TB/T 1979 Corten Steel Coil

TB/T 1979 Corten Steel Coil is a high-performance weather-resistant steel designed for use in environments where corrosion resistance is critical. Commonly used in outdoor applications such as architectural facades, bridges, and structural frameworks, this steel alloy offers excellent resistance to atmospheric corrosion. By developing a stable, protective patina layer over time, it significantly reduces maintenance costs and extends the lifespan of structures.
