Corten Sheet
Corten sheets are available in a wide range of толщина, ширина, и длины, making them suitable for diverse applications from decorative cladding to heavy structural use. Общие оценки, такие как Кортен А, Кортен Б, S355J2W, and Q345NH provide different balances of corrosion resistance and mechanical strength.
- Описание
Corten sheet refers to weathering steel sheets and plates designed for atmospheric corrosion resistance. These products are widely used in construction, ландшафтный дизайн, 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, ширина, 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:
| Категория | Диапазон толщины | Product Type |
|---|---|---|
| Тонкий лист | 0.5 – 3.0 мм | Холоднокатаный лист |
| Medium sheet/plate | 3.0 – 20 мм | Горячекатаный лист |
| Толстая пластина | 20 – 100 мм | Тяжелая пластина |
- Thin sheets are mainly used for decorative panels and cladding
- Средняя толщина (such as 3–10 mm) is the most commonly used range
- Thick plates are used in heavy structural applications
2. Стандартная ширина и длина
Corten sheets are typically produced in standard sizes but can also be customized.
Common Widths
- 1000 мм
- 1219 мм (4 футы)
- 1250 мм
- 1500 мм
- 2000 мм
Common Lengths
- 2000 мм
- 2400 мм
- 3000 мм
- 6000 мм
Typical Sheet Size Combinations
| Толщина | Ширина | Длина |
|---|---|---|
| 1.5 – 3 мм | 1000 / 1219 / 1250 мм | 2000 / 2400 мм |
| 3 – 10 мм | 1250 / 1500 мм | 2500 / 3000 мм |
| 10 – 20 мм | 1500 / 2000 мм | 3000 / 6000 мм |
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
- Кортен А (ASTM A242 Type 1)
- Кортен Б (АСТМ А588)
EN Standard Grades
- S355J0WP
- S355J2W
- S355J2WP
GB Standard Grades (Китай)
- Q235NH
- Q345NH
- Q295GNH
4. Differences Between Main Grades
| Оценка | Стандартный | Ключевая особенность | Приложение |
|---|---|---|---|
| Кортен А | АСТМ А242 | Better atmospheric corrosion resistance | Architectural use |
| Кортен Б | АСТМ А588 | Более высокая прочность | Structural use |
| S355J2W | В 10025-5 | Balanced strength and toughness | Строительство |
| Q345NH | ГБ | Good weldability and strength | General engineering |
5. Supply Conditions and Forms
Corten sheets are usually supplied in the following conditions:
- Горячекатаный (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
