S355K2W Corten Steel Pipe

S355K2W is a high-strength low-alloy weathering steel defined under EN 10025-5, offering enhanced corrosion resistance and impact toughness. Its defining feature is its guaranteed Charpy V-notch impact energy of 40J at -20°C, making it ideal for cold-weather or safety-critical structural applications.

With alloying elements such as copper, nickel, and chromium, S355K2W naturally forms a dense patina that protects the surface from further corrosion. It offers both aesthetic value and structural durability, making it a premium corten steel option for bridges, offshore structures, and public infrastructure in harsh climates.
