Hot-rolled steel channels This type of channel is produced according to GOST 535-88 with parallel flanges and sloping flanges: 10, 10P and etc. The slope of inner flanges must not exceed 10%. Assortment of the steel hot-rolled channel corresponds to GOST 8240-89. The number of the channel corresponds to its size (distance between the inner flanges) expressed in cm. For example: Channel #10 - distance between the inner flanges equals 10cm. All other parameters: flange width, wall thickness and etc. according to GOST. Channel that has letter A at the end of the number (14A) is a channel with sloping inner flanges, it means the flanges are wider and hence the weight of each meter is larger than ordinary channel. There are special types of hot-rolled channel: special channel for automotive industry - GOST 19425-74 (18S, 20S); special channel for wagon production - GOST 5267.1-90 (8W, 14W, 18W).
I-BEAM- double flanged - this type of products include hot rolled double flanged beams (I-beams), produced according to GOST 535-88. I-Beams are separated into several types: I-Beams with parallel flanges normal (20B, and etc.) wide flanges (20Sh and etc.) column (20K and etc.) I-Beams with sloping edges of flanges normal (edge slope 6-12%) GOST 8239-89 (â??10, 12, 16 and etc.) Assortment of such I-Beams corresponds to GOST 8239-89. Special (M and C): M - for hanging rails (edge slope not more than 12%): 18M, 24M, 30M and etc.; C - for reinforcement of mine shafts (edge slope not more than 16%): 14S, 20S and etc. Assortment of such double flanged beams corresponds to GOST 19425-74. The number of the I-beam is its conventional size (height) in cm.
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)
Steel square can be made of steel of various grades: carbon - St3, St20, St35; St45 low alloyed - Steel 40X, Steel 40XH; high-alloyed - 08 18 10; 40XH2MA; 38XH3MA; 14 17�?2 and others high-speed - U7; U7A; U8A
Thermally strengthened periodically profiled steel rods of the diameter 6-40mm - the so called thermic is used for the construction of strategic reinforced concrete structures, GOST 10884-81. According to the standard this rebar is made out of these types of steel: AtIII - St (sp, ps); AtIV, AtIVK - 20GS, 25G2S, 35GS, 28S, 10GS2, 08G2S, 25S2P; AtV(K and SK) - 20GS, 20GS2, 08G2S, 10GS2, 28S, 25G2S, 35GS, 25S2R, 20HGS2; AtVII - 30HS2.
