The difference is as follows:
1, the process of refining, in a continuous unit with cold-rolled strip, galvanized steel (galvanized and hot-dip galvanized) as the substrate, through the surface pretreatment (degreasing and chemical treatment), by roller coating method One or more layers of liquid paint, after baking and cooling the resulting plate is coated steel. As the coating can have a variety of different colors, customarily coated steel plate is called color coated steel plate. Color coated board has a strong hardness and flexibility. Its layer of anti-scratch, friction, collision and other mechanical effects.
The layer of the color coated plate is deformed together with the substrate and does not have the ability to break. The color plate begins at the end of the production, and the performance of the original layer is reduced to the interval between the time it is necessary to maintain its protection against the substrate.
2, color steel plate is cold-rolled steel plate as the substrate, its degreasing, phosphating and salt treatment, under the protection of nitrogen under the double-sided galvanized, and then applied to the primer firmly bonded chemical conversion Film, and then coated with epoxy primer, and finally coated with chemical-resistant color finish, it is so shaped.
