Assortment corresponds to GOST 8509-93. Precision classes:
A - high precision;
B - ordinary precision.
The number of equal flange steel corresponds to flange width, expressed in mm. For example: Angle 25 -flange width 25mm. All other sizes (wall thickness and etc.) according to GOST (shown in the table of GOST book of reference).
Hot-rolled flat bar - the most sought-after type of strip. Distinguish rolled dimensional (length 0.6 and 1.2 m), a multiple of the measured length and unmeasured (length 0.2 - 0.6 m). At the same time, a bar with a thickness of up to 4.5 mm is produced with a width of all sizes provided for by GOST. In accordance with GOST 103-76, the size of this product may vary in the range:length - 2-10m; width - 20 200 mm;thickness - 4 - 40 mm.
The material of manufacture and the range of the round bar in accordance with GOST 2590-2006, where the bar can be made of steel of the following grades: carbon (St3, St20, St35, St45); low alloyed (Steel 40X, Steel 40XH); high-alloyed (08 18 10, 38XH3MA, 40 2 14 17 2 and others), high-speed (U7; U7A; U8A)
