The profiled material for the roof will correspond to the manufacturer's declared operational properties provided that all installation requirements are met. The quality of roofing work directly depends on how the dimensions of the corrugated sheet for the roof are optimal for this design. We will introduce you to the types of sheet roofing, indicate what functions are affected by its dimensions, and why you need to choose not only according to the size of the sheet, but also according to its thickness.
Profile dimensions and roof quality
The roof provides comfort for the whole house. When choosing its coverage, you can not make mistakes. What is meant by the right choice roofing material:
profiled sheet size for the roof provides a minimum number of transverse and lateral joints;
sheet weight does not create an additional load that requires strengthening the foundation;
corrugation type corresponds to the type of crate, the shape of the roof;
technical, operational specifications profiles are optimal for climate conditions and expected roof loads;
appearance coatings organically fits into the design of the building, the overall ensemble of the site.
All these points are satisfied with the roof of corrugated board. This roofing material characterize such qualities:
small weight;
decorative yet protective outer coating metal profiles;
ease of installation and the possibility of carrying out "patching" repairs;
wide choose sizes and colors.

What is corrugated board and profiled sheet
According to GOST, corrugated board includes cold-rolled metal sheets with wavy stiffening ribs. Galvanized steel is used most often, but there is a profile of aluminum, copper, chromium-nickel steel. Manufacturers offer sheets with waves of oval, trapezoidal, square, polygonal shapes.
A coating based on zinc and aluminum is used to protect the metal from corrosion. By applying additional layers of polymers (polyester, teflon, a mixture of PVC, PVDF, pural, plastisol), strength, wear resistance, and color brightness are increased.
According to the manufacturing technology, the profiled sheet does not fundamentally differ from the corrugated board. It has reinforced ribs. The size of the profiled sheet is more suitable for roofing.
Strength, bearing capacity of any type of profiled material determined by the following:
thickness;
width;
corrugation type;
number of stiffeners.
Marking and types of corrugated board
Marking "NS", "MP" or roofing. Profile corrugation height starts from 8 mm, additional stiffening ribs are formed. Such a sheet of corrugated board can have a thickness of 0.55 to 0.8 mm, weight from 6.3 to 14.5 kg / m2. It has a high resistance to mechanical stress. Suitable for various types of roofing work.
Marking "C" or wall profiled sheet. Types, sizes and colors may vary. The base thickness does not exceed 0.7 mm. The weight of 1 m2 varies between 5.4-7.4 kg. Well established as a facade finish. In roofing work, the wall sheet can be used for peaks, roofs in outbuildings.
Marking "H" or bearing. It has the largest thickness, reinforced stiffeners. The weight of profile sheets up to 1.2 mm thick can reach 24 kg/m2.
The marking contains not only letters, but also numbers indicating the size of the corrugated board:
first digit after letter height waves;
second - width;
the third is the maximum length profile.
Each type of corrugated board is suitable for use as a roofing material, depending on the roof design and performance requirements.
Roof sheet length
The maximum length of corrugated roof decking is limited by the possibility of a rolling mill and does not exceed 14 m. This size allows you to minimize the number of sheet joints and increase the strength of the entire coating. Rarely, the length of the roof slope is much more than 14 m, which means that there will be no more than 2 horizontal joints.
The high price and the difficulties of transporting long sheets brought to the top corrugated board 6 m long. But you can order any option, depending on design features roofs. The minimum length is 0.5 m. The range is a multiple of 0.5 m and varies from 0.5 m to 14 m.
Experts pay attention to the fact that the more joints, the more useful material is lost. Each connection of metal profiles is made with an overlap of 20 cm.
Roof sheet width
The technical specifications indicate two sizes of profiled sheets for the roof in width:
geometric or "from the manufacturer", which is simply measured with a ruler;
worker, which determines the area of the covered surface without taking into account the "waste" for installation.
According to the requirements of tightness and strength, the lateral overlap cannot be less than one wave. For a roof with a small angle of inclination, a sheet of corrugated board with an overlap in two waves is mounted.
The table shows the data on the width of the corrugated board:
| Profiled brand | Geometric width, mm | Working width, mm |
| C8 | 1250 | 1150 |
| C21 | 1050 | 1000 |
| HC35 | 1060 | 1000 |
| MP20 | 1150 | 1100 |
The difference in the width of the metal profiles shows how much more it is necessary to purchase a sheet for the roof than the roof area.
Popular forms of corrugated board
Mostly found on the market the following forms corrugated board:
wave sheet for a roof with a cross section in the form of a sinusoid. It has a low bearing capacity. Externally, a roof covered with such a profiled sheet will resemble a tiled one. Scope of application: light roofing.
Corrugation in the form of a trapezoid, it combines ease of installation, high rigidity, and a large bearing capacity. Scope of application: all types of roofing works.
Profiled sheets with corrugation letter "P"(cassette) - by technical specifications it is more used as a wall.
The dimensions of the metal profile for the roof include the height of the profile. The most rigid options have a greater height, and the greater the rigidity, the higher its technical and operational characteristics. Minimum height 8-12 mm, maximum 35-65 mm.

Conclusion
The profiled sheet for the roof is selected according to size, thickness, type of coating, type of corrugation. All this can be learned from the marking, which is always available from manufacturers who value their reputation. The knowledge gained in the article will help you to make right choice so that the roof is always a reliable protection for the hearth.
The manufacturability of erecting fences for wall or roof structures to a large extent depends on the size of the profiled sheet, because it matters how many elements have to be laid to cover the surface: 10 or 20. The other side of the issue is the multiplicity of the overall values of a single sheet, the length and width of the roof slope, the length and height of fence. Here, size compatibility greatly affects the number of cuts.
According to the method of processing steel, hot-rolled metal sheets and cold-rolled products are distinguished - both of these types are galvanized or polymer-coated, painted. The coating is applied on both sides or one of them. For the manufacture of corrugated sheet, a cold profiling method is used with a powerful press. Another original type of product is a metal tile.
The main application of bent planes is in construction: wall cladding, territory fencing, roofing and poured concrete floors on corrugated board. The dimensions of the sheet vary from the height of the wave - on this basis, 3 main types of products are distinguished:
- Wall- they are distinguished by a smaller thickness and bending of the trapezoids (from 8 to 21 mm), a lower bearing capacity. Fine corrugation makes it possible to obtain a large width of corrugated board during production: a 1250 mm tape goes under the press, and the final size is determined by the height of the trapezoids. They are mainly used for arranging fences and wall cladding of frame metal structures.
- Roofing or universal sheets have waves of 20–100 mm. This range is most often used for laying on the roof.
- Bearing profiled sheets. The dimensions of the sheets against wall sheets are significantly narrowed, since the trapezoid is 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 board, you need to pay attention to the fact that each manufacturer uses its own equipment, and the profile pattern in detail may not coincide with the trapezoid of another manufacturer. Therefore, it is undesirable to split the purchased number of sheets into 2-3 receptions.
The main characteristics of the corrugated sheet 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 the name. 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 profiled sheet for the fence: the width and length are the last two, and in front of 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 terms of 1x11 meters: C10−0.50−1000−11000.
There is also a marking according to an outdated standard, which indicated the coating material. Letter designations AC - aluminum-zinc coating, AK - aluminum-silicon and EOCP - electrolytic zinc coating.
For corrugated board, as for 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 profile wave. 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 of more than 75 mm are not in demand. Wall corrugated board and load-bearing are in demand for the greatest width.

The professional flooring is the most widespread type of roofing materials today. Profiled sheet dimensions depend on two parameters: the desire of the customer and the purpose of use. The material is a wave-shaped steel sheet with a special polymer coating.
Decking sheet size
The material is used in the construction of roofs, fences, wall cladding, creating a frame for non-residential premises, etc. This material is used for both external and internal cladding, this is allowed.
Metal profile - sizes and types of sheets:
- N - bearing, roofing corrugated board. The height of the corrugation of the sheet is more than 44 mm. Such a corrugated board is characterized by increased resistance to mechanical stress and rigidity. Thanks to this, it has found its application in the construction of supporting and load-bearing structures, ceilings and roofs.
- C - wall corrugated board. Due to the lower height of the corrugations (from 8 to 44 mm), it has not so high rigidity indicators. Therefore, this type of profiled sheet is used as a facing material.
- NS - bearing-wall, universal corrugated board. 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 mounting roofs.
Roof decking is usually used - the sheet dimensions of which do not exceed 4 meters. At large values length with a sheet becomes inconvenient to work with.
The length and width of the metal profile
Profiled sheet length can be completely different, as it is made of rolled steel. Therefore, this dimension depends on the needs of the customer. When take into account not only the length of the roof slope itself, but also the overhang of the visor.
Usually used corrugated board whose sheet width ranges from 980 - 1850 mm. In this case, it is worth distinguishing between the useful and real width of the sheet. So, the useful width, due to the installation of overlapping corrugated board, is always 4-8 cm less than the real one.
No less important is the purpose of the material. So, a metal profile whose dimensions are 2.4-12 meters can be used for an absolute number of tasks in construction. Standard sizes of metal profiles are used for roofs of large buildings - this allows you to lay the profile in a certain order, thereby achieving high tightness and excellent appearance of the roof.
How to choose corrugated board, in detail on the video:
Metal profile - thickness and height
The thickness of the metal profile sheets directly affects the strength of the material - the larger it is, the greater the load the material can withstand. As a standard, the thickness of corrugated board is 0.5 and 0.55 mm, there are also sheets with a thickness of 0.7, 0.8 and 1 mm (read: ""). When determining the required sheet thickness for construction, one should start from the area of \u200b\u200bthe object being built and possible loads (also read: "
Profiled sheet is one of the most common building materials used for roofing and finishing works, for the construction of fences and the construction of frame structures. These are corrugated sheets of galvanized metal, which may or may not have a polymer coating. Knowing the dimensions of the corrugated board for the fence, you can choose best option for a particular type of work.
Profiled sheet - a versatile material with a wide range of colors
Different types of metal profiles differ in many parameters. The following dimensions are usually indicated: corrugation height, total sheet width, working width, metal sheet thickness.
Profiled sheet marking
All types of corrugated board are divided into 3 categories, depending on the purpose. They are denoted by different letters:
- C - wall profiled sheet, intended for all types of facing works, as well as for the construction of fences. Differs in affordable cost and reliability. The wave is raised by 4-44 millimeters.
- H-roofing profiled sheet. Able to withstand significant pressure loads. The height of the corrugation is more than 44 millimeters.
- HC is a universal profiled sheet that can be used for any work. The corrugation can have a rise of 35-44 millimeters.
It cannot be said that the professional sheet for various purposes has standard sizes. Different brands of products differ in their dimensions and other characteristics. For example, the dimensions of the profiled sheet for the fence will be different from the dimensions of the roofing corrugated board.
As examples, we will analyze the most popular and affordable types of metal profiles, such as C8, C10, C20, C21, indicating their features and sizes.
Dimensions of corrugated board grade C8
C8 is considered one of the most economical options. It is widely used for the construction of temporary structures, fences, sheathing wall surfaces. Due to the low height of the corrugations, C8 can be used for filing false ceilings. Sheets do not take up space from the internal volume of the room. The light weight of the C8 sheet makes it possible to use light wooden frames. This reduces the cost of construction.
For roofing work, C8 profiled flooring is not recommended due to its insufficient rigidity.
C8 sheet dimensions:
- Overall width - 1.2 meters;
- useful (working) width - 115 cm;
- corrugation height - 8 mm;
- wave pitch between adjacent ribs - 115 mm.
Other types of wall corrugated board can be used for roofing, subject to certain conditions.
The size of the profiled sheet for the fence grade C10
This is a galvanized sheet with a small wave height, which allows you to create complex design and design solutions.
Scope of profile sheet C10:
- Finishing work on wall structures.
- Buildings are sheathed with C10 material inside, they are made dropped ceilings.
- As temporary fencing at construction sites and other facilities.
- C10 sheets are used for construction.
If sheet C10 is used as a roof element, then it is necessary to ensure a significant angle of inclination of the roof. This is necessary in order to avoid possible weight loads in the form of snow, which could push through the metal profile.
The size of the profiled sheet for the fence C10 C10 dimensions:
- Overall width - 1.16 meters;
- metal profile thickness - 0.4-0.8 mm;
- corrugation height - 10 mm;
Dimensions of profiled sheet brand C20
Dimensions of corrugated board S-20 These are durable sheets of galvanized metal, in the section having the shape of a trapezoid or wave. It is used in various areas of construction:
- For roofing work. The step of the crate when using C20 should be no more than 40 cm.
- C20 is used for the manufacture of sandwich panels.
- Manufacturing of rigid structures. As a basis for mounting C20, a reinforced profile should be used.
- Sheathing of walls of buildings, garages, hangars, workshops and other buildings.
- Arrangement of partitions inside buildings.
- C20 is used for the manufacture of reliable fences.
Sheet dimensions C20:
- Overall width - 1.15 meters;
- useful (working) width - 110 cm;
- thickness of the metal profile - 0.45-0.7 mm;
- corrugation height - 18-20 mm;
- wave pitch between adjacent ribs - 137.5 mm.
Dimensions of profiled sheet C21
Dimensions of corrugated board C21 These are sheets of a trapezoidal profile. Standard sheet lengths are 6, 3 and 2 meters. Despite the fact that this profiled sheet belongs to the category of wall materials, its scope is much wider:
- Cladding of walls and facades of buildings.
- The construction of fences from C21 allows you to create durable and rigid structures.
- C21 allows you to build lightweight buildings using frameless technology.
- Installation of a roof with a sparse crate. C21 panels have a high corrugation, therefore they have an increased load-bearing capacity. It is used for any slopes of a roof.
- High-quality sandwich panels are made from C21 sheets.
- Sheathing of wooden structures, pavilions, garages, outbuildings.
- Beautiful and durable fences are being built from C21, including fences for industrial enterprises.
Sheet dimensions C21:
- Overall width - 1.051 meters;
- useful (working) width - 100 cm;
- metal profile thickness - 0.4-0.8 mm;
- corrugation height - 21 mm;
- wave pitch between adjacent ribs - 100 mm.
Whatever type of profiled sheet you choose for your needs, first find out their dimensions in order to make a structure with a minimum amount of waste. Purchase corrugated board with a margin of about 1 running meter, since the sheets will overlap each other. You may need a margin of more than 1 meter if, for example, a long fence is being built.
The most popular roofing material is profiled sheet. To obtain a high-quality result, the dimensions of the corrugated board play an important role. After all, the market offers an extensive range of such materials. Therefore, it is worth understanding this characteristic in more detail. The article will consider the dimensions and characteristics of the profiled sheet, its application.
Decking is a corrugated sheet made by rolling on a roll forming machine. With the help of such processing, wavy, trapezoidal or rectangular protrusions, called waves or ridges, are obtained on its surface. The profiled sheet is made from rolled steel coated with zinc. The scope of such material is very extensive: the construction of fences, wall cladding, roofing, etc. 
The main characteristics of profiled sheets are regulated by GOST 24045–94. Materials produced in accordance with this standard are of higher quality. There are advantages to using profiled sheets, such as:
- ease of transportation and installation;
- resistance to corrosion;
- durability;
- dimensions under individual order;
- thermal stability;
- ease;
- variety of assortment;
- moisture resistance;
- reusable;
- high strength.
Corrugated sheet length
One of the characteristics of a metal profile is its length. During installation, such sheets are overlapped. Because of this, 200 mm or more of their length is lost. In accordance with SNiP II-26-76, the size of the overlap must be over 250 mm. It is better to use corrugated board with dimensions corresponding to the dimensions of the roof of the building. Namely, the length of the slope. This will allow installation without horizontal joints, and increase the tightness of the coating.
The standard size of the material is from three to ten meters. This value should be a multiple of 0.5 m. On modern rolling machines, it is possible to produce a profiled sheet whose size is 14 meters. Due to high shipping costs, these sheets are made to order only. 
Metal profile thickness
The next important characteristic for a profiled sheet is its thickness. The strength and durability of the roofing depends on it. The larger this parameter of the profiled sheet, the higher the indicated characteristics will be. Decking is made from galvanized sheets with a thickness of 0.45–1.8 mm. When choosing a material, it is important to consider that, in addition to the undeniable advantages, thick sheets also have disadvantages. Large sheet thickness leads to an increase in cost installation work and complexity of assembly. In addition, the price of a metal profile depends on the thickness of the profiled sheet. The higher this figure, the higher the cost.
Corrugated sheet width
An important characteristic is such an indicator of corrugated board as the width of the sheet. It is used to calculate the roof device. The width of the sheet depends on the height of the corrugation. The lower the wave, the larger the described dimensions of the metal profile. Sheets of standard sizes are produced in widths of 845–1850 mm.
When performing calculations required material for the roof, it should be noted that this characteristic of the corrugated sheet has two values. One is complete, the other is working. To ensure tightness, laying sheets with an overlap is necessary. In accordance with SNiP II-26-76, the amount of overlap must correspond to the width of one corrugation. This results in a reduction in overall width of approximately 40–80 mm. 
Surface shape and stiffeners
Roof materials must be resistant to additional loads: gusty wind, ice, hail, snow weight, etc. The reliability of the coating depends not only on the thickness of the corrugated board, but also on the height of the wave. This value can be determined by calculating the distance between two adjacent waves. The lower the crest, the lower the resistance of the profiled sheet to deformation.
At certain types metal profile on the upper surface of the trapezoid and / or between the waves, additional stiffeners can be formed. Due to the presence of such ribs, the longitudinal rigidity of the profiled sheet increases. Due to this, it is possible to increase the step of the crate truss system. Such roofing material is excellent for buildings with significant static loads. 
Varieties of material
Currently, the range of profile sheets is very extensive. According to the area of \u200b\u200buse, the profiled sheet is divided into the following types:- for roofing (bearing);
- for walls;
- universal.
The standard sizes of a professional flooring for walls provide ease of installation work. The features of this type are the smallest height of the corrugation, the manufacture of a thin galvanized sheet. Areas of application of the wall profiled sheet are barriers, suspended ceilings and wall partitions. This type of profile is more economical. For this reason, with limited funds, it is also used to cover the slopes of the roofs of residential buildings. The universal profiled sheet (bearing-wall) has a crest height of 20 to 44 mm. Like the carrier, it has additional stiffeners and is almost as strong as it. Due to the lower metal consumption, its cost is relatively lower. Due to this, the universal metal profile is used more widely. It is used for roofs, sheds, fences, etc. Metal profile marking
As mentioned earlier, to regulate the main characteristics of a galvanized metal profile, a standard has been developed - GOST 24045-94. This normative and technical document introduces marking for profiled sheets. This marking consists of an alphabetic and numeric designation. Where the letter code means the purpose of the profiled sheet, and the digital one - the height of the wave of the metal profile.
Profiled sheet dimensions, described in GOST, have the following marking: - For roof coverings:
- H114, with a width of 600 mm;
- H114, with a width of 750 mm.
- For walls:
- C10;
- Universal:
- HC35;
- HC44.
