Commonly used coatings for color coated steel sheets are polyester (BHP XRW coating system, Baosteel JZ, Korea PGS, Taiwan PE), followed by silicon resin (PSS), fluororesin (PVDF) and the like.

The coating structure is divided into two coatings and two coatings, and the coating thickness is generally 20-25μ on the surface and 8-10μ on the back surface.
