Coaed steel sheet has light weight, beautiful appearance, good anticorrosion performance and can be directly processed. It provides a new raw material for construction, shipbuilding, vehicle manufacturing, furniture and electrical industries, and has played a good role in replacing wood with steel, efficient construction, energy saving and pollution prevention.

In addition to zinc protection, the organic coating on the zinc layer acts as a covering and isolation function for the color coated steel plate with galvanized steel plate as its base plate, which can prevent the steel plate from rusting and has a longer service life than that of the galvanized steel plate.
