Color-coated rolls have light weight, beautiful appearance and good corrosion resistance. They can be processed directly. The colors are generally divided into gray, sea blue and brick red. They are mainly used in advertising, construction, home appliance industry, electrical appliance industry, furniture industry and transportation. Industry.
The paint used for color-coated rolls should be selected from suitable resins according to the use environment, such as polyester silicon modified polyester, polyvinyl chloride plastisol, polyvinylidene chloride and so on. The user can choose according to the purpose.
Hot-dip galvanized substrate
The product obtained by coating the organic paint on the hot-dip galvanized steel sheet is the hot-dip galvanized color-coated steel sheet. In addition to the protective effect of zinc, the hot-dip galvanized color-coated sheet also has an organic coating on the surface to insulate and protect and prevent rust, and its service life is longer than that of the hot-dip galvanized sheet. The zinc content of the hot-dip galvanized substrate is generally 180g/m2 (double-sided), and the maximum zinc content of the hot-dip galvanized substrate for building exterior is 275g/m2.
Electro-galvanized substrate
The electro-galvanized sheet is used as the substrate, and the product obtained by coating with organic paint and baking is electro-galvanized color-coated sheet. Because the zinc layer of the electro-galvanized sheet is thin, the zinc content is usually 20/20g/m2, so this product is not suitable for use Make walls, roofs, etc. outdoors. But because of its beautiful appearance and excellent processing performance, it can be mainly used for home appliances, audio, steel furniture, interior decoration, etc.
