SMA50CP steel is a structural weathering steel, also known as an atmospheric corrosion resistant steel. Its main alloying elements are chromium-nickel and copper with the addition of phosphorus, resulting in excellent self-protection. When the steel reacts with elements in the atmosphere, the material forms a layer of rust over time, essentially protecting the steel from corrosion.
