Product Description

H-beam steel is a type of steel beam made of rolled steel, it is named because its section is the same as the letter "H". Since all parts of H-beam steel are arranged at right angles, H-beam steel has been widely used for its advantages of strong bending resistance, simple construction, cost saving, and light structural weight.The section shape of H-beam steel is reasonable, and its mechanical properties are great. Because the inner and outer sides of the legs are parallel and the leg ends are at right angles, the welding and riveting work can be saved by 25%. With large bearing capacity and good section stability, it is commonly used for large buildings, such as factories, as well as bridges, ships, lifting, and transportation machinery, equipment foundations, supports, foundation piles, etc.
