Corten Steel letterbox
Corten Steel, also known as weather resistant steel, is a steel alloy made of iron which has copper, silicon, nickel and chromium added. As soon as Corten Steel is exposed to the elements it will naturally weather and develop a protective layer of rust, this can take several months. This natural fixed coating of rust provides protection against further corrosion. Characteristic of Corten Steel is the orange brown rust colour and its longevity.
