corten steel sheet (ASTM standard called Corten Steel) is a special steel that forms a dense oxide layer on the surface to achieve self-protection function by adding copper, chromium, nickel and other alloying elements (content 2-3%). Its core advantages include:

Stable corrosion protection in exposed environments (50-100μm)

Atmospheric corrosion resistance is 2-8 times that of ordinary carbon steel

The whole life cycle maintenance cost is reduced by more than 40%

Environment-friendly and paint-free features meet LEED certification requirements
