Caitu production techniques pioneered in the United States in 1927, 1936 and completed the first set of painted steel production unit, in 1955 built the world's first set of strip continuous color coating production unit. 1960s, the rapid development of color coated production in North America, Europe, Japan and particularly rapid development, currently the world except China has more than 400 sets of painted units, total capacity of about 14 million t / a. Color coating has been widely used in construction, home appliances, furniture, appliances and other fields.

In the first pass through the process section strip lye cleaning, rinsing, drying, de-oil decontamination, and then surface pretreatment (chromium or phosphate, dry, strip into the coating chamber by roller coating machine dip stick the liquid coating, the coated roll coating applied to the strip material, the lower surface of Buying color-coated roll, coated with a wet film of the strip into the heating and baking ivory color coating curing oven, the temperature from low to high, and the wet complete evaporation of the solvent in the film out, and the solvent-containing exhaust gases to the incinerator deal. strip cured coating is subjected to a quenching water cooling, hot air drying.
