Corten Steel Exterior Cladding

Corten steel and carbon steel differ significantly in both composition and performance. Corten steel contains alloying elements such as copper, chromium, and nickel, which allow it to form a protective rust layer, making it highly suitable for exterior cladding applications. In contrast, carbon steel lacks these alloying elements and requires protective coatings to prevent continuous corrosion. Therefore, corten steel is preferred for modern architectural façade systems where durability, appearance, and low maintenance are essential.
