What Is Corten Steel Cladding?
Corten steel cladding is made from weathering steel. It forms a rust layer when exposed to air. This rust layer is called patina. It protects the metal from further damage from rain and sun. It is suitable for a maintenance-free exterior. The brown-orange steel color looks bold and natural. People use weathering steel panels on buildings, fences, and retaining walls. It handles atmospheric corrosion better than regular steel. Corten steel cladding offers strength, style, and durability without extra upkeep.
