Corten Sheets For Sale
Corten sheets for sale are commonly supplied in grades such as ASTM A606, ASTM A588, S355J2W, SPA-H, and Chinese equivalents like Q355NH. Standard thickness ranges from 1.0 mm to 6.0 mm, with 2.0–3.0 mm being the most widely used for architectural and landscaping applications. Standard sheet sizes include widths from 1000 mm to 2000 mm and lengths up to 6000 mm, with full support for custom cutting and fabrication.
- Description
Corten sheets for sale refer to weathering steel sheet products widely used in architectural cladding, garden panels, containers, bridges, and outdoor structural applications. These sheets are designed to form a protective rust patina when exposed to outdoor environments, improving corrosion resistance and reducing maintenance requirements.
When purchasing corten steel sheets, buyers usually focus on two key factors: standard sizes (thickness and dimensions) and material grades (domestic and international standards).
Common Corten Steel Sheet Grades
Corten steel is produced under different standards worldwide, but all belong to weathering steel categories.
International Grades
- ASTM A606 Type 4 (thin sheet / decorative use)
- ASTM A588 (structural weathering steel)
- ASTM A242 (early weathering steel grade)
- EN S355J2W (European standard weathering steel)
- EN S355JOWP (improved corrosion resistance version)
- JIS SPA-H (Japanese weathering steel)
Chinese Equivalent Grades
- Q355NH (most commonly used export grade)
- Q235NH (lower strength weathering steel)
- Q295NH (medium strength grade)
- 09CuPCrNi-A (railway and container steel)
- Q450NQR1 (high-strength weathering steel)
Among these, Q355NH, ASTM A606, and ASTM A588 are the most commonly supplied corten sheet materials in international trade.
Common Thickness of Corten Sheets
Corten sheet metal is typically supplied in thin to medium gauges for fabrication and architectural use.
| Thickness | Application |
|---|---|
| 1.0 mm | Decorative panels, interior design |
| 1.5 mm | Garden screens, wall cladding |
| 2.0 mm | Outdoor decorative panels |
| 3.0 mm | Privacy screens, façades |
| 4.0 mm | Structural cladding panels |
| 5.0 mm | Heavy-duty outdoor fabrication |
| 6.0 mm | Thick sheet / transition to plate |
The most commonly purchased range is 2.0 mm to 3.0 mm, especially for architectural and landscape projects.
Standard Sheet Sizes
Corten steel sheets for sale are usually available in standard mill sizes, which can also be cut to custom dimensions.
Common Widths
- 1000 mm
- 1219 mm
- 1250 mm
- 1500 mm
- 2000 mm
Common Lengths
- 2000 mm
- 2438 mm
- 2500 mm
- 3000 mm
- 6000 mm
Custom cutting, laser cutting, and fabrication are also commonly provided for engineering and design projects.
Common Product Forms
Corten steel sheets are supplied in different surface and processing conditions:
- Black (mill finish) corten sheet
- Pre-rusted corten sheet
- Weathered natural patina sheet
- Laser-cut decorative panels
- Perforated corten sheets
Pre-rusted and laser-cut sheets are especially popular for architectural decoration and garden design.
Application-Oriented Specification Selection
Different thicknesses and grades are selected based on application needs:
- Thin sheets (1.0–2.0 mm): decorative wall panels, interior design
- Medium sheets (2.0–3.0 mm): garden screens, façade cladding
- Thick sheets (4.0–6.0 mm): structural landscaping, outdoor partitions
For most architectural projects, Q355NH / ASTM A606 in 2–3 mm thickness is the most common combination.
