       The steel sheet coated with an organic coating, the coating can have a variety of Color, color coated steel hence the name, abbreviated coating, also known as organic coated steel. Because color coated steel plate molding is first coated before coating, in a foreign country, also known as pre-coated steel. Color-coated organic coating covering the isolation effect can be Prevent rusting steel, longer service life.
       The Board has a color-coated cold-rolled Board, galvanized Board, electro-galvanized Board, hot galvanized Board. Color-coated finish coating types can be divided into: polyester, silicon Modified polyesters, poly-vinylidene fluoride, polyester, and high durability.
       Color-coated Color can have a variety, such as orange, yellow milk, deep sky blue, navy, crimson, brick red, ivory, porcelain blue.
       Color-coated surface state can be divided into normal coated sheet, Embossing steel coils, printing plate.
       Caitu market uses mainly for construction, household appliances and traffic transmission.
