Q345GNH Weather Resistant Steel Plate

Corten steel is a weathering steel, a material that is resistant to corrosion and develops an outer patina in the absence of a coating. It is a high-strength alloy steel that is used in materials that require higher strength and longer life cycles, especially where unrestricted alloys are required.

Q345GNH Weather Resistant Steel Plate China Manufacturer

Q345GNH Steel Plate Bridge Features: Traditional high-strength bridge steel not only has poor impact toughness, weldability and fatigue properties, but also cannot resist the corrosion of the atmosphere and marine environment. Therefore, the concept of High Performance Steel (HP) III has been proposed abroad. Q345GNH steel plate has a high strength, but its welding properties, low temperature toughness, especially corrosion resistance has also been greatly improved. Weathering steel is a low alloy steel between ordinary steel and stainless steel, weathering resistance is 2 to 8 times than ordinary steel. High performance weathering bridge steel can resist corrosion from industrial atmosphere, acid rain, marine atmosphere and seawater, and is suitable for uncoated use in inland and coastal bridges.
