Released on Oct. 08, 2018

The Color Coated Steel Sheet is an organic coating applied on the surface of the steel material, which has the advantages of beautiful appearance, bright color, high strength, good corrosion resistance, convenient processing and the like, and can also reduce cost and reduce pollution.

On the continuous unit, cold-rolled strip steel, galvanized strip steel (electro-galvanized and hot-dip galvanized) is used as the substrate, subjected to surface pretreatment (degreasing and processing), and coated with one or more layers of liquid by roller coating. The coating material obtained by baking and cooling is a coated steel sheet. Since the coating can have a variety of different colors, it is customary to refer to a coated steel sheet as a color coated steel sheet. Because the coating is carried out before the forming of the steel sheet, it is called pre-coated steel sheet abroad.

Since the establishment of the first continuous Color Coated Roofing Sheet line in the United States in 1935, color coated steel sheets have been widely used. At present, there are many varieties of color coated sheets, which are more than 600 kinds, and the advantages of color coated sheets and both organic polymers and steel sheets are The organic polymer has good colorability, moldability, corrosion resistance, decorativeness, high strength and easy processing of the steel sheet, and can be easily processed by punching, bending, deep drawing, and the like. This makes the products made of the organic coated steel sheet have excellent practicability, decoration, workability and durability.
