CORTEN B – High-Strength Weathering Structural Steel Plate Corten B is a structural-grade weather-resistant steel, formulated for improved strength and toughness in load-bearing applications. Like Corten A, it forms a protective patina, but it’s better suited for industrial and heavy-duty structural uses due to higher mechanical strength. With alloying elements like copper and chromium, it offers long-term performance in outdoor and demanding environments. Key Highlights: High yield and tensile strength for structural integrity Excellent resistance to atmospheric corrosion No painting required—low lifetime maintenance Suitable for welding, forming, and standard fabrication Typical Applications: Bridges, overpasses, and civil infrastructure Shipping containers and offshore structures Structural frames in industrial buildings Storage tanks, chimneys, and large enclosures
