Product Details
When looking for Corten steel panels for sale, it is important to understand the common grades (grades/brands) and international standards used for weathering steel. These standards ensure consistent corrosion resistance, mechanical strength, and suitability for architectural and structural applications.
Common Corten Steel Grades
Corten steel is mainly divided into two widely used ASTM grades:
1. ASTM A588 (Corten A Equivalent in Some Markets)
ASTM A588 is a high-strength low-alloy structural steel.
Key features:
- High atmospheric corrosion resistance
- Strong structural performance
- Suitable for outdoor load-bearing structures
Common applications:
- Building façades
- Bridges and structural frameworks
- Outdoor architectural panels
2. ASTM A606 (Sheet & Coil Weathering Steel)
ASTM A606 is commonly used for thinner sheet and coil products.
Key features:
- Excellent formability
- Ideal for decorative panels
- Suitable for laser cutting and fabrication
Common applications:
- Corten wall panels
- Decorative screens
- Landscape installations
Equivalent International Standards
Corten steel is also known under different names depending on the region:
| Standard System | Grade Name | Equivalent Use |
|---|---|---|
| ASTM (USA) | A588 / A606 | Most common export standard |
| EN (Europe) | S355J0WP / S355J2W | European weathering steel |
| JIS (Japan) | SPA-H | Japanese weathering steel |
| China Standard | Q355NH / Q235NH | Domestic weathering steel grades |
👉 Although names differ, all belong to weathering steel family materials.
Difference Between Corten A and Corten B (General Reference)
In commercial markets, Corten is often simplified into two types:
Corten A (Equivalent: ASTM A606 / EN S355J0WP)
- Better for thin sheets and decorative panels
- Good formability
- Common in architectural design
Corten B (Equivalent: ASTM A588 / EN S355J2W)
- Higher strength
- Better for structural applications
- Used in bridges and heavy façades
Key Standards for Corten Steel Panels
When purchasing Corten steel panels, common specifications include:
Mechanical Standards
- High tensile strength
- Yield strength typically 345 MPa or higher
- Designed for structural stability in outdoor environments
Weathering Performance Standard
- Must pass atmospheric corrosion resistance testing
- Forms stable protective rust patina
- Reduced corrosion rate compared with carbon steel
Typical Product Forms for Sale
Corten steel panels are commonly supplied in:
- Flat sheets (laser cut panels)
- Wall cladding panels
- Perforated decorative panels
- Folded façade cassette panels
- Custom architectural shapes
Why Standards Matter When Buying Corten Steel Panels
Choosing the correct standard ensures:
- Stable weathering performance
- Consistent rust color development
- Structural safety for façade systems
- Compatibility with architectural design requirements
Common Applications
- Building exterior wall systems
- Architectural façade cladding
- Landscape and garden design panels
