EN 10155 specifies structural steels with improved atmospheric corrosion resistance, commonly known as weathering steels. These steels are alloyed to develop a protective oxide layer when exposed to suitable atmospheric conditions, helping to reduce corrosion and maintenance requirements. EN 10155 covers structural steel sheet, plate, and strip in grades such as S235J0W, S235J2W, S355J0WP, S355J2WP, S355J0W, S355J2G1W, S355J2G2W, S355K2G1W, and S355K2G2W. Manufactured in accordance with EN 10155, these weather-resistant structural steels provide a combination of structural strength, atmospheric corrosion resistance, toughness, and durability. They are available in different product forms and grades according to the required mechanical and service conditions. Ladhani Metal Corporation supplies EN 10155 structural steel sheet, plate, and strip in various sizes, thicknesses, widths, and lengths to meet industrial and structural requirements.

This patina can slow further corrosion and provide long-term weather resistance. The material combines structural strength with improved resistance to atmospheric corrosion, making it suitable for exposed steel structures. Applications: • Bridges and Bridge Components • Structural Buildings • Railway Structures • Outdoor Steel Structures • Industrial Structures • Transmission Towers • Heavy Engineering • Storage and Transportation Structures • Architectural Structures • Infrastructure Projects Conclusion: EN 10155 Structural Steels Sheet, Plate & Strip provide a practical combination of structural strength and improved atmospheric corrosion resistance.
