Background

The color coated steel plate is a composite metal plate which uses galvanized steel plate or cold-rolled steel plate as a substrate and is coated with various protective and decorative coatings after surface treatment, and is also called as a color organic coated steel plate. The color coated steel plate has the structural layers from inside to outside, namely a cold-rolled plate, a zinc coating, a chemical conversion layer, a primary coating (primer) and a finish coating (front and back finish). The plate has novel surface color, strong adhesive force, good rust resistance and decoration and good processing performance, and can be cut, bent, drilled, riveted, curled and the like. Common coatings are divided into three categories, namely inorganic coatings, organic coatings and composite coatings;

when the existing color coating steel plate is subjected to embossing operation, a zinc coating on the surface layer of a substrate is damaged, so that the corrosion resistance of the color coating steel plate is damaged, and the service life of the color coating steel plate is reduced; in addition, the general color coated steel plate has poor light reflection capability and can absorb more light energy, thereby limiting the use in the field with high light reflection requirement and having certain limitation.
