Q:How to distinguish between color-coated aluminum coil and color-coated coil

The main difference between a color-coated aluminum coil and a color-coated coil lies in the substrate and application field. ‌

Color-coated aluminum coil is based on aluminum, and the surface of the aluminum substrate is colored by a paint-coating process. Common ones are fluorocarbon color-coated aluminum coil and polyester color-coated aluminum coil. This material has become an ideal choice for modern building exterior walls and interior decoration due to its high strength and non-deformation characteristics. At the same time, it provides a variety of color and pattern customization services, making the building appearance more personalized and maintaining the durability and low maintenance cost of the material. ‌
The substrate of the color-coated coil is generally a cold-rolled plate, and the surface of the steel plate is coated by a coating process. Common coatings include epoxy resin, polyester, etc. The color-coated coil is widely used in construction, home appliances, and other fields due to its good corrosion resistance, fire resistance, and low maintenance cost. ‌

Color-coated aluminum coils and color-coated steel coils also have different performances. For example, color-coated aluminum coil can form an aluminum oxide film in the atmosphere to prevent further corrosion, while color-coated steel coil is prone to corrosion and rust under the erosion of humid air and rain and snow, especially at the joints.
