What is Corten Steel Grade S355J2W Plate?
Corten Steel Grade S355J2W Plate is a high-strength low alloy structural steel that belongs to the family of weathering steels. It is designed to provide improved corrosion resistance in outdoor and atmospheric conditions, making it ideal for applications exposed to the elements. The steel develops a stable rust-like appearance after exposure to weather, which acts as a protective layer to resist further corrosion. This self-protective nature eliminates the need for painting or coating, which significantly reduces maintenance costs and environmental impact.
S355J2W Plate is specified under EN 10025-5 standards, widely accepted across Europe and now adopted globally due to its performance. The “S355” stands for the steel’s minimum yield strength of 355 MPa. The “J2” signifies that the material has undergone a Charpy impact test at -20°C, ensuring its toughness even in cold environments. The “W” indicates its weather-resistant properties. This steel grade offers excellent mechanical performance, durability, and workability, making it suitable for both architectural and industrial projects.
For clients looking for both strength and weather resistance in one material, S355J2W is the preferred choice. It performs well in rough environments and offers a naturally appealing finish that blends well with modern designs and natural landscapes.

Applications of Corten Steel S355J2W Plate
Corten Steel S355J2W plates are widely used in industries that demand durability, strength, and corrosion resistance—especially in outdoor environments. One of the most significant uses of this steel is in architectural facades, where designers look for a visually appealing rusty texture without compromising the structural integrity. Its natural patina gives buildings a modern, rugged, and industrial aesthetic that eliminates the need for paints or coatings.
In bridge construction, S355J2W is commonly used for both pedestrian and vehicular bridges. Its strength and resistance to atmospheric conditions make it an ideal material for structures that are continuously exposed to rain, wind, and pollutants. This helps increase the life span of the bridge while minimising maintenance efforts.
Equivalent Grade of Corten Sreel Sheet Supplier
Corten Steel Sheet Supplier is a weather-resistant steel that is designed to develop a protective rust-like surface layer when exposed to the elements. It is also known as Cor-Ten A. The equivalent grades of Corten A steel plates can vary depending on the specific international standards or regional specifications. In general, the most closely related international standards to Corten A are:
EQUIVALENT GRADE OF CORTEN STEEL SHEET
