I-beam steel is a new type of steel for economic construction.  The section shape of I-beam is economical and reasonable, and I Beam Steel 's mechanical properties are good.The extension of each point on the section is more uniform and the internal stress is small during rolling.  Compared with ordinary H-beam,  I Beam Steel has the advantages of large section modulus, light weight, and metal saving, which can make building The structure is reduced by 30-40%;  because the legs are parallel inside and outside, and the ends of the legs are at right angles, I Beam Steel can be assembled into components, which can save up to 25% of the welding and riveting workload.
