What are the types of color-coated steel plates?

Color-coated steel plate is referred to as color-coated steel plate. This kind of plate has novel surface color, strong adhesion, good rust resistance and decorative properties, and good processing performance. Therefore, it is widely used in building exterior wall cladding, roof panels, corrugated boards, etc. Waterproof and air-proof panels, corrosion-resistant equipment and components, furniture, car casings, water shields, etc. Depending on the structure, color-coated steel plates can be divided into the following types:
1. Coated steel plate
Galvanized steel is used as the base, and the front and back are coated to ensure its corrosion resistance. The first layer on the front is a primer, usually an epoxy primer because it has strong adhesion to metal, and the back is also coated with epoxy resin or acrylic resin; the second layer (surface layer) used to be alkyd resin, usually with Polyester paint or acrylic resin paint.
2. PVC steel plate
The PVC layer is thermoplastic, and the surface can be thermally processed. For example, embossing can make the surface richer in texture. It is also flexible and can be subjected to secondary processing such as bending. Its corrosion resistance is also relatively good. There are two types of PVC steel plates. One is produced by coating paste PVC, which is called coated PVC steel plate; the other is produced by pasting formed and printed or embossed PVC film on the steel plate, which is called film. PVC steel plate.
3. Insulation coated steel plate
Thermal insulation coated steel plate is to stick 15~17mm thick polystyrene foam or rigid polyurethane foam on the back of the color-coated steel plate to improve the performance of the coated steel plate. It is mainly used for places that require heat and sound insulation. special areas.
4. High durability coated steel plate
Taking advantage of the good aging resistance of fluoroplastics and acrylic resin, high-durability coated steel plates are used on the surface coating of steel plates to improve the durability and corrosion resistance of color-coated steel plates.
