The main coatings are PE coating and PVDF coating. The front film thickness is 25-28 um and the back film thickness is 15-18 um. Fluorocarbon coating has excellent wear resistance, impact resistance and has superior anti-fading and anti-ultraviolet performance in the harsh environment. PE coating hasgood gloss and smoothness, as well as superior texture, and three-dimensionality.

The type and thickness of the coating depends on the balance between cost-effectiveness and performance. The service life depends on many factors, including outdoor exposure conditions, cleaning and keeping the surface free from long-term contact with corrosive materials. Proper maintenance of its surface can extend its service life.

Haomei color coated aluminum coil adopts unique pretreatment, which uses alternating current of sulfuric acid electrolyte to form an aluminum oxide film on the aluminum surface. It is of a flexible porous structure that has excellent paint adhesion and good corrosion resistance. This pre-treatment is non-toxic, which does not contain any heavy metal.
