JIS G3101 SS490 H Beam
JIS G3101 SS490 H-shaped steel is a new type of economical building steel with good mechanical properties, uniform extension at each point on the rolled section, and low internal stress. Compared with ordinary steel, JIS G3101 SS490 H-shaped steel has the advantages of large section modulus, light weight, and metal saving, which can reduce the building structure by 30-40%; because its inner and outer legs are parallel and the leg ends are centered, the welding and riveting workload can be saved by 25% when assembled into components.
