Corrugated sheet is a metal product used for internal and external construction work. It is a steel sheet with a three-dimensional pattern on one side. The characteristics of the original rolled products are determined by GOST 19903-2015. The dimensions and other properties of corrugated sheets with diamond and lentil patterns are regulated by GOST 8568-77. Rolled steel with lentil and rhombic corrugation has an anti-slip surface, which is important for ensuring the safety of personnel in industrial and agricultural enterprises, in warehouses, and passengers in transport.
Types of relief sheets
Such metal products are produced by hot deformation on mills using rollers, which produce a smooth surface on one side and a corrugated surface on the other. In the mass version, carbon steels St0, St1, St2, St3 of various degrees of deoxidation are used for these products. Rolled products for use in conditions where decorative, hygienic qualities, and corrosion resistance are important, are made from stainless steels AISI 321, AISI 201, AISI 316, AISI 430.
In addition to the material used in production, these sheets differ in:
- the type of riffles and the option of their placement;
- the thickness of the workpiece used for the manufacture of corrugated sheets;
- number of projections per 1 m
2.
Products meet the following requirements:
- the height of the corrugations is 10-30% of the thickness of the original sheet or rolled products; in metal products with a thickness of 5 mm or more, the height of the corrugations must be at least 1 mm;
- the dimensions of the diagonals of the rhombuses are in the range of 25-30x60-70 mm;
- the distance between the lentils is 20, 25, 30 mm.
Corrugated metal sheet dimensions:
- length – 1.4-8.0 m in increments of 50 mm;
- The width of the finished corrugated sheet is 0.6-2.0 m, pitch is 50 mm.

Methods for producing corrugated sheets
Corrugated products are created using the method of hot deformation and cold pressing. In the first case, the steel billet is heated to the required temperature and passed through rollers, one of which has a stencil. Raised bumps are printed on only one side of the sheet. On the other hand, the surface remains smooth.
When using the second method, special presses are used. After processing the workpiece, the corrugations are visible on both sides of the product. On the working surface the image is raised, and on the reverse surface it is depressed.
Finished products are cut on all sides. In accordance with GOST standards, there should be no delamination on the edges of corrugated sheets. Jagged edges are allowed on the rolled edges. They should not extend the sheet beyond the established width dimensions. The presence of traces of mechanical damage on the surface of the products is not allowed. To control technical parameters, one roll or two sheets are selected from the batch
Types of corrugation patterns
Manufacturers offer the following types of patterns:
- "Diamond" . This is the simplest pattern, consisting of grooves that are located perpendicular to each other.
- "Duet" . This pattern differs from the previous one in the double arrangement of riffles.
- "Quartet" and "Quintet" . These are complex designs that have a decoratively attractive appearance.

Sheets with lentil corrugations, made in accordance with GOST standards, are used for finishing building structures, ramps, stairs, paths and bridges. Steel products are used for lining refrigerators and freezers.
For finishing industrial premises, sheets with a thickness of at least 4 mm are used. Products used for exterior and interior decoration are thinner. The rolled products are stored in the cabins of freight and passenger elevators. The use of anti-slip corrugated sheets reduces the likelihood of industrial injuries and prevents accidents.
Weight m2 of sheets according to GOST 8568
In order to calculate the cost of 1 sheet, you need to know the weight of the product of the required cutting. To calculate, we will use data on the theoretical weight of 1 m2 of rolled steel depending on the thickness of the sheets (these values are defined in GOST 8568):

What is a diamond corrugated sheet?
Bumps on metal sheets, which are formed using corrugations, are not a decorative method, although such products have an attractive appearance. A corrugated surface, when compared to a smooth one, can provide significantly better grip on objects that come into contact with it. This property, in fact, determines the main purpose of sheets on which corrugation is specially applied.
Shape and dimensions of rhombic corrugation
Sheets with rhombus-shaped corrugations can be produced in various standard sizes, namely:
- thickness, measured without the height of the ribbed profile, is 2.5–12 mm;
- width – 600–2200 mm;
- the length of products, the pitch of standard standard sizes of which is 50 mm, is 1400–8000 mm.
The most popular size among consumers of this product is 1500x6000 mm.
Permissible deviations of dimensions and weight according to GOST (click to enlarge)
The corrugation on the surface of such sheets consists of intersecting lines. The dimensions of the diagonals of the rhombuses obtained by these intersections can be in the range of 25–30 and 60–70 mm. Meanwhile, these dimensions are not fixed; by agreement between the customer and the manufacturer, they can be changed, as well as the location of the pattern on the surface of the sheet.
The "Rhombus" sheet is successfully used in many areas. Elements of staircase structures, bridges and passages are made from corrugated metal sheets, they cover the floors in industrial facilities, and they are used to equip escalators in the metro and large shopping centers. In addition, products with corrugation in the form of diamonds are used to reinforce floors, wall partitions are erected from them, and containers are made that are used not only in industry, but also in agriculture.
The decorative characteristics of this material make it suitable for the design of various architectural structures, which is actively used by modern designers. In private construction and for design purposes, corrugated metal sheets of small thickness are used, and for industrial facilities thicker products are purchased.
Weight of corrugated sheet depending on the thickness of the base
Since Rhombus corrugated sheets are made of metal, they are distinguished by high strength, and if stainless steel is used as such metal (which is allowed by GOST requirements), then they also have exceptional corrosion resistance. The material of such sheets has not only the ability to withstand significant loads, but also ductility and good workability. These characteristics of metal sheets with rhombic (and any other) corrugation significantly expand the scope of their application.
In the domestic sphere, Rhombus corrugated sheets have also found wide application. For example, they are used to construct fences and various enclosures, to make gates and wickets, casings and containers for various purposes.
Meanwhile, it should be kept in mind: if corrugated sheets of ferrous metal are used for the manufacture of structures, they must be coated with protective compounds so that they do not lose their visual appeal and other characteristics after a short period of operation.
