Q355 Q235 Channel Beams

Q235 steel is a carbon structural steel. It is equivalent to A3 and C3 steel in the old standard GB700-79 grade, which is the grade of Russian TOCT. The Q in the steel number stands for yield strength. Under normal circumstances, the steel is used directly without heat treatment. Q355B material is a low-alloy high-strength structural steel, where "Q" means yield strength, 355 means that the yield strength of this steel is 355MPa, and its yield value will decrease as the thickness of the material increases.
