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.
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 service life is longer than that of hot galvanizing plate.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.
According to the requirements, hot aluminized zinc plate can also be used as color coating substrate (55% ai-zn and 5% ai-zn).
Electric zinc coated board.
Electricity galvanized sheet as the substrate, coated with organic coating baking products for electric galvanized caitu, due to the electric galvanized zinc layer thin, usually zinc as 20/20 g/m2, so the product is not suitable for use in making outdoor wall, roof, etc.However, because of its beautiful appearance and excellent processing performance, it is mainly used for home appliances, acoustics, steel furniture, interior decoration and so on.
Coating is a kind of flow state or powder state organic matter, coating on the bottom material can dry solidify form a layer of thin film, evenly cover and good adhesion.Its main properties are protection (such as moisture resistance, water resistance, weather resistance, chemical resistance, etc.) and decoration (with various colors and gloss).
