Plate Corten Steel
Corten steel plates are available in a broad range of thicknesses and dimensions to meet different industrial and architectural needs:
- Thickness: 1.5 mm to 200 mm
- Width: up to 3500 mm+
- Length: up to 15000 mm+
- Description
Corten steel plates (weathering steel plates) are widely used in construction, landscaping, and structural engineering due to their corrosion resistance and long service life. They are typically supplied in hot-rolled condition and can be cut, welded, and fabricated according to project requirements.
Understanding the standard sizes and thickness ranges is essential for material selection, cost control, and fabrication efficiency.
Common Thickness of Corten Steel Plates
Corten steel plates are available in a wide range of thicknesses depending on application requirements.
Standard Thickness Range
| Category | Thickness Range |
|---|---|
| Thin Plate | 1.5 mm – 6 mm |
| Medium Plate | 6 mm – 25 mm |
| Thick Plate | 25 mm – 100 mm |
| Extra Thick Plate | 100 mm – 200 mm |
Key Insight:
- Thin plates are mainly used for decorative and architectural applications
- Medium and thick plates are used for structural and load-bearing purposes
Standard Plate Dimensions
Corten steel plates are commonly produced in standard mill sizes, but they can also be customized.
Common Width and Length
| Type | Width (mm) | Length (mm) |
|---|---|---|
| Standard Plate | 1000 – 2000 | 2000 – 6000 |
| Wide Plate | 2000 – 3000 | 6000 – 12000 |
| Custom Plate | Up to 3500+ | Up to 15000+ |
Typical Standard Sizes
- 1000 × 2000 mm
- 1220 × 2440 mm (common sheet size)
- 1500 × 3000 mm
- 2000 × 6000 mm
Weight Reference for Corten Steel Plates
Plate weight is calculated based on thickness and dimensions.
Example Weight Table (Theoretical)
| Thickness (mm) | Weight (kg/m²) |
|---|---|
| 2 mm | 15.7 |
| 5 mm | 39.25 |
| 10 mm | 78.5 |
| 20 mm | 157.0 |
| 50 mm | 392.5 |
Formula:
Weight (kg) = Thickness (mm) × Width (m) × Length (m) × 7.85
Common Grades of Corten Steel Plates
Corten steel plates are available in several international grades:
- EN standard: S355J0WP, S355J2W
- ASTM standard: A588, A242
- Other equivalents depending on region
Different grades may affect available thickness ranges and delivery conditions.
Delivery Conditions and Processing
Corten steel plates are typically supplied in:
- Hot rolled condition
