The traditional coating is divided into several kinds, among which the fluorocarbon coating is the best, which could stay antiseptic for 20 years. The color steel plates we often see are the sheet materials machined with thickness of 50-100mm. They consist of padding in the middle and color plates of two sides. For the thickness of color steel plate, there are three kinds including 0.4mm, 0.5mm, 0.6mm. The padding in the middle could be polyurethane, rock wool, foamed plastic and etc. Because of the special profile, the plant built by color steel plates or building built with steel frame construction could be completed quickly. The substrate of color steel plate include cold rolling band, hot galvanizing band and electroplated zinc base plate. The coating variety could be divided into polyester, silicone modification polyester, segregation polyvinyldifluoride and plastisol. The surface states of color precoated steel could be divided into coated plate, matrixes for embossing, and print-coating plate.
The difference between color steel and plastic steel is the constitute of the material. The color steel is widely used in building and traffic. For the building, the color steel is mainly used in steel construction workshop, steel frame construction building, mobile house, modular construction building, energy efficient buildings，airport, storage, and etc. The color steel could attract the magnet. In strict significance, the color steel and plastic steel could not be differentiated from the aspects of metallic character and surface treatment.
