For roofing, fencing and cladding of various surfaces, metal profiled sheet is actively used today. Its popularity is due to its reasonable cost and excellent performance. When it becomes necessary to purchase such products, it is important to clearly understand what kind of sheets are needed in a particular situation and in what quantity they need to be purchased.

So that this task does not seem too complicated, we will try to consider profiled sheets in detail, find out what are their differences, and in what area they can be used.

The main characteristics of the profiled sheet, which you need to know when purchasing material

It is immediately worth noting that the metal profiled sheet has several varieties that differ in thickness, size, type of coating, product weight and type of profile. It is these characteristics that determine the scope and performancematerial.

So that the choice of sheets is not carried out by eye, the manufacturer affixes the appropriate marking on each product, which is strictly regulated by the standards and is the same for all manufacturers. It is represented as a letter (C, H, or CH) at the beginning of a line, and several numbers separated by a hyphen.

For example: С18-0, 50-750-1100. The letter indicates the type of product, the first number indicates the height of the rib, the second indicates the thickness of the metal used, the third indicates the width of the profile, and the fourth number indicates the length of the sheet itself. All measurements are in millimeters.

In addition, the letters A and B can be placed on the finished product, indicating its front and back sides. The presence of the letter R indicates that the sheet has a special groove that prevents water from flowing in at the joints of the sheets.

Varieties of profiled sheet

As mentioned earlier, the metal profiled sheet is divided into several groups. Namely:

  • roofing sheets;
  • wall materials;
  • mixed products.

Roofing galvanized profiled sheet is marked with the H mark and is characterized by increased rigidity and strength. For the production of such sheets, thicker metal is used, which significantly affects the cost of production, therefore, this group of materials is most often used for roofing.

The wall profile marked with the letter C has lower characteristics and is usually used for claddingsurfaces, fencing and for the assembly of temporary structures.

Products with the NA mark have average performance and are considered universal. They are actively used in both roofing and cladding.

Differences in profile shape

In addition to technical characteristics, galvanized profiled sheet (including painted) may differ in the shape of the recesses, which significantly affects its rigidity. The profile can be in the form of waves, a trapezoid, or simply be U-shaped.

Products of the latter type are considered to be universal, they are most often used in wall structures. The trapezoidal profile is considered the most durable and has excellent bearing capacity, while the wavy type is lightweight and the most inexpensive.

Differences by type of coverage

The characteristics of the profiled sheet depend not only on the thickness of the metal, but also on the properties of the protective coating applied to its surface. It comes in several types:

  • Polyester. Due to its low cost, this type is the most common. It painlessly tolerates sudden changes in temperature and perfectly resists ultraviolet rays. The brightness of the coating is maintained for a long period of time, but it is not resistant to mechanical stress.
  • Coated polyester. The composition of this material is very similar to the previous version. The difference lies in the fact that the surface of the sheet is rough and does not shine in the sun. Similar sheet options can be made withimitation of wood, stone or brick.
  • Pural. This protective layer contains polyurethane and acrylic. A dense coating reliably protects the sheet structure from damage and the harmful effects of acids, which ensures its long-term operation.
  • Plastisole. This option consists of polyvinyl chloride with the addition of various plasticizers. It is applied in a sufficiently thick layer and reliably protects the metal profiled sheet from most types of negative influences. However, this composition is unstable to temperature fluctuations, which slightly limits the scope of such products.
  • PVDF. This coating is made of polyvinyl fluoride and acrylic. It is applied in a small layer, but reliably protects the sheet from the effects of an aggressive environment. The service life of such products is 35-45 years.

Dimensions of profiled sheets

To assess your financial capabilities and determine the required amount of material for certain works, you need to know the dimensions and prices of the profiled sheet, and if the cost depends on many factors, then the dimensions comply with the standards and are clearly defined for each type.

professional sheet sizes and prices

Bearing and roofing sheets can have absolutely any height, as they are made by rolling. The width usually varies from 75 to 115 cm. The most popular universal options have a fixed width of 100 cm. When ordering a professional sheet in production, you can indicate the desired dimensions of the finished product so that their delivery and installation take placeas convenient as possible.

C8-C10 metal profiled sheet (wall version) is produced no wider than 90-100 cm, and products of the C18-C44 category are exclusively 100 cm.

Height and width of profiled sheet waves

The height of the wave bend directly depends on the type of sheet material. So, for load-bearing options marked with the letter H, this indicator is much higher than for other types and can reach 144 mm. Shallow grooves are additionally located along the product, which makes it much tougher. This allows the use of a metal corrugated sheet on the roof.

profiled sheet gate

The height of the waves of the bearing-wall variety (NS) reaches 44 mm, and the width of the grooves in such variants is 114 mm. The rigidity of this group of profiled sheets is quite enough to use it for both roofing and wall work.

Wall corrugated board has a minimum wave height (from 10 mm), which explains its low bending strength. Nevertheless, the gate from the profiled sheet, the fence and various storage facilities are made from this material, since it is quite light and cheap.

Thickness and weight of profiled sheets

Depending on the manufacturer, the profiled sheet has different sizes and prices, but the weight of the products should be approximately the same. And since the sheets are always mounted on some kind of base, when choosing a facing material, you need to know what load it will have on the crate or walls.

For approximate calculations, we recommend using the following information:

  • Products marked H are characterized by a sheet thickness of 0.5 to 0.9 mm. Based on this, we can conclude that the weight of 1 m² will range from 7.4-11 kg.
  • The thickness of load-bearing wall profiles usually does not exceed 0.8 mm, therefore, the maximum weight of 1 m² is 9.4 kg.
  • The lightest facing materials have a width of 0.5 to 0.7 mm. In this case, the weight of 1 m² of such a sheet will be from 5.4 to 7.4 kg.

Application area of ​​profiled material

The options for using profiled sheet materials are endless, so we will take a closer look at where each type of product with different markings can be used.

A profiled sheet gate, a decorative fence, a small fence and summer hangars are most often assembled from a C-8 or C-10 profile. It is also ideal for insulating the outer walls of buildings.

roof metal sheet

S-20 and S-21 products are used for arranging light coverings (various canopies and canopies), and S-44 material is used for quick surface cladding and roofing.

Professional sheet NS-35 and NS-44 is universal and multifunctional. It can be used for all of the above purposes and for any type of wall construction.

Reinforced H-75 and H-60 ​​sheets are mostly used in industry. They are used to make the basis for a membrane roof, assemble formwork for monolithic ceilings and build industrial hangars.

How are corrugated sheets fixed?

In order for the performance characteristics of the assembled structures to remain at the highest level, it is not enough just to buy high-quality material, it is also necessary to properly fasten the profiled sheet to the base. Various fasteners can be used for these purposes.

profiled sheet fastening

When it comes to arranging roofing, profiled sheet manufacturers recommend giving preference to special self-tapping screws. Their diameter ranges from 4.8 to 6.3 mm, and their length is from 20 to 250 mm. The peculiarity of such fasteners is a wide hexagonal head (with a soldered press washer) and the presence of a special rubber gasket that does not lose its properties even when used in an aggressive environment.

For the arrangement of fences and partitions, you can purchase steel self-tapping screws with a protective zinc coating. In this case, a rubber gasket must be laid between the nail head and the profiled sheet.

Before installing the profiled material, the base should be treated with an anti-corrosion solution. This will significantly extend the life of the entire structure.

Cost of profiled sheet

Depending on the manufacturer, the thickness of the metal and the type of the upper protective layer, the cost of this material may vary significantly. Therefore, we will consider how much the most popular wave profiled sheet with various types of protection will cost.

Thus, a Russian-made galvanized product will cost the buyer about 167 rubles per m². Atthe presence of a polyester protective layer (0.4 mm thick) the same sheet will cost about 220 rubles per m².

The price tag of products with plastisol coating starts at 595 rubles per m², while a profiled sheet with a pural layer is estimated by the manufacturer at 450 rubles.

In conclusion

High technical characteristics, practicality and ease of installation contribute to the fact that the profiled sheet becomes an almost universal material. In addition, it is quite easy to cut, transport, drill and process both manually and mechanically.

Unpretentiousness in operation and long service life make the use of profiled sheets more than relevant, which confirms its active use on most construction sites.
