1. The flange is wide and the lateral stiffness is large. Strong bending resistance.
2. The two surfaces of the flange are parallel to each other, making connection, processing and installation easy.
3. Compared with welded I-beam, it has low cost, high precision and small residual stress. It does not require expensive welding materials and weld detection, saving about 30% of the cost of steel structure production.
4. Under the same cross-sectional load. Hot-rolled H steel structure is 15%-20% lighter than traditional .
5. Compared with the concrete structure, the hot-rolled H steel structure can increase the use area by 6%, while the structure's self-weight is reduced by 20% to 30%, reducing the internal stress of the structural design.
6. H-shaped steel can be processed into T-shaped steel, and honeycomb beams can be combined to form various cross-sectional forms, which greatly meets the needs of engineering design and production.
