The coated steel plate can be made into various textures because its surface is covered with a special film layer. This film layer is composed of polyester resin, polyvinyl chloride, polypropylene and other materials, and has good weather resistance, wear resistance and corrosion resistance. In the manufacturing process, different textures and colors can be printed on the film layer, and then the film layer and the steel plate are combined to form a coated steel plate with various textures. This technology can not only improve the aesthetics of the steel plate, but also increase the durability and corrosion resistance of the steel plate, and is widely used in architectural decoration, home decoration and other fields.
