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:
The assortment of I-beams with parallel flanges can correspond to either GOST 26020-83, or its own unique technical specification STO ASCHM 20-93 of Nizhniy Tagil metallurgical plant, that is the main supplier of I-Beams in Russia.
I-Beams with sloping edges of flanges:
normal (edge slope 6-12%) GOST 8239-89: №10, 12, 16 and etc.;
Assortment of such I-Beams corresponds to GOST 8239-89.
Special (M and S):
Assortment of such double flanged beams corresponds to GOST 19425-74.
The number of the I-beam is its conventional size (height) in cm.
Example: normal I-beam 30B1 - h (height of the beam)=296mm
normal I-beam 30B2-h=299mm. The rest of the dimensions: width of the flanges, thickness of the walls and etc. is made according to GOST.
The minimum size of the I-beam is 10, maximum - 100 (100B4). All, that is above or below this specification can only be made by special order to factory-producer.
The size of the I-beam - is the length between the outer flange edges.
Double flanged beams are used in large-panel, industrial and civilian construction of floors, column metal constructs, bridges, supports and hanging rails.
