Color-coated plate is cold rolled steel strip in a continuous unit, galvanized steel (zinc plating and galvanizing) as substrate, after surface preparation (degreasing and chemical processing), roller coating, coated with a layer or multiple layers of liquid coatings, obtained after baking and cooling plate for coated steel sheets. Because the coating can come in all different colors, customarily called colored coating steel plate coated steel sheet. Since the coating is made prior to the steel plate processing abroad, this is called pre-coated steel sheet.
Prepainted steel sheet is an organic coating on steel surfaces, it is aesthetically pleasing, colorful, high strength, corrosion resistance, easy processing advantages, but also enables you to lower costs, reduce pollution.
From 1935 American established first article continuous coating plate line began, color coated plate get has widely application, currently color coated Board of varieties range, about over 600 species, color coated Board and organic polymer and plate both of advantages, both organic polymer of good coloring sex, and forming sex, and resistance corrosion sex, and decorative sex, and and has plate of high strength and vulnerable processing sex, can is easy to for stamping crop, and bent, and deep rushed, processing. Which makes organic coated steel products have excellent practical, decorative, workability, durability.
