Corten Steel Sheets For Sale
Corten steel sheets for sale are commonly available in thicknesses from 0.8 mm to 6 mm, making them suitable for architectural, decorative, and light structural applications. Thin gauges are preferred for cladding and design projects, while thicker sheets offer improved strength for outdoor industrial use. Choosing the right corten sheet thickness depends mainly on whether the application focuses on appearance, fabrication, or structural performance.
- Description
Corten steel sheets for sale are usually supplied as weathering steel flat products used for architectural cladding, landscape design, containers, and structural fabrication. Compared with thicker corten plates, corten steel sheets mainly refer to thinner gauges that are easier to bend, cut, and weld for decorative or light structural applications.
The most common grades include ASTM A606 Type 4, ASTM A588, and equivalent weathering steel grades such as S355J2W and Q355NH. The main difference between sheet and plate is usually the thickness range.
Standard Thickness of Corten Steel Sheets
Corten steel sheets are generally available in thin and medium gauges. For commercial supply, the most common thickness range is:
| Thickness (mm) | Thickness (inch) | Common Use |
|---|---|---|
| 0.8 mm | 0.031″ | Decorative panels |
| 1.0 mm | 0.039″ | Wall cladding |
| 1.5 mm | 0.059″ | Garden screens |
| 2.0 mm | 0.079″ | Landscape edging |
| 3.0 mm | 0.118″ | Exterior panels |
| 4.0 mm | 0.157″ | Structural covering |
| 5.0 mm | 0.197″ | Container fabrication |
| 6.0 mm | 0.236″ | Heavy sheet applications |
In most markets:
- Below 6 mm is usually called corten steel sheet
- Above 6 mm is often classified as corten steel plate
This naming convention depends on suppliers and local steel standards.
Common Sheet Width and Length
Corten sheets are typically supplied in standard mill dimensions.
| Width | Length |
|---|---|
| 1000 mm | 2000 mm |
| 1219 mm | 2438 mm |
| 1250 mm | 2500 mm |
| 1500 mm | 3000 mm |
| 2000 mm | 6000 mm |
Custom cutting services are often available for laser cutting, bending, and fabrication according to project drawings.
Why Thickness Selection Matters
The thickness of corten steel sheets affects both appearance and service life.
Thin Sheets (0.8–2 mm)
These are mainly used for:
- Decorative facades
- Exterior wall panels
- Rusted art panels
- Garden edging
- Signage
Thin corten sheets develop rust quickly and are easier to shape into custom designs.
Medium Sheets (3–6 mm)
These are commonly used for:
- Structural wall cladding
- Outdoor partitions
- Retaining walls
- Industrial enclosures
- Shipping container panels
Medium thickness provides better flatness, strength, and longer service life in outdoor environments.
Corten Sheet vs Corten Plate Thickness
| Product Type | Typical Thickness |
|---|---|
| Corten Sheet | 0.8–6 mm |
| Corten Plate | 6–100 mm |
Sheet products are mainly used where flexibility and surface appearance are important, while plate products are selected for load-bearing structures.
Surface Condition
Corten steel sheets for sale are usually supplied in three surface conditions:
- Black steel surface — original mill finish
- Pre-rusted surface — accelerated oxidation treatment
- Weathered surface — naturally exposed patina finish
Pre-rusted corten sheets are popular for projects requiring immediate decorative rust appearance without waiting for natural oxidation.
