Color-coated steel plates are made on a continuous unit using cold-rolled strip steel and galvanized strip steel (electro-galvanized and hot-dip galvanized) as the base plate. After surface pretreatment (degreasing and chemical treatment), a layer of coated steel plate is applied by roller coating. Or multiple layers of liquid paint, baked and cooled into a sheet.
Since the coating can have various colors, it is customary to call coated steel plates color-coated steel plates. And because the coating is carried out before the steel plate is formed and processed, it is called pre-coated steel plate abroad.
Color-coated steel plate is an organic coating applied to the surface of steel. It has the advantages of beautiful appearance, bright colors, high strength, good corrosion resistance, and convenient processing and molding. It can also enable users to reduce costs and reduce pollution.
Since the establishment of the first continuously coated steel plate line in the United States in 1935, color-coated steel plates have been widely used. There are many varieties of color-coated plates, about more than 600 types. Color-coated plates have the advantages of both organic polymers and steel plates. It has the good colorability, formability, corrosion resistance, and decorative properties of organic polymers, as well as the high strength and easy processability of steel plates. It can easily be processed by stamping, cutting, bending, deep drawing, etc. This makes products made of organically coated steel plates have excellent practicality, decoration, processability and durability.
