H-beam section is a type of economic construction steel,

               it's shape is of economic and reasonable design.

   Good mechanics performance.

· Rolling section on each extension point is relatively uniform.

· Light weight, saving metal by about the 30-40% of the whole structure

· Combined into components, can save welding, riveting work of 25%.

· Small internal stress.

   H Beam size always shows as WEB HIGHT*FLANGE WIDTH*WEB THICKNESS*FLANGE THICKNESS*(198*99*4.5*7MM)

   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...
