09CuPCrNi-A Corten Steel Pipe

09CuPCrNi-A is a Chinese standard weathering steel grade, equivalent in function to international corten steels such as ASTM A588 and EN S355J0WP. It is specially formulated with copper, chromium, nickel, and phosphorus, which promote the formation of a stable rust-like layer under atmospheric conditions.

This corten-equivalent steel offers high tensile strength, corrosion resistance, and visual appeal, making it highly favored in urban architecture, landscape design, container production, and outdoor steel structures across Asia and abroad.
