Steel hot-rolled I-beams 
I-beam is a metal product used in concrete panel, industrial and civil construction for blocking, column metal structures, bridge erections, supporting elements and overhead rails.
I-beams differ by the thickness of the wall and flange, by location of flange edges (with parallel edges, with inclined internal edges), by purpose, by method of production and by specifications.
This standard stipulates the assortment of hot-rolled steel I-beams with inclined internal flange edges. 
 
1. Cross-section of I-beams must correspond to that stated in the drawing 
h – I-beam height;
b – flange width;
s – wall thickness;
t – wall average thickness;
R – internal rounding radius;
r – flange rounding radius;
 
Note. The inclination of internal flange edges must be 6-12 %.


2. Nominal dimensions of I-beams, cross section area, weight and reference values for axes shall meet the values in the table
