weld H beam

weld H beam Steel H beam is a kind of new economical structural steel. Compared with ordinary I beam ,the internal stress of H beam is small ,section modulus is big ,weight is light ,which causes structure weight reduce 30% 40%.Welded H beam is much lighter and thus save cost than hot-roll beam ,but with the same performamance. Due to its good mechanical performance,it is used in many constructions ,especially those large-scaled constructions,workshop,bridges and so on.
