Q235 Black H Beam Steel H Beams 148*100*6*9mm use for Construction material

H Beam has advantage in average cross section area, and can afford high pressure and strength .

 

Steel H Beams

 

Description

 

   As a new type construction steel, H beam has useful sectional area, good mechanical strength, and has average elongation value while hot rolled. Compare to traditional I Beam, H type's accorss sectional area is bigger but weight is ligther and can save accessories material, all this can cut down the weigth of the structurcal bracket up to 30%~40%. Even more,becaus of the angle of every edge is vertical angle, so when it use for welded assembly it can save workload up to 25%.

   H Beam size always shows as WEB HIGHT*FLANGE WIDTH*WEB THICKNESS*FLANGE THICKNESS*(148*100*6*9MM),Length normally is 12meters.

   Since it's good mechanical property, it be widly used for big building(such as factory,high building etc...as well as bridge,vessel, lifting transportation machinery,basic structure bracket,basic pile and so on...
