What is welding structure type weathering steel

The weathering steel for electric welding structure is mostly produced by hot rolling. Compared with high weather resistance structural steel, the weathering steel for electric welding structure has lower atmosphere corrosion resistance.

The common grades of weathering steel for welding structure are Q235NH, Q295NH, Q355NH, Q415NH, Q460NH, Q500NH, Q550NH, etc.

The welding structure type weathering steel is mainly used in vehicles, bridges, containers and buildings. Although the weathering steel used for welding structure is slightly poor in weathering resistance, its welding performance is very outstanding.
