H-shaped steel is a new type of economical steel for construction. The cross-sectional shape of H-shaped steel is economical and reasonable, with good mechanical properties. When rolled, the extension of each point on the cross section is relatively uniform and the internal stress is small. Compared with ordinary I-shaped steel, it has the advantages of large cross-sectional modulus, light weight, and metal saving, which can reduce the building structure by 30-40%; because its inner and outer legs are parallel, and the leg ends are right angles, it can be assembled into components, which can save 25% of welding and riveting work. It is often used in large buildings (such as factories, high-rise buildings, etc.) that require large cross-sectional capacity and good cross-sectional stability, as well as bridges, ships, lifting and transportation machinery, equipment foundations, brackets, foundation piles, etc.

H-shaped steel is an economical cross-sectional steel with better cross-sectional mechanical properties developed from the optimization of I-shaped steel, especially the cross-sectional shape is the same as the English letter "H". Its characteristics are as follows:

Wide flange and large lateral stiffness. Strong bending resistance, about 5%-10% higher than I-shaped steel.

The two surfaces of the flange are parallel to each other, making connection, processing and installation simple.

Compared with welded I-beams, it has low cost, high precision, low residual stress, no need for expensive welding materials and weld inspection, and saves about 30% of the cost of steel structure production.

Under the same cross-sectional load, the weight of hot-rolled H-steel structure is 15%-20% lighter than that of traditional steel structure.

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.
