ASTM A588 Grade A Corten steel pipe

ASTM A588 Grade A Corten steel pipe is a high-strength, low-alloy structural tubing with enhanced atmospheric corrosion resistance, making it ideal for outdoor and exposed environments. As part of the A588 weathering steel family, it develops a natural rust-like patina that protects the pipe from further corrosion—eliminating the need for painting or coating in many applications.

This pipe is widely used in bridges, architectural structures, outdoor installations, and industrial systems where strength and durability are critical.

✅ Key Features

• Superior Corrosion Resistance – Forms a stable oxide layer in outdoor settings

• Structural Grade Strength – Minimum yield strength of 50 ksi (345 MPa)

• Weldable & Formable – Ideal for fabrication, bending, welding

• Natural Aesthetic – Rust-colored patina blends with outdoor environments

• Low Maintenance – Cost-effective over long-term use

📌 Common Applications

• Outdoor handrails and balustrades

• Weathering steel fencing and gates

• Industrial chimneys and exhaust systems

• Exposed structural steel tubing for architecture

• Corten steel sculptures and landscaping

⚙️ Technical Specifications

Material Equivalent: Comparable to Corten A in weathering behavior, but stronger than mild steel pipes.
