Corten steel is a particularly robust structural steel. The word "Corten" is the brand name for a weather-resistant steel alloy. When exposed to the elements, this steel forms an outer protective layer that protects it from corrosion.
The main advantages are:
Very high resistance to corrosion and weathering, up to 8 times greater than that of conventional steel, which makes it particularly suitable for natural oxidation outdoors when in contact with air. It then forms a protective layer that prevents any further rust.
In addition, this patina gives it a beautiful warm, brown color, the shade of which can vary over the years and depending on the exterior environment.
CorTen is often considered a “living” material that protects itself. Indeed, if its surface patina is damaged or scratched, it will oxidize again to create a new protection. This regeneration phenomenon can be repeated several times, thus guaranteeing constant protection.
