Date of release:2019-03-07 Author: Click:

In the continuous unit, cold rolled strip, galvanized strip color coated plate quoted price (galvanized and hot galvanized) as the base plate, after surface pretreatment (degreasing and chemical treatment), with roll coating method, coated with one or more layers of liquid paint, after baking and cooling, the plate is coated steel plate. Because the coatings can be of various colors, it is customary to call coated steel sheets color coated steel sheets. Because the coating is carried out before the steel plate forming process, it is called pre-coated steel plate in foreign countries.

Technological process

The color coated steel plate is a product made of cold rolled steel plate and galvanized steel plate by surface pretreatment (degreasing, cleaning, chemical conversion), continuous coating (roll coating), baking and cooling.

The main production processes of the common two-coat and two-bake continuous color coating unit are uncoiling, pretreatment, coating, baking, post-treatment and coiling.

Product uses:

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. It is reported that the service life of the coated steel plate is 50% longer than that of the galvanized steel plate.
