Corten Standard Steel Coil

Corten Standard Steel Coil, short for “CORrosion resistance + TENsile strength,” is a high-strength, low-alloy structural steel known for its superior resistance to atmospheric corrosion. Developed to eliminate the need for painting, it forms a stable, protective rust-like patina when exposed to weather, extending the service life of structures with minimal maintenance.

There are two primary grades: Corten A and Corten B, each designed for specific applications but both sharing similar corrosion resistance characteristics.

🔹 Corten A vs Corten B

🔹 Key Features

• Exceptional resistance to atmospheric corrosion

• Forms a protective oxide layer (patina) with time

• Low maintenance: no painting or coating needed

• High tensile and yield strength

• Excellent weldability and cold-forming performance

• Natural, rustic aesthetic appearance over time

🔹 Typical Mechanical Properties

🔹 Available Forms

• Plates and Sheets

• Coils and Strips

• Flat Bars

• Hollow Sections

• I-Beams / H-Beams

• Channels and Angles

• Custom profiles

🔹 Applications

• Architectural facades and cladding

• Landscape and garden design (planters, edging, screens)

• Bridges, railcars, and containers

• Outdoor furniture and public infrastructure

• Structural components in exposed environments

• Signage, sculptures, and artistic installations

🔹 Surface Finish

• As-rolled finish (naturally weathers over time)

• Pre-weathered (accelerated patina for immediate effect)

• Sandblasted or oil-coated available on request
