GB/T 4171 Corten Steel Coil

 GB/T 4171 Corten Steel Coil is designed to meet the rigorous demands of atmospheric corrosion resistance. This steel forms a stable, rust-like patina that protects the underlying material from further weathering. Often used in construction, civil engineering, and architectural applications, the GB/T 4171 Corten steel is perfect for long-term exposure to outdoor elements.

🔹 Available Grades
