Two major classification of weathering steel plate

Weathering steel: classification of weathering structural steel, weathering grade, production method and weathering use.

1, high weathering steel: hot rolled, high weathering steel grade: Q295GNH Q355GNH high weathering steel use, used in vehicles, containers, buildings, towers or other structural parts and other structures, compared with welding weathering steel, has better resistance to large weather corrosion steel performance. Cold rolled high weathering steel, Q265GNH, Q310GNH, cold rolled weathering steel.

2, welding weathering steel: welding weathering steel grade: Q235NH, Q295NH, Q355NH, Q415NH, Q460NH, Q550NH Hot rolled welding weathering steel uses: for vehicles, containers, buildings, towers or other structural parts and other structures, compared with high weathering steel, has better welding performance.
