ASTM SA588 Grade A Corten steel pipe

SA588 Grade A Corten Pipe is a high-strength, low-alloy weathering steel pipe specified by ASME SA588. Designed to resist atmospheric corrosion, it develops a stable oxide layer (rust patina) that protects the steel from further degradation in outdoor or industrial environments—without the need for painting.

With a minimum yield strength of 50 ksi (345 MPa), SA588 Gr. A pipe is widely used in bridges, building frames, structural fencing, and exposed piping systems, especially where visual appeal and long-term performance are key.
