Q355GNH corten steel sheet metal
Weather Resistant Steel Products Description
The implementation standard of Q355GNH corten steel sheet metal is GB/T 4171-2008 Weathering Structural Steel. It is mainly used to manufacture structural parts such as vehicles, bridges, containers, and buildings, and can be used for a long time in atmospheric environments.
Q355GNH corten steel is a type of weathering steel sheet with good atmospheric corrosion resistance. "Q" represents yield strength, "355" represents yield strength value, and "GNH" represents "high weathering resistance".
Q355GNH corten sheet usually contains appropriate amounts of copper, chromium, nickel and other elements, which can form a dense oxide film on the surface of the steel sheet, thereby improving its corrosion resistance.
