The IVAR corten steel letterbox has a bold and warm look, thanks to the orange-brown patina on the metal. This patina is formed by a natural layer of rust. Another name for corten steel is weathering steel: weather conditions have a positive effect on this material.
Corten steel is a metal alloy made by adding copper, phosphorus, silicon, nickel and chromium to iron. When exposed to air, the material forms a protective layer of rust. This natural coating prevents further corrosion and makes the letterbox long-lasting.
