiles. For the correct choice of the desired profile, you should familiarize yourself with its marking and dimensions.

What are the profiles for drywall:

What are the main profiles for drywall are?

Purpose and characteristics of the guide profile (PN)

Guide profile, abbreviated PN aka UW. Thickness 0.55-0.8 mm. This protects the product from oxidation of the metal, as well as from damage to its rust. In appearance, the PN is made in the form of a plank with the letter “P”, which is used in the construction of a metal skeleton for false walls. It is used for the rapid construction of partitions of various thicknesses. The guides serve as the basis for mounting the frame, creating structural strength. The profile has a different width, which allows you to build high partitions and hide communications in the wall.

Guide profile, suitable for frame for plasterboard false wall

Dimensions of the guide element for drywall:

Holes of 8 mm can be made in the profile by the manufacturer. for fixing the product to the base (wall, ceiling). Fasteners are mainly dowel-nails 6/40, 6/60 in size. The length of the product reaches 3 meters.

In the installation of the partition, the alignment of the wall with drywall, this type of metal product is first attached according to the markings made in advance. Then PS (rack-mount) is applied, as well as additional materials, such as suspensions, extension cords, crabs.

Designations and dimensions UD profile

Rack Profile Functionality (PS)

It stands for stand-up profile, briefly PS or another European designation CW. This type of metal strip is used in the production of a metal frame for a false plasterboard wall, as well as for leveling vertical surfaces in a room. Carrying out the construction of a frame for a false wall, a metal element is inserted into a fixed NP. In this regard, the width of PS and PN has the same dimensions. Partition profile for drywall is made of galvanized steel.

The rack profile is applicable for creating a plasterboard partition frame

Depending on the structure being created, the required size is acquired. The length can be from 3 to 4 meters. A distinctive feature of the profile are special grooves for ease of installation of drywall sheets, as well as their fixation.

CW profile dimensions

Application, dimensions of the ceiling guide profile (PNP)

It is also designated as PN (UD) (decoding - ceiling guide profile). U-shaped in cross section, with smooth sidewalls. It is used as a base-support for racks and lintels. It is attached along the perimeter of the structure, then all other elements of the system are installed into it. PNP is made from metal coated with a protective layer. It is used in the production of a metal base for a false ceiling made of plasterboard. This element is attached to the wall with dowel-nails, serves for further insertion of the ceiling profile into them and creates the strength of the entire structure for drywall.

The ceiling guide profile creates a metal structure for a false ceiling made of plasterboard

The profile for plasterboard ceiling has the following dimensions: thickness PNP 28 * 27 - 0.4-0.6 mm., Width 28 mm., Height - 27 mm., Length - 3 meters.

Ceiling profile (PP)

Please, the most popular in every repair is a ceiling profile (PP) or another designation CD. This product is used in the installation of a metal frame for a suspended, figured, multi-level plasterboard ceiling. The profile is inserted, during installation, into the guide and attached to the hangers. Manufactured from galvanized steel to resist rust. For the ceiling profile, the “bugs” called by the masters are applicable - the diameter is 3.5-3.9 mm. length 9.5-11mm.

The ceiling profile is mounted in a false ceiling frame

The dimensions of the ceiling profile for drywall: thickness 0.4-0.6 mm, width - 60mm, height 27mm, standard length 3 meters on order 4 meters.

Additional types of profiles

And also types of drywall profiles are produced, which are not used so often in the construction of a metal frame, and are mainly replaced by manual production itself.

The arched profile is suitable for creating a frame of arches from plasterboard, as well as figured elements for drywall

Manufacturers offer their own options for bending a profile for arches to order, which has distinctive ease of use. For this, ordinary PP (60x27) is used, after bending it is designated as PA.

Bend radius dimensions:

Curved profile

This element is designated UA. The product is used to strengthen the frame base for drywall. It is applicable in false ceilings of complex design, as well as in the formation of partitions with weighting of objects (hanging a TV on the surface of the partition), creating door and window openings in plasterboard partitions.

The reinforced profile is mounted in the places of the frame, where heavy objects are supposed to be hung on a plasterboard base

Dimensions of the reinforced profile for drywall:

To protect outside corners

PU marked. This type for GKL is intended for sheathing corners from various mechanical influences (impact) of a plasterboard product. The profile is perforated for better fixation to the surface when using putty. It has the following dimensions:
