H-beam is a new type of economic construction steel. H section steel is economical and reasonable in cross-sectional shape and has good mechanical properties. The points on the cross section of the H-beam are extended uniformly and the internal stress is small. Compared with ordinary I-beam, H beam has the advantages of large section modulus, light weight and metal saving, Structure to reduce 30-40%; and because of its parallel to the inside and outside the legs, leg ends are right angles, assembled into components, saving welding, riveting workload up to 25%. Commonly used in large-scale buildings (such as factories, high-rise buildings, etc.) that require large bearing capacity and good cross-sectional stability, as well as bridges, ships, hoisting and transporting machinery, equipment foundations, brackets and foundation piles.

H-beam is made of I-shaped steel optimized development of a cross-section more excellent mechanical properties of the economic section of steel, especially the cross-section with the English letter "H" the same name. Its characteristics are as follows:

◆ wide flange, lateral stiffness.

◆ Bending ability, about 5% -10% than I-beam.

◆ flanges parallel to each other so that the two surfaces, processing, installation is simple.

Compared with welded I-beam, low cost, high precision, small residual stress, without expensive welding materials and weld testing, saving about 30% of the cost of steel production.
