Diamond plate, also known as checker plate - a type of flat steel sheets with a convex pattern applied on it. It is made in the hot-rolled way. Requirements for this rental are regulated by GOST 8568-77. For its manufacture, carbon steel is used — St0 — St3, whose chemical composition must comply with the requirements of GOST 380-94. There are several types of corrugated sheet. The most common - the convexity (riffle) are located at a right angle to each other.
Advantages of riffled sheet
Riffled steel sheets are used in various production facilities (workshops, workshops, etc.) as the surface on which people walk. These can be stair steps and platforms, passages, etc. Due to the presence of the rifle, high adhesion properties are provided, minimizing the likelihood of slippage of the shoes, and thus ensuring a high level of personnel safety.
Range of steel riffled sheet
The riffled sheet is produced with a thickness of 2.5 - 12 mm, a length of 1400-8000 mm and a width of 600-2200 mm. The height of the rifle must be at least 0.5 mm. Gradation in length and width is 50 mm. Depending on the thickness of the sheet, riffled steel is supplied in rolls or sheets (grooved always on one side of the sheet). The thickness and weight of a square meter of a riffled sheet according to GOST 8568-77 are:

Like other types of rolled metal, reffled sheet can be made of measured length, multiple of measured length and non-measured length. In terms of precision, this product is high and normal accuracy. According to GOST 8568-77, a reffled sheet can have two types of pattern: with rhombic ribs and with lentil ribs. Rhombic ribs are straight lines intersecting at a certain angle with a pitch of 25-70 mm. When lentil corrugation riffles have the shape of lentils (oval), located at an angle of 90º to each other. The distance between them is 25-30 mm.
