This is a processing of coating sheet with organic paint and then overprint multiple patterns. The coated sheet has good characteristic such as processability, corrosion resistance, decoration, as well high strength and good deformability. It is deep working product and energy-saving material. Recent years, high quality and multi-function color coating strip is developed rapidly and the color steel plate with high corrosion resistance, high deformability, fingerprint resistance and bacteria resistance etc will be good prospect.
