Corten Steel

Name: Corten Steel
Brand: FacadArt

Self-protecting corten steel with a characteristic patina.

Corten steels contain special alloys that show high resistance to atmospheric corrosion. These alloys generally contain elements such as copper, nickel, chromium and phosphorus. By controlling and slowing down the rusting process of the steel, these alloys increase its durability against atmospheric conditions.

The patina

The superior corrosion resistance of corten steel is achieved thanks to an oxide layer that forms naturally on the surface of the steel. This oxide layer coats the surface of the steel and prevents the core material from being exposed to corrosion. This layer is usually called the "patina" and creates the steel's natural brown-orange colour.

The patina layer forms over time depending on atmospheric conditions and determines the aesthetic appearance of corten steel. Corten steels have become a preferred option especially in architectural applications where durability and aesthetics are at the forefront.
