Color coating steel is cold rolled steel sheet and galvanized steel substrate, after surface pretreatment (degreasing, cleaning, chemical conversion treatment), with the method of continuous coated with paint (roller coating method), after baking and cooling and manufactured products.The main production process of the common two-coating continuous color coating unit is: opening, pretreatment, coating, baking, post-treatment and coiling.
Color coated steel plate type:
It is a cold rolled base plate color coated steel plate.
The color board produced by cold rolling base plate has a smooth and beautiful appearance, and has the processing property of cold rolling plate.But any small scratch on the surface of the coating would expose the cold rolled substrate to the air, causing it to rust quickly.Therefore, such products can only be used for temporary isolation measures with low requirements and for indoor materials.
Hot dip galvanizing color coated steel plate.
The product of coating organic coating on hot dip galvanized steel plate is hot dip galvanized coating.In addition to the protective effect of zinc, the organic coating on the surface has the effect of isolation and protection against rust, and the life is longer than that of galvanized sheet.The zinc content of the hot-dip galvanized substrate is generally 180g/m2 (double-sided), and the maximum galvanizing amount of the hot galvanized substrate is 275g/m2.
It is hot - plated aluminum zinc coated board.
