Stainless steel section steel is an economical cross-section high-efficiency section with more optimized cross-sectional area distribution and more reasonable strength-to-weight ratio. Since all parts of the H-shaped steel are arranged at right angles, the H-shaped steel has the advantages of strong bending resistance in all directions, simple construction, cost saving and light structure weight, and has been widely used in engineering, plant equipment, and mechanical equipment. , bridges, highways, houses, etc.
