Function of color coated aluminum sheet coating layers

　　The color coated aluminum sheet is obtained by coating a hot-dip galvanized sheet, aluminum-zinc plate or electro-galvanized sheet with one or several layers of paint are applied on the surface, and the paints are then baked and cured. That’s how its name comes. In addition to protecting the zinc layer, the coating on the zinc layer also serves to cover and protect the aluminum plate from rusting, and the service life is about 1.5% of the galvanized steel strip.

　　The main uses of the color coated aluminum sheet are as follows:

　　The color coated sheet is light in weight, beautiful in appearance, good in corrosion resistance and can be directly processed. The colors are generally divided into gray, sea blue and brick red. The sheet is mainly used in advertising, construction, home appliances, electrical appliances, furniture, transportation and other industries. You can choose the right resin according to different environments and usages.

　　Functions of different coating structures for color coated aluminum coil sheet are as below:

　　1. Single-layer back paint is corrosion-resistant and scratch-resistant, but it has good adhesion and is mainly used for sandwich panels.

　　2. The back paint has good corrosion resistance, scratch resistance and processability. It has good adhesion and is suitable for single-layer shaped plates and sandwich panels.

　　3. Double-layer back paint has good corrosion resistance, scratch resistance and formability. Mainly used for single-layer laminates, it is not suitable for sandwich panels due to poor adhesion.

　　3000 and 5000 series of color coated aluminum coil sheets are widely used in aluminum-plastic panels, honeycomb panels, thermal insulation panels, aluminum curtain walls, shutters, roller shutters, aluminum magnesium manganese because of their light weight, bright color, easy processing and rusting. Roofing systems, aluminum ceilings, household appliances, drainage pipes, aluminum cans and many other fields. If you have relative purchase requirements, welcome to contact us for more information!
