JIS G3101 SS490 I-beam can be manufactured as ordinary steel or light, since the cross-sectional dimensions are relatively high, narrow, the cross-sectional moment of inertia of the spindle have larger difference between two. JIS G3101 SS490 I-beam can on

JIS G3101 SS400 I-beam are also known as I-beam steel beam, and the cross-section strip of steel word shape. JIS G3101 SS400 I-beam are widely used in various building structures, bridges, vehicles, support, machinery and so on . JIS G3101 SS400 ordinary

JIS G4051 S20C I-beam belongs to low-carbon steel, S20C I-beam’s strength is slightly higher than S15C, and it has good toughness, ductility and weld ability . S20C I-beam is correspond to the German DIN standard steel CK22 / C22 and American AISI / SAE s

SM490 YA/YB I-beam production is based on the Japanese hot rolled low alloy steel standard G3106 JIS. SM490 YA/YB I-beam is a low carbon, high strength steel. It is easy for welding and has good cold forming properties.

SM490 A/B/C I-beam is used in welded structure such as bridges, ships, rolling stocks, petroleum storage tanks, containers and other constructions that require superiority in weld ability.

SM400 A/B/C I-beam production is based on the Japanese hot rolled low alloy steel standard G3106 JIS. SM400 A/B/C I-beam is suitable for bridges, ships, vehicles, oil tanks, containers and other structural parts with good welding performance.
