How long is the corrugated sheet? Corrugated sheet - dimensions and weight of standard sheets for roofs and walls. Dimensions of corrugated sheets for a fence

Today, one of the most popular roofing and facade building materials is corrugated sheets, the sizes and colors of which are available in wide range. In this article we will tell you why corrugated sheeting has become so popular and how it differs from similar building materials on the market.

1 Advantages and disadvantages of different brands of corrugated sheets

Over the years, the profiled sheet has proven itself well. It is worth noting the following advantages of corrugated sheeting:

• simple and quick installation;
• corrosion resistance;
• low weight and high strength;
• aesthetic appearance;
• low cost.

The corrugated sheet consists of:

• base – steel sheet;
• zinc and phosphate anti-corrosion coatings;
• polymer and primer coatings.

The profile sheet has its own markings, by which you can find out what type of work it is intended for. There are three main types of building materials:

1. Wall or facade with product marking “C”, used for finishing areas with small external load.
2. Universal “NS”, suitable for any external and internal finishing.
3. Roofing “N”, designed primarily for the construction and finishing of the roof.

Sometimes manufacturers change standard markings to ones developed specifically for their logos, for example MH, PC, as indicated in the technical specifications for these products.

2 What are the standard parameters of profiled sheets?

The generally accepted and most in demand in construction are the dimensions of rolled metal that provide the greatest convenience during transportation and the least labor intensity during the installation process. TO standard sizes profiled sheets include:

• material length;
• overall (overall) and usable width;
• sheet thickness;
• height;
• sheet weight;

Typically the most popular lengths are 3 and 6 m. The uniqueness of the material lies in its manufacture from roll type metal, therefore, at the request of the customer, the length of the product can be almost any. But with a length of more than 12 m, some properties of corrugated board may be lost.

For different types assembly, it is customary to purchase sheets taking into account the nuances of the structures being built. It must be remembered that the total and working widths differ by an average of 50 mm due to the technology of laying products “overlapping” (overlapping one wave). Therefore, to calculate optimal quantity When transporting the material, the overall width is taken into account; during installation, the working width is taken into account.

The thickness of the corrugated sheet corresponds to the thickness source material– galvanized sheet. The standard material is considered to be from 0.5 to 1 mm.

The choice of wave height (stiffening rib) depends on installation options and the expected mechanical load on the building material; the weight of the sheet and its working width are also taken into account. Naturally, the strength of roof corrugated sheeting will be higher than that of wall sheeting, because the loads it can withstand are many times greater.

3 Corrugated roofing sheet - dimensions of sheets for the roof

The profile sheet began to be widely used for roofing work, thanks to its advantages over ondulin and tiles - lighter weight and high strength, which are provided by stiffening ribs. Corrugated roofing sheets, the sheet sizes of which are the same for all manufacturers, comply with generally accepted GOST or approved technical specifications(THAT). These standards allow the use of this building material for any type of building: industrial buildings, temporary objects, large-sized buildings.

The distinctive dimensional characteristics of the roofing material are the thickness of the metal and the height of the stiffener. Taking these indicators into account, there are several popular brands for roofing:

1. PC 20 with ribs height 20 mm, total width 1140 mm.
2. PC 35, where the height is 35 mm and the total width is 1125 mm.
3. NS 44 and PK 45 with wave heights of 44 and 45 mm, respectively, and a total width of 1045 mm.
4. H57 – height 57 mm and width 1050 mm.
5. H75 – 75 mm and 800 mm, respectively.

For all these brands, profile sheets of various lengths are produced. Depending on the configuration of the floors and the roof itself, lengths from 0.3 to 12 m are used. Also, in addition to the total width, this building material has another important indicator - the working width (less than the total to 50 mm, depending on the size of the profiled sheet).

The external load that the material must withstand directly depends on the thickness of the sheet used coiled steel. The thicker the sheet of metal and the higher the wave (rib) of stiffness, the greater the load the material can withstand. Roofing corrugated sheets with a thickness range from 0.4 to 1 mm is in greatest demand.

This value is taken into account when designing buildings and significantly expands the scope of application of the building material. A load table specially created for design engineers facilitates calculations, which affects the price of the project, significantly reducing its cost. The thickness of the corrugated material affects another important technical characteristics profiled sheet - sheet weight.

Small specific gravity building product became one of the reasons for its popularity.

4 Wall corrugated sheet - dimensions and weight of rolled profiles

And facades are used for cladding buildings, creating a layer of insulation and internal partitions. The most common is corrugated sheet, the dimensions of which are as follows: sheet width 1–1.2 m and wave height about 20 mm (for grade “C”).

The thickness of the metal sheet varies from 40 to 80 mm. The smallest rib height produced on this moment– 8 mm. Wall corrugated sheeting is designed for exterior finishing walls and interior works. There are also materials with fin heights of 10, 15, 17 and 21 mm. Sheets with ribs over 21 mm are considered universal. By individual order some companies produce corrugated sheets less than 8mm thick.

The popular and useful width for walls is considered to be 1090–1150 mm, and the C15 brand is popular in a width of 0.8 m. The latter is often used for. Wall corrugated sheeting weighs much less than roofing sheeting. This figure varies from 4.45 to 8.37 kg for both 1 linear meter and a square of usable area.

The manufacturability of constructing fences for wall or roof structures largely depends on the size of the corrugated sheet, because it matters how many elements will have to be laid to cover the surface: 10 or 20. The other side of the issue is the multiple of the overall dimensions of a single sheet of length and width roof slope, length and height of the fence being constructed. Here, size compatibility greatly influences the amount of trimming.

According to the method of processing steel, hot-rolled steel is distinguished a metal sheet and cold rolled products - both of these types are galvanized or with polymer coating and painting. The coating is applied to both sides or one of them. To produce corrugated sheets, the method of cold profiling using a powerful press is used. Another original type of product is metal tiles.

The main use of bent planes is in construction: wall cladding, fencing areas, laying roofs and installing poured concrete floors on corrugated sheets. The dimensions of the sheet vary depending on the height of the wave - according to this criterion, 3 main types of products are distinguished:

1. Wall- they are distinguished by their smaller thickness and bending of trapezoids (from 8 to 21 mm), and lower load-bearing capacity. Fine corrugation allows you to obtain a larger width of corrugated sheeting during production: a 1250 mm belt goes under the press, and final size determined by the height of the trapezoids. They are used mainly for arranging fences and cladding walls of frame metal structures.
2. Roofing or universal sheets have waves of 20–100 mm. This assortment is most often used for installation on the roof.
3. Load-bearing profiled sheets. The dimensions of sheets versus wall sheets are significantly narrowed, since the trapezoids are larger - from 75 mm and above 100. Scope of application - the manufacture of containers, the construction of garages, hangars: wherever structures are subjected to significant loads.

When purchasing corrugated sheeting, you need to pay attention to the fact that each manufacturer uses its own equipment, and the profile design in detail may not coincide with the trapezoid of another manufacturer. Therefore, it is not advisable to split the purchased number of sheets into 2-3 doses.

The main characteristics of corrugated sheets are encrypted in the product labeling. The designation begins with a letter:

• C - wall;
• NS - universal, or roofing;
• N - carrier.

Some manufacturers use the signs MP, MK in their names. For example, the dimensions of a profiled sheet for a roof under the MP-20 brand mean that the height of the trapezoid is 20 mm. The traditional encryption of the same product looks like C20. A few more numbers follow, giving full information about the dimensions of the corrugated sheet for the fence: width and length - the last two, and before them the thickness of the original stamping metal. Example notation wall covering with a ridge height of 10, a base of 0.50 mm and dimensions in plan of 1x11 meters: C10−0.50−1000−11000.

There is also marking according to an outdated standard, which indicated the coating material. Letter designations AC - aluminum-zinc coating, AK - aluminum-silicon coating and EOTS - electrolytic zinc coating.

For corrugated sheets, like any flat object, the main characteristics are length, width and thickness. An additional parameter taken into account when choosing is the height of the protrusion or wave of the profile. Roofing and wall corrugated sheets are produced in the following standard sizes:

The characteristics of some professional sheets popular among the population are shown in the table.

As you can see, heavy sheets with a corrugation height greater than 75 mm are not in demand. Wall corrugated and load-bearing sheeting are in demand for the greatest width.

Profiled sheet - modern, beautiful, durable and durable material for the roof. For accurate calculation required quantity For this coating, you need to know the length, width and thickness of the sheet. In addition, information about the weight and load on the roof is needed. This will make it possible to correctly make rafters and other roof elements, as well as select a grade of corrugated sheeting that corresponds to the operating conditions in the construction region.

Dimensions of roofing sheets

The main parameters of a profiled sheet are its length, width, thickness and profile height. All characteristics of profiled sheets are determined in GOST 24045–94.

Sheet length and width

There are total and useful lengths and widths of corrugated sheets:

• The total length and width are the distance between the edges of the sheet. The length can vary from 3000 to 12000 mm (multiples of 250 mm), width - from 800 to 1800 mm. At the request of the customer, the length of the sheet can be made less than 3000 mm and more than 12000 mm;
• useful length and width of the sheet is full size minus the overlap size. The length of the sheet is chosen so that it is equal to the length of the slope plus the size of the eaves overhang (200–400 mm). If you use shorter sheets, the material will have to be laid with an overlap, which will reduce the level of waterproofing of the roof. Thus, when the total and useful length of the profiled sheet coincide, this the best option. The overlap in width is usually one wave.

Sheet thickness and profile height

Corrugated sheeting with a thickness of 0.55-1.0 mm is suitable for roofing work. Thinner metal will warp when exposed to snow, wind or hail. It can also be accidentally damaged during installation.

The profile height can vary from 8 to 75 mm. If a wall sheet, which, for example, can be used to build a fence, may have a profile height of 8 mm, then corrugated sheeting with a value of at least 20 mm is used to construct the roof.

The roofing corrugated sheeting has a wave height of 20 mm, and at the joint there is often a capillary groove on it to remove moisture

Types of profile and its markings

Distinguish the following types corrugated sheets:

• wall It is used for cladding cabins, warehouses, car washes (indicated by the letter C);
• roofing (N or PC). Used to cover roofs;
• universal (SN). Suitable in both cases;
• carrier. It is used for the construction of structures operating under heavy loads, and, like roofing material, has a high profile height. Therefore, roofing corrugated sheeting with a large thickness of metal can be used as a load-bearing material.

Next to the letter there is usually a number indicating the height of the profile. Examples of such designations: S-18 (wall corrugated sheet with a wave height of 18 mm), N-75 (roofing material, wave height of 75 mm), NS-60 (load-bearing corrugated sheet with a wave of 60 mm).

Brief marking of the corrugated sheet contains data on its type and wave height

However, there is also more detailed marking, for example: N-57–750–0.8 AD ML-1202/ML-1203, where:

• N - purpose of the material (roofing);
• 57 - profile height;
• 750 - sheet width;
• 0.8 - its thickness;
• the further sequence of numbers and letters indicates the type of applied polymer coating. IN in this case This is double-sided spraying with different characteristics from each side. Sometimes, instead of information about the polymer coating, the length of the sheet is indicated.

Table: characteristics of some types of corrugated sheets

Brand	Purpose	Characteristics
		Height profile, mm	Thickness, mm	Full/ useful width, mm	Length, mm
S-21	Wall profiled sheet, sometimes used for roofing arrangement. It has good rigidity. Corrugation trapezoidal.	21	0,4–0,8	1250/1000	up to 12000
S-44	Wall profiled sheet, quite often used for roofing. In combination with frequent lathing and a steep roof slope is quite suitable for roofing work.	44	0,65–0,8	1250/1000	up to 14500
NS-35	Universal profiled sheet, used for roofing arrangement.	35	0,4–0,8	1250/1000	up to 14000
NS-44	Universal profiled sheet, used for roofing works	44	0,55–0,8	1250/1000	up to 13000
N-57	Used as roofing material and as a load-bearing profiled sheet	57	0,6–0,8	1000–1250/ 750–900	up to 13000
NS-60	Universal professional sheet. Has high rigidity and strength. Is good roofing material.	60	0,65–0,9	1250/845	up to 14000
N-75	Roofing and load-bearing professional sheet with the best profile height indicators and metal thickness. Stable to the snow and wind.	75	0,7–0,9	800/750	up to 12000

When purchasing corrugated sheeting, it should be taken into account that the greater the height of the profile, the smaller the width of the sheet.

Despite the fact that in the practice of roofing work they use different materials, experts advise choosing profiled sheets NS(N)-60, N-75, NS-35. They have special stiffening ribs and are most suitable for roof protection.

The corrugated sheet can simply be galvanized or coated with a protective polymer coating. Polymer coating makes the sheet more resistant to impact weather conditions and increases the durability of the roof.

Calculation of the size and number of corrugated sheets for roofing

Let us remind you that the useful length of a corrugated sheet is optimal option equal to its full length. Therefore, to calculate required quantity sheets there is no need to calculate the roof area and divide it by the sheet area. This is done much simpler: the width of the slope with a correction factor must be divided by the useful width of the metal profile sheet.

Let's calculate the number of sheets required for roofing for a regular pitched roof.

A pitched roof allows you to most simply demonstrate the algorithm for calculating the number of corrugated sheets required for a roof

For example, let’s take a roof with a roof slope width of 12 meters and calculate the required number of sheets of NS-35 grade corrugated sheets.

1. Multiply the width of the slope by correction factor 1.1. This is necessary to take into account overhangs, waste and the possibility of damage to the sheets during transportation and installation. We get 12 ∙ 1.1 = 13.2 m.
2. To determine the number of sheets, divide the resulting value by the useful width of the sheet. Since the useful width of the NS-35 sheet is 1 meter, we divide 13.2 by 1 and get 13.2. The result is rounded to big side and we understand that to arrange the roof we need 14 sheets.
3. We count the amount of corrugated sheeting in square meters. This will be useful for determining the cost of roofing material. We multiply the number of sheets by the length of the sheet (for example, 6 meters) and by the full width of the sheet (for sheet NS-35 it is 1.25 meters). We get: 14 ∙ 6 ∙ 1.25 = 105 m 2.

For gable roof A similar calculation must be carried out for each slope. If the slopes are the same, then the resulting value for one of them just needs to be multiplied by 2.

If two sheets or more are laid along the length, the calculation is made slightly differently:

1. Calculate the roof area. The slope has the shape of a rectangle, so its area will be equal to the product of the sides: S = 12 ∙ 6 = 72 m 2 (the transverse size of the slope together with eaves overhang taken equal to 6 m).
2. We multiply the roof area by a correction factor of 1.1. We get S = 72 ∙ 1.1 = 79.2 m 2.
3. Divide the resulting value by usable area leaf. Let's assume that sheets with a length of 3.5 m are used. Then the useful length will be equal to 3.25 m (we set aside 25 cm for the longitudinal overlap). We calculate the useful area as the product of this value and the useful width (1 m): S floor = 3.25 ∙ 1 = 3.25 m 2.
4. We calculate the number of sheets, why total area divide the roof by the usable sheet area: N = S / S floor = 79.2 / 3.25 = 24.37. This means we will need 25 sheets of corrugated sheets measuring 3.25 x 1.25 m.

Produce advance paynemt roofing material can also be done using one of the online calculators, of which there are quite a few on the Internet.

The relationship between the type of corrugated sheet, the angle of inclination of the roof and the maximum pitch of the sheathing

Specifications different types profile determine its use for roofs with certain angles of inclination and pitch of the sheathing.

Table: influence of the profile type on the roof slope angle and sheathing pitch

Marking	Tilt angle roofs	Maximum step battens
S-20	up to 15 o	Solid
	more than 15 o	50 cm
S-21	up to 15 o	30 cm
	more than 15 o	65 cm
S-44	up to 15 o	50 cm
	more than 15 o	100 cm
N-60	more than 8 o	3m
N-75	more than 8 o	4 m
NS-35	up to 15 o	50 cm

Profiled sheets marked “C” are cheaper than other brands. Therefore, they are often used for roofing. However, it is still better that in this case the angle of inclination of the roof is 45 o or more. With such a slope, the snow will melt quickly and water will not penetrate inside through the joints. In addition, when using sheet “C” for the roof, the sheathing must be made frequent or continuous.

Roof sheet weight

The weight of the roof is one of the most important indicators, which should be taken into account when arranging it. It determines the pressure exerted by the roof on the rafters and load-bearing walls. When carrying out calculations, it is convenient to operate with the weight of one square meter material. Then, knowing the total area, you can calculate the weight of the entire coating.

To the greatest extent, the weight of the profiled sheet is determined by the following factors:

Calculation of the weight per square meter of profile sheet

The weight of a polymer-coated corrugated sheet consists of the weight of metal, zinc and polymer.

To carry out the calculation we need some initial data:

• steel density - 7.85 t/m 3;
• zinc density - 7.12 t/m3;
• polymer density - 1.5 t/m3;
• polymer coating thickness - 0.05 mm (pural).

Table: thickness of zinc coating of metal sheet depending on class

Coverage class zinc	Thickness coating, mm
1	0,0381
2	0,0216
Z-100	0,0208
Z-140	0,0212
Z-180	0,0260
Z-200	0,0297
Z-275	0,0405

The calculation is made according to the formula: M = t ∙ l ∙ h ∙ p, where t is the thickness of the material, l is the length, h is the width, p is the density.

For example, let’s calculate the weight of a metal sheet with an area of ​​1 m2 and a thickness of 0.8 mm with a galvanized coating of class Z-200 and a polymer coating made of pural:

• the weight of a square meter of metal without galvanized coating thickness is 0.8 ∙ 1 ∙ 1 ∙ 7.85 = 6.28 kg;
• the weight of galvanized coating class Z-200 is 0.0297 ∙ 1 ∙ 1 ∙ 7.13 = 0.21 kg;
• the weight of the polymer coating made of pural is 0.05 ∙ 1 ∙ 1 ∙ 1.5 = 0.08 kg.

Adding up all the results, we get 6.57 kg.

Overall weight per square meter roofing sheet is in the range of 5.4–12.4 kg, but most often it falls within the range of 6.0–8.0 kg.

Calculating the weight of a roofing sheet using a table

The weight of the required grade of corrugated sheeting can be quickly found in special reference tables.

Table: weight per square and linear meter of profile sheet depending on the brand

S21–1000	0,55	5,9	5,9
S21–1000	0,7	7,4	7,4

You can compare the weight per square meter of corrugated sheeting with other roofing materials. It is almost one and a half times lighter bitumen shingles and four times lighter than slate.

Corrugated sheeting is one of the lightest roofing materials- it is almost four times lighter than slate

Weight of roofing pie covered with corrugated sheets

The approximate weight of 1 m2 of materials that make up the roofing pie is:

• corrugated sheet - 6 kg;
• hydro- and vapor barrier from polymer membrane- 1.5 kg;
• insulation from mineral wool- 10 kg;
• sheathing made of boards 2.5 cm thick - 15 kg.

Adding up all the given data, we get 32.5 kg. We use a correction factor of 1.1 - specific gravity roofing pie will be 35.75 kg. Of course, it may vary slightly depending on the weight of the components, but when standard thickness load-bearing walls and rafters can withstand loads of up to 250 kg/m2. Thus, with average weight values ​​of roofing materials, we have a more than sevenfold safety margin.

Strength characteristics of corrugated roofing

The roofing material must be durable, that is, it must withstand loads under certain operating conditions without collapsing or deforming. Corrugated sheeting is much stronger than flat sheet metal of the same thickness. This happens due to the presence of a certain profile in this material. A profile with a higher height can withstand greater loads. For example, for wall corrugated sheet C10–1200–0.6 with a support spacing of 1 meter permissible load is 86 kg/m2, and for sheet NS44–1000–0.7 with a distance between supports of 3.5 meters - 182 kg/m2. Profiled sheet H75 makes it possible to create a gap between the supports of 5–7 meters and has no restrictions on snow load. Reducing the number of supports allows you to save material for their arrangement and make it easier rafter system. However, sheets with a high profile height are made from thicker metal, so they are heavier.

Maximum permissible loads

There are 4 options for constructing corrugated sheet supports: one-, two-, three- and four-span. The width of the support at the point of contact with the corrugated sheet must be at least 40 mm.

When constructing roofs they can be used different schemes fastening corrugated sheets with a number of fixing points from one to four

Calculation of the strength of the roofing covering and selection of the grade of corrugated sheet

The total load on the corrugated sheet consists of snow and wind pressure, as well as the weight of the decking itself.

For example, let's take the following data:

• gable roof;
• the angle of inclination is 35 o;
• the size of the projection of the slope onto the horizontal surface is 6 m;
• the weight of a square meter of corrugated sheeting is 7.4 kg (this is the indicator of sheet C21-1000-0.7). In terms of the load on the rafter system and load-bearing walls, as well as the price, it is quite suitable for us, but its strength remains to be determined;
• construction is underway in the Moscow region.

The specific snow load is determined using a special map issued by the hydrometeorological center. The entire territory of our country is divided into 8 snow regions. In each of them, the standard snow load is considered the same.

The snow load map allows you to determine the snow pressure on the roof in different regions of Russia

Table: value of standard snow loads by region

The construction site is located in the third snow region. The specific snow load here is 180 kg/m2. Taking into account the type of roof and the angle of inclination, the load is calculated using the formula 180 ∙ (60 o - a)/a, where a is the angle of inclination of our roof. It turns out 180 ∙ 25/35 = 128.6 kg/m 2.

Specific wind load for the roof is determined in a similar way. For this, there is another map, which also divides the territory of Russia into 8 regions.

The snow load map allows you to determine the wind pressure on the roof in different regions of Russia

Table: value of standard wind loads by region

In terms of wind load, the Moscow region is in the first wind region, where normative meaning equals 32 kg/m2. Taking into account the slope of the roof, the coefficient aerodynamic drag will be equal to 0.3. Thus, the wind load on the roof in question is 32 kg/m2 ∙ 0.3 = 9.6 kg/m2.

We calculate the total load on the roof. It is equal to the sum of the weight of the materials of the roofing pie, wind and snow load: W = 7.4 + 128.6 + 9.6 = 145.6 kg/m2. From the above table of strength characteristics, you can see that for the roof in question, corrugated sheet C21-1000-0.6 with a maximum load of 195 kg/m2 is quite suitable. However, we do not recommend using corrugated sheets with minimal acceptable characteristics, but to make a greater margin of safety, since there are situations when there is much more snow than usual, and the winds have a strength that significantly exceeds the standard values.

The method for calculating the number of sheets of corrugated sheets discussed in the article allows you to use the material economically and reduce the cost of arranging the roof. Characteristics various brands profiled sheets make it possible to choose exactly what is needed for your building. Calculating the weight of the roof and its strength will make your roof reliable and safe for many years.

When preparing a series of articles dedicated to modern building materials We couldn’t ignore corrugated sheet metal as a super popular wall cladding or roofing metal sheet. Despite its deceptive simplicity, many questions arise regarding the characteristics and features of the profiled sheet, even among those who work with it professionally. Let's finally take a closer look at the brainchild of the English engineer Henry Palmer, who is credited with inventing the profiled sheet back in 1820.

Kinds. What does it consist of and where is it used?

The profiled sheet is made from rolled sheet steel with different heights corrugation, thickness, width and length of the sheet. Profiling the steel base provides rigidity to the profiled sheet without increasing weight, and galvanic treatment provides an attractive appearance and protection against corrosion.

Designation of corrugated sheets (for example, C25-0.60-700-11,000) contains all the information on its main characteristics.

The letter indicates the scope of application:

N- load-bearing roofing sheet.

WITH- wall for walls and fences.

NS- load-bearing wall material for universal use.

The number is the profile height in millimeters.

The next one is the thickness of the metal, which was used for stamping the sheet, in mm. GOST 24045-2010 This product is made from thin galvanized steel GOST 14918.

The third means the installation width of the corrugated sheet, mm.

Transcription examples

Example 1: C 21-1000-0.7

C - wall profiled sheet with a profile trapezoid height of 21 mm, a working width of 1000 mm and a metal thickness of the original blank made of rolled galvanized steel of 0.7 mm

Example 2: C 21-0.55-750-12000

C - for wall fencing with a trapezoid profile height of 21 mm, made of metal 0.55 mm, with dimensions: 750 x 12000 mm

Today you can still find markings in accordance with the previous GOST (more about the regulatory documents below). In the outdated standard, coated sheets contained additional designations:

aluminum zinc ( AC);

aluminized and aluminum-silicon ( A and AK);

electrolytic zinc ( EOTSP).

Application

Profiled sheets are used for:

Construction of the roof;

Installation of floors (including steel-reinforced concrete);

Construction of wall fences.

Current GOST

Active normative document on steel profiles- this is GOST 24045. Over time, changes are made to the standards and the following common versions exist of this document:

GOST 24045-86, status: replaced;

GOST 24045-94, status: replaced;

GOST 24045-2010, status: valid.

According to the material of the initial workpiece, steel profiles according to GOST 24045-2010 have one category: thin-sheet galvanized steel according to GOST 14918.

By previous version GOST galvanized sheet contained the following number of subcategories:

galvanized rolled sheets GOST 14918;

rolled sheets with aluminum-zinc coating (designated AC) according to TU 14-11-247-88;

sheets of aluminized rolled stock and rolled sheets with aluminum-silicon coating (designated A and AK) according to TU 14-11-236-88;

rolled sheets with electrolytic zinc coating (designation EOTSP) according to TU 14-1-4695-89.

Main dimensions of the metal profile

For roofing

U roofing type wave height is 2 and more, see. Moreover, the profile can be complex shape, which provides additional rigidity to the product.

According to sales statistics of construction hypermarkets, consumer choice is C 44 And H57 750. The latter was taken as a basis in GOST 24045-94 in calculations bearing capacity roofs.

The sheets can be of any length. Roofing material brand H57 width is 75 cm, H60 - 84.5 cm, H75 - 85 cm. The carriers and roofing sheets corrugation height is 3.5 - 4.4 cm. Thickness of the brand product "N" equal to 0.6 - 0.9 mm.

For the fence

As can be seen from the table above, almost every type is suitable for installing fencing and the key selection criterion is usually the economic considerations of the owner.

The fence type has a low ridge height and thickness. Sheet C10 equal in width 90 - 100 cm, C18, C21 and C44 - 100 cm. Wall finishing sheets have a width of 1.3 cm. Then the height of the corrugation of each subsequent type will increase by 3.25±0.25 mm. Sheet grade “C” is the lightest and thinnest - 0.5 - 0.7 mm.

How much does it weigh

The type of sheet greatly influences its weight. As the “wave” of the profile and sheet thickness increases, the mass increases. Weight is the main advantage of this product. On average it 1 m2 weighs 7 - 11kg. If this area is covered with tiles, then it will be needed 43 kg. Weight 1 m2 stamp sheet "WITH" equals 5.5 - 7.5 kg.

There are special tables in which the mass is shown as a function of the brand, thickness and width of the sheet 1p. m.. or 1 m2 material. To calculate the weight of the decking, you can also use one of the weight calculators that can be easily found on the Internet.

Patterns and texture of decorative profiled sheet

The drawing on the sheet is printed on polymer material and under the influence of temperature they are sintered with the metal, forming a shell that protects the metal and the image.

The drawings are panoramic and continuous. This material is used, in addition to fences, for finishing the basement or the entire building (profiled sheet to look like stone, wood, brick, etc.).

Example decorative covering under the tree

An example of a decorative stone coating

An example of a decorative brick coating

New technologies protect images from fading in the sun and external environment. According to the manufacturers, the design will not fade 15 years.

Coloring of profiled sheets

Of course, works of art like this please the eye and awaken a sense of beauty, but a cold mind mercilessly steps on the song’s throat and demands that the issue be resolved in the style of Tom Sawyer, and most likely “yesterday.”

Like other leaf parameters, its color is standardized. The most famous color standard is the scale RAL.

Today it includes 213 colors and each has a 4-digit digital code. This makes it easier to select the color of products regardless of the manufacturer.

Usually only the front side of a profiled sheet is painted. But on request they are also produced with double-sided painting.

Colors according to RAL scale

The photo shows an example of painting a fence in colors according to the RAL scale

Very convenient to order material desired color without visiting the construction site. We point our finger at the color we like, call the manager and call the unique code from the table. Then all that remains is to meet Gazelle with the material on your site.

What you need to know if you do it yourself

What to cut

The material can be cut perfectly with ordinary metal, electric or with a hand jigsaw, hacksaw, grinder.

Hole Punching Tool

You can always hack something with a hammer and improvised tools. But anyone who has held a specialized tool in their hands at least once is unlikely to refuse it. We bring to your attention special hole-punching pliers Ø 10.5 mm in sheet thickness up to 1.2 mm under brackets for ventilation, drainage, etc.

This easy-to-use tool makes installation easy thanks to its opening width and adjustable grip depth. Typically, pliers have a set of replaceable punches.

Seals for profiled sheets

Their production goes into wood-polymer composite, polyethylene foam and polyurethane foam. They copy the wave of the leaf and prevent moisture, dust and insects from getting into the cracks.

Since the seal has porous structure, it does not interfere with air circulation and the removal of moisture from under the roof, as well as the settling of condensate from below the covering.

There are different types of seals:

self-adhesive universal (soft) - suitable for all types of products with waves up to 20 mm;

special types used for this type leaf.

What is the best way to mount it?

Self-tapping screws

To attach sheets to the sheathing, use pneumatic or electric drill. The self-tapping screws are tightened observing the tightening torque. Their average cost for installing flooring is 5 - 6 pcs/m2.

Rivets

As can be seen from the comparison picture, fastening with rivets using construction pistol looks more aesthetically pleasing.

The flooring is fastened with special rivets for these products, since the use of other rivets leads to poor-quality fastening and shortens the service life.

Rivet diameter ( 3.2 - 6.5 mm) is selected according to the thickness of the sheet. This fastener is made from special aluminum and galvanized steel.

For structures made of profiled sheets, where design is important, colored fasteners can be used.

Conclusion

The subject of our conversation touches on a huge range of works that cannot be covered in one article. We tried to give useful links on related materials, in addition, articles are planned in the series of publications that will deeply reveal all the issues related to the use of profiled sheets. We will be glad if you add the site to your bookmarks and come back to check them out.

In addition, we will be grateful for constructive criticism, suggestions and your questions, which can be asked via the contacts indicated on the page >>>

Corrugated sheeting is by far the most common type of roofing materials. Corrugated sheet sizes depend on two parameters: the wishes of the customer and the purposes of use. The material is steel sheet wave-shaped with a special polymer coating.

Corrugated sheet size

The material is used in the construction of roofs, fences, wall cladding, creating a frame for non-residential premises etc. This material used for both external and internal lining, this is allowed.

Metal profiles - sizes and types of sheets:

• N - load-bearing, roofing corrugated sheeting. The height of the sheet corrugation is more than 44 mm. This corrugated sheet is characterized by increased resistance to mechanical stress and rigidity. Thanks to this, it has found its use in the construction of supporting and load-bearing structures, floors and roofs.
• C - wall corrugated sheeting. Due to the smaller height of the corrugation (from 8 to 44 mm), it does not have such high rigidity indicators. Therefore, this type of corrugated sheet is used as a facing material.
• NS - load-bearing wall, universal corrugated sheeting. The height of the corrugation is 35-44 mm. It has good rigidity indicators, and therefore can be effectively used both for creating walls and fences, and for installing roofs.

Typically, corrugated roofing is used - the dimensions of the sheet do not exceed 4 meters. At large values length, the sheet becomes inconvenient to work with.

Length and width of metal profile

Corrugated sheet length can be completely different, since it is made from rolled steel. Therefore, this dimension depends on the needs of the customer. When taking into account not only the length of the roof slope itself, but also the overhang of the canopy.

Typically, corrugated sheets are used, the sheet width of which ranges from 980 to 1850 mm. In this case, it is worth distinguishing between the useful and actual width of the sheet. Thus, the useful width, due to the installation of overlapping corrugated sheets, is always 4-8 cm less than the real one.

The purpose of the material is no less important. Thus, a metal profile whose dimensions are 2.4-12 meters can be used for absolute number tasks in construction. Standard sizes metal profiles are used for roofs of large buildings - this allows the profile to be laid in a certain order, thereby achieving high levels of tightness and excellent appearance of the roof.

How to choose corrugated sheeting, see the video for details:

Metal profile - thickness and height

The thickness of metal profile sheets directly affects the strength of the material - the thicker it is, the greater the load the material can withstand. The standard thickness of corrugated sheeting is 0.5 and 0.55 mm; sheets with a thickness of 0.7, 0.8 and 1 mm are also available (read: ""). When determining required thickness sheet for construction, you should start from the area of ​​the object being built and possible loads (also read: "
