The characteristics of H-shaped steel mainly include high strength, good stability and excellent bending resistance. Its cross-section is “H” shaped, which can effectively disperse the force and is suitable for structures that bear larger loads. The manufacturing process of H-shaped steel makes it have better weldability and processability, and facilitates on-site construction. In addition, H-shaped steel is light in weight and high in strength, which can reduce the weight of the building and improve the economy and safety of the structure. It is widely used in fields such as construction, bridges and machinery manufacturing, and has become an indispensable material in modern engineering.
