1. European standard H-beam is a new type of economic construction steel. The section shape of European standard H-beam is economical and reasonable, and its mechanical properties are good. When rolling, all points on the section extend evenly and the internal stress is small. Compared with ordinary I-beam, it has the advantages of large section modulus, light weight and metal saving, which can reduce the building structure by 3-4%. Because the legs are parallel inside and outside, and the leg ends are right angles, the welding and riveting workload can be saved by 25%.

2. European standard H-beam can be processed into T-beam, and honeycomb beam can be combined to form various cross-section forms, which greatly meets the requirements of engineering design and production. Under the same section load, the weight of hot-rolled H steel structure is 15%-2% less than that of traditional steel structure. Compared with welded I-beams, it has the advantages of low cost, high precision, small residual stress, no need for expensive welding materials and weld detection, and 3% saving in steel structure manufacturing cost.
