Common specifications of aluminized zinc coils mainly include thickness, width, coating weight, coil weight, and inner diameter. They are widely used in construction, home appliances, and industrial manufacturing. The following are core specification parameters compiled from mainstream market information:
Common Thickness Specifications
The substrate thickness of aluminized zinc coils is typically between 0.3mm and 3.0mm. Common specifications include:
- 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.8mm, 1.0mm, 1.2mm, 1.5mm, 2.0mm, 3.0mm, etc. Thinner or thicker specifications can be customized for special applications, such as 0.13mm and up.
Application Scenarios Reference:
- Thin specifications (0.3–0.6mm): Suitable for home appliance casings, interior decoration, and ventilation ducts;
- Thick specifications (0.8mm and above): Primarily used in building roofs, walls, structural components, and other load-bearing or high-durability applications.
Common Width Specifications
Standard widths generally range from 600mm to 1500mm. Common widths include:
- 700mm, 800mm, 900mm, 1000mm, 1200mm, 1250mm, 1260mm, 1500mm, etc.
Common export widths: 914mm, 1219mm, 1250mm. Some manufacturers support custom-made non-standard widths, but production equipment limitations must be considered.
Coating Weight (Zinc Layer Grams)
Coating weight is a key indicator of corrosion resistance, measured in g/m² (grams per square meter of aluminum-zinc alloy). Common specifications include:
- 60g/m², 90g/m², 100g/m², 120g/m², 150g/m², 180g/m². High-zinc coatings can reach 280g/m², suitable for extremely corrosive environments.
