Profiled sheet sizes. Dimensions of corrugated sheets for roofs and fences. gost. weight. marking. Strength characteristics of corrugated roofing
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 steel processing, 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:
- Wall- they are distinguished by their smaller thickness and curved trapezoids (from 8 to 21 mm), lower bearing capacity. Fine corrugation makes it possible to obtain a larger width of corrugated sheeting during production: a 1250 mm belt goes under the press, and the final size is determined by the height of the trapezoids. They are used mainly for arranging fences and cladding walls of frame metal structures.
- Roofing or universal sheets have waves of 20–100 mm. This assortment is most often used for installation on the roof.
- 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. Next follow a few more numbers that provide complete information about the dimensions of the corrugated sheet for the fence: width and length are the last two, and before them is the thickness of the original stamping metal. An example of the designation of a 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 manufactured 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.

Corrugated sheets are called corrugated (profiled) sheets of galvanized steel. This material is very widely used in construction. It is excellent for wall cladding, roofing, construction of panel fences and frame structures. And this is only a small part of the work where corrugated sheeting can be used - the dimensions of the material allow you to choose the optimal value for any conditions.
There are several main areas of use of corrugated sheets:
- fence/wall;
- carrier;
- roofing
Wall corrugated sheeting has dimensions such that it can be easily installed on a wall or on supports to create a fence. The wave height of the corrugated sheet is small, and the steel base is also the smallest compared to other types of material. In view of this, wall corrugated sheeting is used where the load on the surface will be small - in barriers, wall partitions, suspended ceilings. In the construction of industrial facilities, wall corrugated sheets are used for finishing vertical surfaces and walls. Due to its low height, the material is highly economical. It is very important that the metal profile can be used several times.
The group of wall profiled sheets includes the following brands:
- MP40.
Roofing corrugated sheets are distinguished by a higher profile sheet height - 20 mm or more. The dimensions of corrugated roofing may vary depending on the needs of a particular construction. Due to the presence of additional stiffening ribs, this type of material has greater strength. Roofing corrugated sheeting is used for arranging roofs, structures, hangars, fences, pavilions and stationary fences. This type includes brands C44 and NS35.
The greatest strength is inherent in the load-bearing profiled sheet. It is made from steel sheet of the greatest thickness. The profile height (corrugation) starts from 44 mm. Thanks to these factors, the load-bearing profiled sheet can withstand heavy loads. Therefore, it is used for arranging permanent formwork and floors. This group includes brands H60, H75, H114.
Corrugated roofing sheeting - dimensions
Profiled sheet C8
Profiled sheet C8 has following parameters:
- total width - 1.25 m;
- usable width – 1.15 m;
- profile height (corrugations) - 8 mm;
- base sheet thickness - 0.5 or 0.6 mm.
This type of material is one of the most economical. Its popularity is explained at an affordable price and excellent performance characteristics (more details: " "). The advantages of C8 grade profiled sheet include reliability, durability and ease of installation.
The distinctive features of the brand include the low profile height and incredibly convenient sheet width. C8 is used for the construction of temporary structures and installation of fences. This type of corrugated sheeting is also used for wall cladding and suspended ceilings.
Due to its low weight, the profiled sheet can be used for mounting structures on top of light frames (more details: " "). This contributes general decline costs for carrying out installation work. The low profile height helps to minimize space loss, which becomes especially important when interior decoration walls and surfaces. Well, these sheets are not particularly difficult.
But it should be understood that C8 corrugated sheeting cannot be used to cover the roof (read also: ""). Low rigidity will not allow this material to effectively withstand loads. Only temporary roof covering is allowed during repair work. And yet, the main area of use for C8 corrugated sheets is the creation of fences.
Profiled sheet C21
The profile of sheet C21 has a trapezoidal shape. Standard parameters The lengths for this brand of corrugated sheeting are considered to be 2, 3 and 6 meters, which is what it is designed for.
Corrugated roofing dimensions:
- total width - 1.05 m;
- usable width - 1 m;
- corrugation height - 21 mm;
- sheet thickness - from 0.4 to 0.7 mm.
Profiled sheets of this brand are used in the following areas:
Profiled sheet C44
Roofing corrugated sheeting has the following parameters:
- total width - 1.47 m;
- usable width - 1 m;
- profile height - 44 mm;
- base thickness - from 0.5 to 0.8 mm;
This one has additional stiffening ribs. If we also take into account the fact that the thickness of corrugated roofing C44 is much greater than other types of roofing, then it becomes immediately clear that this brand is intended for creating structures that must withstand significant static and mechanical loads.
Most often, C44 corrugated sheeting is used for:
Profiled sheet NS35
This corrugated sheet has the following dimensions:
- usable width - 1 m;
- total width - 1.06 m;
- sheet thickness - from 0.5 to 0.8 mm;
- profile height - 35 mm.
When choosing sheet roofing material First of all, its operational properties are taken into account - strength, durability, resistance to loads and external influences. The features of installing the flooring and the requirements for the sheathing are also taken into account. The dimensions of corrugated roofing affect a number of key parameters. In addition, the number of decking joints depends on the dimensions of the sheet - the fewer there are, the more airtight and durable the roof covering. Format sheet material is selected taking into account the size of the slopes - this allows to minimize the amount of waste.
Roofing sheets
Features of manufacturing profiled sheets
Corrugated sheets are formed using special equipment from high quality sheet steel. The cold pressing method allows you to give the sheet a special configuration by extruding protrusions in a wavy, trapezoidal or rectangular shape. Thanks to the resulting relief, the sheet material acquires the necessary rigidity and the ability to withstand increased loads.
Profiled sheets are a popular material in civil and industrial construction. It is used for cladding structures, installing permanent formwork, erecting fences and arranging roofs. Each type of work has its own requirements for the characteristics of sheet material.
An example of laying flooring without joints along the length The main parameters of corrugated sheets, including those brands that are suitable for roofing work, include the length and width of the sheet, its total and effective area, metal thickness, relief characteristics (wave pitch and height, its configuration).
Sheet material dimensions
For profiled sheets, a standard has been developed in Russia - GOST 24045-94 (Bent steel sheet profiles with trapezoidal corrugations for construction), which strictly regulates the dimensions of the corrugated sheet and other parameters of the material, including the thickness of galvanization. If the product characteristics comply with GOST, the material can last the entire service life specified by the manufacturer.
Length
Rolling mills, which are used for the production of corrugated sheets, are designed to produce sheet material up to 14 meters long. Profiled sheets of standard dimensions are widely available on sale - they have small sizes, convenient for independent transportation and installation.
Roofing corrugated sheets are produced by serious enterprises and small companies. If you plan to purchase locally produced material, it is recommended to order the production of profiled sheets, the length of which corresponds to the length of the slope. This will allow:
- create a more reliable coating - its tightness and durability are higher than that of a roof made of small sheets, since there are no horizontal joints of elements;
- reduce the cost of roofing by reducing the amount of material (there are no overlaps of elements), quick installation, minimum amount of waste.
It should be taken into account that if the sheet length is more than 6 meters, delivery of corrugated sheeting to the site will cost significantly more than transporting material of standard dimensions, since you will have to rent special equipment. Long profiled sheets are noticeably more difficult to lift onto the roof due to their large dimensions and weight. Requires the use of lifting equipment.
Lifting long profiled sheets When producing profiled roofing sheets to order, the equipment is configured in such a way that cutting sheets to the specified size is carried out automatically. The adjustment system allows you to change the length of the sheet in the range from 500 mm to 14,000 mm with a cutting step of 500 mm.
Width
Rolled thin sheet steel, which serves as a material for the manufacture of corrugated sheets, has standard width 1250 mm. But after processing on a rolling mill, the width metal element changes due to the formation of corrugation.
The width of the corrugated sheet depends on the profile configuration and wave height. For example, the width of the C8 wall corrugated sheet with slight corrugation is 1200 mm, and the width of the H75 load-bearing corrugated sheet is only 800 mm, although the products are made from rolled steel with standard parameters.
Please note that the dimensions of the corrugated sheet have two width parameters. The total (geometric) width of the sheet is the distance between its edges, which can be easily measured with a tape measure. There is also a “working” (also known as “useful”) sheet width - this parameter indicates how much of the roof slope in width will be covered by the sheet, taking into account lateral and transverse overlaps. For C8 corrugated sheets, with a geometric sheet width of 1200 mm, the useful width is 1150 mm.
Main dimensions of the material The side overlap is one or two waves, in accordance with the loads on the roof and the characteristics of the rafter system. An overlap of two waves is required when installing roofs with a small slope angle; this increases the tightness and strength of the deck.
When calculating the flooring for roofing covering, proceed from the working width of the sheet material, otherwise you may not have enough of it later.
Thickness
When choosing a profiled sheet for a roof, you need to pay attention to such a parameter as the thickness of the metal. To manufacture this type of material, rolled steel can be used, the thickness of which is 0.45 - 1.2 mm. Durability depends on this indicator roofing– the thicker sheet metal, the stronger it is and the longer it resists corrosion.
When discussing the optimal option, it should be taken into account that sheet profiled material up to 5 mm thick does not tolerate mechanical loads, so it requires frequent or continuous lathing.
Characteristics of profiled sheet NS-44 Sheets with a thickness of 0.7 mm or more are strong and durable, but the weight of such material is noticeably higher. Accordingly, this complicates installation and increases the load on rafter system. A roof made of thick corrugated sheets requires reinforced supporting structure, which, in turn, will add loads to the walls and foundation.
This means that the use of roofing corrugated sheets with a thickness of 0.7 mm or more must be provided for at the building design stage or used only as a replacement for heavy coatings during repairs or reconstruction. An increase in the thickness of the corrugated sheet leads to an increase in the cost of construction.
The optimal thickness for roofing material made of profiled steel is considered to be 0.5-0.6 mm - a coating made from such sheets can cope with high wind and wall loads, the cost of the material is affordable, and the weight is relatively light. Durability depends on the quality of galvanization and the characteristics of the external protective and decorative layer. Material that complies with GOST will last for several decades.
Profile Features
Corrugated roofing sheets must withstand atmospheric and operational loads and actively remove moisture falling on the roof. These properties are largely determined by the height and configuration of the profile. The higher the wave, the greater the load the material can withstand.
When assessing the configuration, pay attention to the presence of additional longitudinal stiffeners - such material is more resistant to high loads. Stiffening ribs on sheets with a trapezoidal profile are located on the edges of the trapezoids or between the bases. Material with increased longitudinal rigidity can be mounted on flat roof, during installation pitched structures it is allowed to increase the sheathing pitch.
Profile with increased longitudinal rigidity To equip the roof, a load-bearing corrugated sheet (H) or a universal sheet (NS) is used. For light canopies, the use of wall canopies (C) is allowed.
A specialized roofing sheet differs from a conventional load-bearing sheet by the presence of a capillary groove, which is located on the edge of the sheet, which is overlapped on top by an adjacent element. The capillary groove removes moisture that has penetrated under the flooring.
Characteristics of some popular profile brands If the roofing sheet is made of steel thinner than 0.5 mm, the edge of the capillary groove is easily deformed during loading or unloading, during lifting of the material onto the roof and installation. In this case, the groove cannot perform its function, and moisture gets inside the roofing pie.
To purchase required amount roofing material, it is necessary to perform appropriate calculations, which take into account the surface area of the slopes, the roof structure, as well as the type of profile and its corresponding standard sizes corrugated sheet.
Calculation of sheet length
If corrugated roofing is chosen as a covering, the size of the sheet and the price of the material must be indicated in the design and estimate documentation along with its brand.
Ideally, the length of the sheet should correspond to the dimensions of the slope, so that each strip does not have to be assembled from several elements. This coating is more resistant to stress and leakage. But it should be taken into account that it is difficult to lift a profiled sheet more than 6 meters long onto the roof and secure it without deforming it.
If you decide to purchase standard format material for laying the roof, you need to calculate how many sheets it will take to install one strip. Calculations are carried out using the formula N=(A+B)/D, while
- A – slope length;
- B – length of the edge of the sheet, which should protrude beyond the edge of the cornice (5-10 cm);
- D – length of the profiled sheet;
- N – number of sheets.
- C – overlap length (from 15 to 20 cm, exact value indicated by the manufacturer).
- Then the resulting values (N and N1) are summed and rounded to the nearest whole number.
Calculation of sheet width
To calculate how many sheets of corrugated sheets will be laid along the width of the slope, you need to divide the width of the slope (horizontal length) by the useful width of the roofing sheet. To the result obtained, add 50 mm to the eaves projections. For every slope complex roof the calculation must be performed separately.
Installation of profile on the roof It is rational to use large cuttings for installing coverings on other areas of the roof. In this case, on each of the slopes the sheets are mounted in only one direction, and the trim may turn out to be symmetrical and cannot be installed due to the difference in the size of the lock flange. This should be taken into account when designing and calculating the roof covering.
Conclusion
Corrugated sheeting, the dimensions of which depend on the grade of material and the choice of element length, is easy to install and practical material for roofing. Without taking into account the dimensions of the profiled sheet for the roof, it is impossible to correctly design the roof and purchase optimal quantity material.
If you decide to make a fence from corrugated sheets around suburban area or a private home, it will be useful to familiarize yourself with tips on how and which one to choose corrugated board for a fence.
Behind Lately profiled sheet has evolved from an inconspicuous galvanized bent metal profile into an attractive material with a wide range of color shades, textures and configurations. And this is just what lies on the surface.
How to choose corrugated sheeting for a fence? Which is better or worse? What parameters of corrugated sheeting are decisive for a fence? Is it possible to use corrugated roofing sheeting on a fence? We will consider these and other questions within this article.
The first thing to consider is the parameters of the fence itself:
- length;
- height;
- frame.
These are the three pillars on which all further calculations of corrugated sheeting are based and have a direct impact on the choice.
Second, determine the duration of operation
The service life (temporary or permanent) is an important point, which, along with the fence itself, will determine the installation budget. The cost of a fence made of corrugated sheets may depend on the fencing parameters, which are difficult to change, and on the price of the corrugated sheet, which is determined by the quality of the metal profile (which in turn affects the estimated service life of the fence).
From this point of view, a corrugated sheet fence can be temporary (fencing construction site) or permanent (fence near the house). The longer the fence’s service life is expected, the more scrupulous you need to be in choosing it.
Which corrugated sheeting for a fence is better to choose?
To make a choice and use the right material, you need to evaluate the main parameters:
1. Corrugated sheet covering
Like any metal, corrugated sheeting, which has an iron core at its core, is subject to corrosion processes. To slow down the process of rust or prevent it, the corrugated sheet is covered with special coatings, the type and thickness of which determines the cost and service life of the corrugated sheet.
There are two types of corrugated sheets on the market, each of which has varieties:
Without decorative coating
3. Thickness of corrugated board for the fence
The most controversial of the parameters. The fact is that the thickness of the corrugated sheet directly affects the strength of the fence.
What thickness of corrugated board should I choose for the fence?
Sellers advise purchasing thicker metal - 0.5-1 mm. However, craftsmen and many users agree that a reliable frame can compensate for the small thickness of the corrugated sheet. From the point of view of cost and labor intensity of work, this is a controversial issue, but the fact that a durable frame is able to level out the windage of a sheet and gives it rigidity is unambiguous.
Therefore, the most optimal thickness for users is 0.45. Taking into account the permissible deviations in GOST 24045-2010 and EN 10143 of +/- 6 mm. in fact it is 0.39 mm. However, professional installers provide a guarantee for a fence with such corrugated sheeting.
How to check the thickness of corrugated sheets?
The seller is obliged to provide all sheets for thickness measurement. Regarding the thickness zinc coating, there are three options here - either take the seller’s word for it, or demand documents for the coil of metal from which the corrugated sheet is rolled. Again, you need to remember that the documents can be for one bay, and the rental is made from another. The third option is to send the sample to a laboratory for analysis. But installing a fence made of corrugated sheets with your own hands is not such a large project as to waste resources on analysis.
4. Color of corrugated fence
Color does not affect the strength characteristics of the fence, but it determines the visual appeal and affects the price of corrugated sheeting.
All manufacturers (except Ruukki (Finland), which use the RR color layout) use the standard Ral table for color designation. Thanks to this, corrugated different manufacturers designed in one color scheme.
What color to choose for corrugated fence?
The question is rhetorical, but according to statistics, among the favorites are 8017 (brown), 3005 (rotten cherry), 6005 (green), 6002 (light green).
Today, a popular solution is to use corrugated sheeting coated with printech with patterns like wood, brick, stone, etc. Printech imitation corrugated sheeting looks very advantageous in the finished product. And the decor, in the form of columns, posts or forged parts, only gives the fence solidity and prestige.
Note. It is important to know that any coating is exposed to ultraviolet radiation, i.e., it fades. But, high-quality coating burns out evenly. In terms of speed, this process can be compared to the fading of paint on a car. However, if the sheet is replaced, the difference in shades may be noticeable. Even purchasing a sheet “just in case” will not save the situation.
Glossy or matte corrugated sheeting is another point that determines appearance fence The matte surface looks more noble, but it loses its attractiveness after rain, because... dirt from the soil settles on the surface of the fence. It is advisable to place such sheets on a foundation or constantly clean them. The point is not the attractiveness of the fence, but the fact that fine particles dirt increases the rate of destruction of the sheet coating.
To choose the right profiled sheet for a fence, you need to pay attention to a few more nuances:
- leaf appearance. Large deviations in width and length (above the permissible GOST 19904-90) should alert you when purchasing (substandard);
- front surface quality. Peeling of paint, blistering, stretching, scratches - all this will lead to destruction of the surface and inevitable corrosion. Dents do not cause any particular harm to the corrugated sheet, but they also do not decorate the appearance of the fence;
- cut quality. Typically, the length of the sheet is set at the profiling stage. The guillotine cuts the metal sheet smoothly, without nicks. Using a grinder or other cutting tools results in an uneven cut - this is a direct path to the appearance of rust at the cutting site;
- overlapping wave geometry. It should fit perfectly onto the wave of the previous sheet. There is no need to believe the seller’s statements that the sheet will be pressed with an additional screw. A sheet screwed to the sheet, and not to the frame, will not hold the self-tapping screw, and installing additional support or joists is costly;
- presence of film. It is not a mandatory attribute, but will protect the sheet from damage during transportation;
Advice. After installation of the corrugated sheeting is completed, the film must be removed. Once it dries to the surface, the film is practically impossible to remove.
- availability of guarantee and other accompanying documents.
Note. If the calculation of the amount of corrugated sheeting is carried out by the seller, he must provide a layout diagram of the sheets. This is especially important when roofing work, as well as during the construction of a fence of complex configuration.
Taking these factors into account will help make right choice fence corrugated sheeting and avoid the situation shown in the photo.
Agree, this is a convincing example of why you shouldn’t save money on purchasing profiled flooring.

Price of corrugated sheeting for a fence
Based on the foregoing, we can conclude that the price of corrugated sheeting is an objective value that is determined by the thickness, type of coating and quality of the finishing layer of the sheet. Corrugated sheeting, the cost of which is lower than the market price, by definition cannot be of high quality.
Advantages of a fence made of corrugated sheets
- strength;
- maintainability;
- almost any shape;
- relatively low cost;
- resistance to bad weather and mechanical damage;
- beautiful appearance and the ability to combine with other materials (goes well with stone).
In addition, it is possible from corrugated sheets, since it is not demanding in installation and maintenance.
