Galvanized I beam

H-beam is a new type of economic construction steel. The section shape of H-shaped steel is economical and reasonable, and the mechanical properties are good. The points on the section during rolling are more uniform and the internal stress is small.Compared with ordinary I-beam, it has the advantages of large section modulus, light weight and metal saving. The structure is reduced by 30-40%; and because the inside and outside of the leg are parallel, the leg ends are right angles, and assembled into components, which can save welding and riveting work up to 25%.
