Weathering steel coil (also known as atmospheric corrosion-resistant steel coil) is commonly available in a wide range of thicknesses. The specific thickness selection depends on the application and industry standards. The following are common thickness specifications:
1. Conventional Thickness Range
Thin Plate: 0.5mm to 3.0mm
(Commonly used for lightweight structures, decoration, and home appliance panels)
Medium Plate: 3.0mm to 6.0mm
(Suitable for building envelopes, containers, and vehicle manufacturing)
Thick Plate: 6.0mm to 12.0mm or thicker
(Used for load-bearing structures such as bridges, towers, and heavy machinery)
2. Typical Standard Thicknesses
1.0mm, 1.2mm, 1.5mm, 2.0mm, 2.5mm
3.0mm, 4.0mm, 5.0mm, 6.0mm, 8.0mm, 10.0mm
3. Related Standard References
National Standard (GB/T): For example, the thickness specifications listed in GB/T 4171, "Weathering-Resistant Structural Steel."
Industry Requirements: 2.0-6.0mm is commonly used in the construction industry, while 1.5-4.0mm may be used in transportation.
4. Special Requirements
Some projects may require custom non-standard thicknesses (e.g., 12mm or greater), requiring a design that considers both strength and corrosion resistance.
Note:
The material of the weather-resistant coil (e.g., SPA-H, 09CuPCrNi-A, etc.) will also influence thickness selection.
Specific standards (e.g., ASTM A606, EN 10025-5, etc.) or customer specifications should be referenced during actual procurement.
