Because all parts of steel H beam are arranged at right angles, steel H beam has the advantages of strong bending resistance, simple construction, cost saving and light structure weight in all directions, and has been widely used.

Steel H beam has wide flange, thin web, many specifications and flexible use, which can save metal by 15% ~ 20% when used in various truss structures. Because the inner and outer sides of the flanges are parallel, and the flange ends are at right angles, it is convenient to assemble and combine into various components, thus saving about 25% of the welding and riveting workload, greatly accelerating the construction speed of the project and shortening the construction period.
