Corten Sheet
Corten sheets are available in a wide range of espessuras, larguras, e comprimentos, making them suitable for diverse applications from decorative cladding to heavy structural use. Notas comuns como Corten A, Corten B, S355J2W, and Q345NH provide different balances of corrosion resistance and mechanical strength.
- Descrição
Corten sheet refers to weathering steel sheets and plates designed for atmospheric corrosion resistance. These products are widely used in construction, paisagismo, and industrial fabrication due to their ability to form a stable protective rust layer.
Corten sheets are typically supplied in flat sheet or plate form, with various thicknesses, larguras, and lengths depending on application requirements.
1. Standard Thickness of Corten Sheets
Corten steel is available in a wide thickness range to meet different fabrication and structural needs:
| Categoria | Faixa de espessura | Tipo de produto |
|---|---|---|
| Folha fina | 0.5 – 3.0 milímetros | Cold rolled sheet |
| Medium sheet/plate | 3.0 – 20 milímetros | Hot rolled plate |
| Prato grosso | 20 – 100 milímetros | Prato pesado |
- Thin sheets are mainly used for decorative panels and cladding
- Espessura média (such as 3–10 mm) is the most commonly used range
- Thick plates are used in heavy structural applications
2. Largura e comprimento padrão
Corten sheets are typically produced in standard sizes but can also be customized.
Larguras Comuns
- 1000 milímetros
- 1219 milímetros (4 pés)
- 1250 milímetros
- 1500 milímetros
- 2000 milímetros
Comprimentos Comuns
- 2000 milímetros
- 2400 milímetros
- 3000 milímetros
- 6000 milímetros
Typical Sheet Size Combinations
| Grossura | Largura | Comprimento |
|---|---|---|
| 1.5 – 3 milímetros | 1000 / 1219 / 1250 milímetros | 2000 / 2400 milímetros |
| 3 – 10 milímetros | 1250 / 1500 milímetros | 2500 / 3000 milímetros |
| 10 – 20 milímetros | 1500 / 2000 milímetros | 3000 / 6000 milímetros |
Custom cutting and sizing are commonly available to meet project-specific requirements.
3. Common Grades of Corten Steel Sheets
Corten steel includes several international grades depending on standards and applications:
ASTM Standard Grades
- Corten A (ASTM A242 Type 1)
- Corten B (ASTM A588)
EN Standard Grades
- S355J0WP
- S355J2W
- S355J2WP
GB Standard Grades (China)
- Q235NH
- Q345NH
- Q295GNH
4. Differences Between Main Grades
| Nota | Padrão | Recurso -chave | Aplicativo |
|---|---|---|---|
| Corten A | ASTM A242 | Better atmospheric corrosion resistance | Architectural use |
| Corten B | ASTM A588 | Maior resistência | Structural use |
| S355J2W | EM 10025-5 | Balanced strength and toughness | Construção |
| Q345NH | GB | Good weldability and strength | General engineering |
5. Supply Conditions and Forms
Corten sheets are usually supplied in the following conditions:
- Laminado a quente (most common for ≥3 mm)
- Cold rolled (for thin sheets ≤3 mm)
- Pickled or shot blasted surface
- Pre-weathered (optional for uniform rust appearance)
6. Applications of Corten Sheets
