What is the color-coated aluminum?
Color-coated aluminum is a material with a painted surface layer applied to aluminum coils through processes such as cleaning, chroming, roller coating, and baking.
The coating protects the aluminum from UV radiation, corrosive gases, and microbial effects, extending its service life.
It is widely used in construction, decoration, and other industries in the form of sheets or coils.

Advantages and Benefits
Aluminum forms a natural oxide film that protects against further oxidation and corrosion.
Coated with fluorocarbon or polyester paint, coated aluminum sheets are fingerprint-resistant, anti-static, and scratch-resistant.
The surface is clean, free from oil contamination, and offers bright, stable colors with excellent decorative properties.
With a density one-third that of steel, aluminum reduces the load on supporting structures, making it suitable for long-span buildings.
The addition of metals like magnesium and manganese enhances the strength and rigidity of aluminum alloy sheets.
Coated aluminum have a high recycling value, making them more sustainable and cost-effective compared to ordinary steel plates.
Quality Control and Testing
- Coating Thickness: Measured using a magnetic thickness gauge.
- Color Difference: Detected using a colorimeter.
- Gloss: Measured with a gloss meter (tolerance ±5).
