코르텐 시트
Corten sheets are available in a wide range of 두께, 너비, 및 길이, making them suitable for diverse applications from decorative cladding to heavy structural use. 다음과 같은 일반적인 등급 코르텐 A, 코르텐 B, S355J2W, and Q345NH provide different balances of corrosion resistance and mechanical strength.
- 설명
Corten sheet refers to weathering steel sheets and plates 대기 내식성을 위해 설계됨. These products are widely used in construction, 조경, 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, 너비, 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:
| 범주 | 두께 범위 | 제품 유형 |
|---|---|---|
| 얇은 시트 | 0.5 – 3.0 mm | 냉간 압연 시트 |
| Medium sheet/plate | 3.0 – 20 mm | 열간압연판 |
| 두꺼운 판 | 20 – 100 mm | 후판 |
- Thin sheets are mainly used for decorative panels and cladding
- 중간 두께 (such as 3–10 mm) is the most commonly used range
- Thick plates are used in heavy structural applications
2. 표준 너비 및 길이
Corten sheets are typically produced in standard sizes but can also be customized.
공통 너비
- 1000 mm
- 1219 mm (4 피트)
- 1250 mm
- 1500 mm
- 2000 mm
일반적인 길이
- 2000 mm
- 2400 mm
- 3000 mm
- 6000 mm
Typical Sheet Size Combinations
| 두께 | 너비 | 길이 |
|---|---|---|
| 1.5 – 3 mm | 1000 / 1219 / 1250 mm | 2000 / 2400 mm |
| 3 – 10 mm | 1250 / 1500 mm | 2500 / 3000 mm |
| 10 – 20 mm | 1500 / 2000 mm | 3000 / 6000 mm |
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
- 코르텐 A (ASTM A242 Type 1)
- 코르텐 B (ASTM A588)
EN Standard Grades
- S355J0WP
- S355J2W
- S355J2WP
GB Standard Grades (중국)
- Q235NH
- Q345NH
- Q295GNH
4. Differences Between Main Grades
| 등급 | 기준 | 주요 특징 | 애플리케이션 |
|---|---|---|---|
| 코르텐 A | ASTM A242 | Better atmospheric corrosion resistance | 건축학적 사용 |
| 코르텐 B | ASTM A588 | 더 높은 강도 | 구조적 사용 |
| S355J2W | 안에 10025-5 | Balanced strength and toughness | 건설 |
| Q345NH | GB | Good weldability and strength | General engineering |
5. Supply Conditions and Forms
Corten sheets are usually supplied in the following conditions:
- 열간압연 (most common for ≥3 mm)
- Cold rolled (for thin sheets ≤3 mm)
- Pickled or shot blasted surface
- Pre-weathered (optional for uniform rust appearance)
