H-beam is a kind of new economic construction steel whose section shape is economical and reasonable, with good mechanical properties, uniform extending on every direction of the cross section and small internal stress when rolling. Compared with ordinary I beam, it has the advantages of big section modulus, light weight and metal saving which can make the weight of building structure reduced 30-40%; And also because of its paralleled internal and external sides of the webs, right-angled edges, assembled and combined into components which in total can saving the workload of welding and riveting to 25%.
