Corten sheet refers to weathering steel sheets and plates 专为耐大气腐蚀而设计. These products are widely used in construction, 园林绿化, 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, 宽度, 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:

类别 厚度范围 产品类型
薄板 0.5 – 3.0 毫米 Cold rolled sheet
Medium sheet/plate 3.0 – 20 毫米 Hot rolled plate
厚板 20 – 100 毫米 厚板
  • Thin sheets are mainly used for decorative panels and cladding
  • 中等厚度 (such as 3–10 mm) is the most commonly used range
  • Thick plates are used in heavy structural applications

2. 标准宽度和长度

Corten sheets are typically produced in standard sizes but can also be customized.

Common Widths

  • 1000 毫米
  • 1219 毫米 (4 英尺)
  • 1250 毫米
  • 1500 毫米
  • 2000 毫米

Common Lengths

  • 2000 毫米
  • 2400 毫米
  • 3000 毫米
  • 6000 毫米

Typical Sheet Size Combinations

厚度 宽度 长度
1.5 – 3 毫米 1000 / 1219 / 1250 毫米 2000 / 2400 毫米
3 – 10 毫米 1250 / 1500 毫米 2500 / 3000 毫米
10 – 20 毫米 1500 / 2000 毫米 3000 / 6000 毫米

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

  • 耐候钢A (ASTM A242 Type 1)
  • 耐候钢 B (ASTM A588)

EN Standard Grades

  • S355J0WP
  • S355J2W
  • S355J2WP

GB Standard Grades (中国)

  • Q235NH
  • Q345NH
  • Q295GNH

4. Differences Between Main Grades

年级 标准 主要特点 应用
耐候钢A ASTM A242 Better atmospheric corrosion resistance Architectural use
耐候钢 B ASTM A588 强度更高 Structural use
S355J2W 在 10025-5 Balanced strength and toughness 建造
Q345NH 国标 Good weldability and strength General engineering

5. Supply Conditions and Forms

Corten sheets are usually supplied in the following conditions:

  • 热轧 (most common for ≥3 mm)
  • Cold rolled (for thin sheets ≤3 mm)
  • Pickled or shot blasted surface
  • Pre-weathered (optional for uniform rust appearance)
