I Steel also named steel beam is the cross section for the i-section of strip steel.I Steel are widely used in various building structures, bridges, vehicles, stents, machinery, etc.
1、I Steel basic on Waist height ( h)*Leg width (b)*Waist depth(d)，such as“I 160*88*6”，Waist height 160mm，Leg width 88mm，Waist depth 6mm .
2、I Steel's model also can use # on show，such as I 16#.High waist the same beams.such as several different width and waist thick legs.Need to add on the right side model a b c .such as 32a# 32b# 32c#etc.I-steel regular i-steel and light beams, hot rolled beams of average of 10-63 #.
Representation：Waist height ( h)*Leg width (b)*Waist depth(d)
Weight calculation formula： W= 0.00785×（hd+2t b） h= High b= Leg lengh d= Waist thickness t= average legs thickness
