Corten B Weather Resistant Steel Plate 2-300mm Thickness ASTM A588 A242 Standards for Building Construction
Corten B is a high-strength weathering steel alloy that forms a protective rust-like patina when exposed to weather, eliminating the need for protective coatings or paints. This self-protecting characteristic makes it ideal for architectural and structural applications where maintenance-free durability is essential.
