Color coated board

The basic concept of color coated steel plate is to use cold rolled strip steel and galvanized strip steel (electro galvanizing and hot galvanizing) as substrates on a continuous production line, undergo surface pretreatment (degreasing and chemical treatment), apply one or more layers of liquid coating by roller coating method, and then bake and cool to obtain the coated steel plate. Currently, there are back (bottom) paint and top (front) paint coatings in China. Generally, in China, there is one layer of back paint and two layers of top paint, while in foreign business, there are two layers of back paint. Due to the fact that coatings can come in various colors, it is customary to refer to coated steel plates as colored coated steel plates.
