Q420 HN CARBON STEEL H BEAM as a new type of economic construction steel. The section shape of H-beam steel is economical and reasonable, the mechanical properties are good, and the elongation of each point on the section is uniform and the internal stress is small. Compared with the ordinary I-beam steel, it has the advantages of more large section modulus,more light weight and more saving metal, which can reduce the building structure by 30-40%.

And because its legs inside and outside parallel, leg end is a right Angle, assembled into components, can save the workload of welding and riveting up to 25%. It is often be used in large buildings (such as workshops, high-rise buildings, etc.), as well as Bridges, ships, lifting and transportation machinery, equipment foundation, supports, foundation piles, etc.
