What is color coated steel plate? What are the categories of color coated steel plates?

Color coated steel sheet is galvanized or cold rolled steel as the base, the surface of which is then covered with various inner and outer decorative layers, divided into cold rolled sheet, galvanized layer, chemical transformation layer and so on. The surface of the sheet not only has a new color and strong adhesion, but also has strong processability, it can be cut, bent and drilled.
Color coated steel sheet can be divided into the following categories:

1, Painted steel plate

Painted steel sheet is galvanized steel as the main material, front and back painted, so that it has good corrosion resistance. Usually the first layer of primer, most epoxy primer, and the metal can have strong adhesion, the second layer is the surface layer, usually with polyester paint or acrylic resin paint.

2, PVC steel plate.

PVC steel refers to thermoplastic, the surface can not only heat treatment (such as embossing to make the surface texture richer), but also has very good flexibility (can be bent processing), at the same time it is also good corrosion resistance. PVC steel sheet in the market is divided into two kinds: PVC coated steel sheet and PVC steel sheet with film. Although PVC steel is a very good material, but its disadvantage is that the surface layer is easy to age, so after continuous technological innovation, now on the market appeared in PVC surface, and then add composite acrylic resin PVC steel, the service life is longer.

3, heat insulating steel sheet coating

Thermal insulation coated steel plate is in the steel plate with color coating on the back of 15-17mm thick polystyrene foam, rigid polyurethane foam and other materials that can play good heat and sound insulation.

4, High-strength coated steel plate

Because fluoroplastics and acrylic resins have aging resistance properties, they are added to the surface layer of coated steel plate, making the coated steel plate more durable and corrosion resistant.
