Prepainted Galvanized steel coil(Color coated steel coil) is in a continuous unit in cold-rolled steel strip, galvanized steel (galvanized and Galvanized) as substrate, after surface pretreatment (degreasing and chemical treatment), method for roll coating, coated with a layer or layers of liquid paint, after baking and cooling the sheet.
In a continuous unit in cold-rolled steel strip, galvanized steel (galvanized and Galvanized) as substrate, after surface pretreatment (degreasing and chemical treatment), method for roll coating, coated with a layer or layers of liquid paint, after baking sheet and the cooling is coated steel. Since the coating can be of various colors, the coated steel is customarily referred to as a color coated steel plate. Also, because the coating is made before the steel plate forming process, in foreign countries, this is called pre coated steel plate.
Color coated steel plate is a kind of organic coating on steel surface, it has the advantages of beautiful appearance, bright color, high strength, good corrosion resistance, easy molding, but also allows users to reduce costs and reduce pollution.
