Corten steel is a weathering steel alloy that is designed to form stable rust-like appearance on the surface. Like copper, Corten's defensive layer protects the metal that’s beneath from corrosion. When exposed to natural weather over the years, a marbling of different shades of rich orange and brown forms on the surface of the metal, similar to that of rust. Due to its natural appearance, it eliminates the need for painting and upkeep, making it a very low maintenance choice. On top of its unique aesthetic, Corten sheets are easily formed into panels and can be manipulated into custom architectural shapes and designs.
