H-beam is a new type of economic construction steel. The section shape of H-shaped steel is economical and reasonable, and the mechanical properties are good. The points on the section during rolling are more uniform and the internal stress is small. Compared with ordinary I-beams, it has the advantages of large section modulus, light weight and metal saving. The structure is reduced by 30-40%; and because the inside and outside of the leg are parallel, the leg ends are right angles, and assembled into components, which can save welding and riveting work up to 25%. It is often used in large buildings (such as workshops, high-rise buildings, etc.) that require large interception capacity and good cross-section stability, as well as bridges, ships, lifting and transport machinery, equipment foundations, supports, foundation piles, etc.

The main materials of H-beam are Q235B, SM490, SS400, Q345, Q345B and so on.

Application range:H-beam is mainly used for beam and column members in industrial and civil structures.
