The main advantages are:
High resistance to corrosion and weathering, up to 8 times higher than conventional steel, making it particularly suitable for the natural oxidation that occurs outdoors in contact with air, forming a protective layer that prevents further rusting. In addition, this patina gives it a warm brown color whose tone varies over the years and depending on the external environment.
Corten is considered a material that is "alive" and automatically protects itself. When the surface patina is actually damaged or scratched, it oxidizes again to build up new protection. This regeneration phenomenon can occur several times, maintaining a constant protection.
