Corten Metal Wall Panels
Corten metal wall panels are widely used in modern architecture and landscape projects because of their unique rusted appearance and strong weather resistance.
Common specifications include thicknesses from 1.5 mm to 6 mm+ and standard panel sizes such as 1220×2440 mm and 1500×3000 mm. Customized laser cutting, perforation, bending, and large-format fabrication are also widely available for architectural wall systems and decorative facade applications.
- Description
Corten metal wall panels are wall cladding panels made from weathering steel (Corten steel). These panels develop a stable rust-like protective surface after exposure to outdoor environments, creating a natural industrial appearance while improving atmospheric corrosion resistance.
They are widely used in:
- Building facades
- Exterior wall cladding
- Garden walls
- Landscape architecture
- Commercial decoration
- Interior industrial-style design
Why Corten Steel Is Used for Wall Panels
Corten steel is highly suitable for wall systems because it combines:
- Decorative rust appearance
- Long outdoor service life
- Low maintenance requirements
- Good structural strength
- Natural weather-resistant performance
The surface oxidation layer protects the internal steel from further corrosion.
Common Grades of Corten Wall Panels
Common weathering steel grades include:
| Grade | Standard | Features |
|---|---|---|
| Corten A | Atmospheric corrosion resistant | Decorative architectural use |
| Corten B | Structural weathering steel | Heavy-duty outdoor structures |
| ASTM A588 | High-strength weathering steel | Structural construction |
| ASTM A606 | Weathering sheet steel | Wall panels and cladding |
Common Thickness of Corten Wall Panels
The thickness depends on installation method and structural requirements.
| Thickness | Common Applications |
|---|---|
| 1.5 mm | Interior decorative panels |
| 2.0 mm | Lightweight wall cladding |
| 3.0 mm | Standard exterior wall panels |
| 4 – 6 mm | Heavy-duty architectural walls |
| 6 mm+ | Structural facade systems |
Most Common Thickness
For decorative building facades:
- 2 mm
- 3 mm
- 4 mm
are the most commonly used specifications.
Common Panel Sizes of Corten Wall Panels
Corten wall panels are available in standard steel plate sizes or customized fabrication dimensions.
Standard Sheet Sizes
| Size (mm) | Size (ft) |
|---|---|
| 1220 × 2440 mm | 4 × 8 ft |
| 1500 × 3000 mm | 5 × 10 ft |
| 2000 × 4000 mm | Large facade panel |
| 1500 × 6000 mm | Long architectural panel |
Large Custom Panels
For architectural projects, larger customized sizes are often used to reduce visible joints and improve visual continuity.
Customized Wall Panel Processing
Corten wall panels can be customized according to project drawings.
Custom Processing Options
- CNC laser cutting
- Folded edge processing
- Perforated decorative patterns
- Curved panel fabrication
- Welded frame structures
This allows wall panels to match modern architectural designs.
Common Surface Conditions
1. Natural Steel Surface
Supplied without pre-rusting. The panel naturally develops a rust layer after outdoor exposure.
2. Pre-Rusted Surface
Panels are artificially weathered before shipment to create:
- Uniform rust color
- Faster decorative effect
- Stable appearance during installation
3. Sealed Rust Finish
Protective coating can be added to:
- Reduce rust runoff
- Stabilize color
- Protect nearby materials
Wall Panel Installation Structures
Corten wall panels are commonly installed using:
- Steel support frames
- Hidden fastener systems
- Bolt-fixed systems
- Ventilated facade structures
The installation gap is important because corten steel expands and contracts with temperature changes.
Common Applications of Corten Metal Wall Panels
Architectural Exterior Walls
- Commercial building facades
- Shopping centers
- Office buildings
- Cultural centers
Landscape and Garden Walls
- Decorative landscape screens
- Garden boundary walls
- Outdoor feature walls
Interior Decoration
- Industrial-style interior walls
- Restaurant decoration
- Hotel feature panels
Public Architecture
- Museums
- Art galleries
- Urban landscape structures
