H beam steel is an economical cross-section and high-efficiency profile with more optimized cross-sectional area distribution and more reasonable strength-to-weight ratio. It is named because its cross-section is the same as the English letter "H". Since all parts of H-shaped steel are arranged at right angles, H-shaped steel has the advantages of strong bending resistance in all directions, simple construction, cost saving and light structural weight, and has been widely used.
H-shaped steel has an economical and reasonable cross-section shape and good mechanical properties. During rolling, the extension of each point on the cross-section is relatively uniform and the internal stress is small. Compared with ordinary I-beam steel, it has the advantages of large section modulus, light weight and metal saving, which can make buildings The structure is reduced by 30-40%; and because the inner and outer sides of the legs are parallel and the leg ends are at right angles, they can be assembled into components, which can save 25% of the welding and riveting workload.
It is often used in large buildings (such as factories, high-rise buildings, etc.) that require large interception capacity and good cross-sectional stability, as well as bridges, ships, lifting and transportation machinery, equipment foundations, brackets, foundation piles, etc.
