When we use cold-rolled strip steel and galvanized steel coil (galvanized and hot galvanized) as the base board to process with a continuous unit, adopt surface preparation (degreasing and heat treatment), and apply one or more layers of liquid paint with roller coating method, finally we execute baking and cooling, then the obtained sheet is coated steel. Since the coating may have a variety of colors, the coated steel is customarily called the color coated steel.
