About S355J2W Weathering Steel Plates
S355J2W Weathering Steel Plates are high-strength atmospheric corrosion-resistant structural steel plates manufactured according to EN 10025-5 standards. Commonly known as Corten steel plates, these materials are specially engineered to develop a protective oxide patina layer that significantly reduces atmospheric corrosion and extends service life in outdoor environments.
Unlike conventional carbon steel, S355J2W plates provide superior resistance against moisture, industrial pollution, rain, coastal environments, and changing weather conditions, reducing maintenance costs and eliminating the need for repeated painting in many structural applications.
These weathering steel plates offer an excellent combination of high tensile strength, impact toughness, weldability, durability, and architectural appeal, making them widely used in bridges, railway wagons, transmission towers, architectural facades, industrial chimneys, containers, outdoor sculptures, coastal infrastructure, and heavy structural engineering projects.

FAQs on S355J2W Weathering Steel Plates
S355J2W is a corrosion-resistant structural steel plate manufactured according to EN
10025-5 standards. It develops a protective oxide patina layer that improves atmospheric
corrosion resistance and increases outdoor service life.
Yes. S355J2W is commonly referred to as Corten or weathering steel because of its
atmospheric corrosion resistance and self-protecting rust-like surface layer.
