Corten Steel
What Is Corten Steel?
Corten steel, also known as weathering steel, is a group of steel alloys designed to form a stable rust-like appearance after exposure to weather. The name “Corten” is derived from a combination of “corrosion resistance” and “tensile strength.” This unique steel was developed to eliminate the need for painting and form a stable rust-like appearance if exposed to the weather for several years.
Corten is becoming increasingly popular for building facades, cladding, roofing, sculptures and landscaping features.
The Science Behind Corten Steel
The secret to Corten steel’s weathering ability lies in its composition. It contains a mixture of copper, chromium, and nickel, which gives it its weather-resistant properties. When exposed to the elements, Corten steel forms a protective layer of rust that adheres to the surface, preventing further corrosion and thereby extending the life of the structure.
