H-beam steel is a new type of economic construction steel. The section shape of H-beam is economical and reasonable, and the mechanical properties are good. When rolling, every point on the section extends more evenly and the internal stress is small. Compared with ordinary "工"beam, H-beam has the advantages of large section modulus, light weight and metal saving, which can reduce the building structure by 30-40%. And because its legs are parallel inside and outside, the leg end is right Angle, assembly and combination into components, can save welding, riveting workload up to 25%. It is often used in large buildings requiring large bearing capacity and good cross-section stability (such as factories, high-rise buildings, etc.), as well as Bridges, ships, lifting and transportation machinery, equipment foundations, supports, foundation piles, etc.
H-section steel is a kind of economic section steel with better mechanical properties, which is optimized and developed from I-section steel, especially the section is named after the same as the English letter "H". Its characteristics are as follows:
◆ Wide flange, large lateral stiffness.
◆ Strong bending resistance, about 5%-10% than I-steel.
◆ The two surfaces of the flange are parallel to each other, making the connection, processing and installation easy.
◆ Compared with welded I-steel, low cost, high precision, low residual stress, no need for expensive welding materials and weld detection, saving steel structure production cost of about 30%.
◆ Under the same section load. The weight of hot-rolled H steel structure is 15%-20% less than that of traditional steel structure.
◆ Compared with the concrete structure, the hot-rolled H steel structure can increase the use area by 6%, and the structure's self-weight can be reduced by 20% to 30%, reducing the design internal force of the structure.
◆ H-shaped steel can be processed into T-shaped steel, and honeycomb beams can be combined to form various cross-section forms, greatly meeting the needs of engineering design and production.
