Product Overview
The Q295GNH Corten Steel Plate is a low carbon alloy weathering steel with excellent welding and forming properties. It is designed for superior atmospheric corrosion resistance, making it ideal for long-term exposure in outdoor environments.
By adding alloying elements such as Cr, Ni, Cu, and controlling impurities like S and P, the steel maintains high strength while developing a protective oxide layer that resists rust penetration.
This Hot Rolled Q295GNH Corten Steel Plate is widely used in railway structures, bridge construction, high-speed train bogies, container manufacturing, outdoor cladding, marine structures, and other applications requiring exceptional weather resistance.
