What are the base plate types of color coated plate

Abstract: Color coated plate, also known as color steel plate, is a cold-rolled steel plate and galvanized steel plate as the base plate, after surface pretreatment, using roll coating + baking process, in a continuous method coated with paint, after baking and cooling products. Color coated plate base plate types are hot dip galvanized color coated plate, electric galvanized color coated plate, hot aluminum plating zinc color coated plate, cold rolled base plate color coated plate and so on. The following is to introduce the production process of color steel plate, take a look at it together.

What are the base plate types of color coated plate

Color coated board, also known as coating board, is based on metal coil as the base material, coated or laminated on the surface of various organic coatings or plastic film made of building materials, color coated board substrate types are mainly:

1. Cold rolled substrate

The color plate produced by cold rolled substrate has smooth and beautiful appearance, and has the processing property of cold rolled plate; But any small scratch on the surface coating will expose the cold-rolled substrate to air, which will quickly cause red rust to form on the exposed iron. Therefore, such products can only be used for temporary isolation measures and indoor materials, which are not very demanding.

2, hot dip galvanized color coated steel plate

The organic coating on the hot dip galvanized steel sheet product is hot dip galvanized color coated board. In addition to the protective effect of zinc, the organic coating on the surface also plays the role of isolation protection and rust prevention, and the service life is longer than that of hot galvanized sheet. The zinc content of hot-dip galvanized substrate is generally 180g/㎡ (double-sided), and the maximum galvanizing amount of hot-dip galvanized substrate for external construction is 275g/㎡.

3, hot plating aluminum zinc color coated plate

The organic coating on the hot aluminized zinc plate is the product of hot galvanized color coated plate. The content of aluminum zinc in the hot aluminized zinc plate is 55%AI-Zn and 5%AI-Zn.

4, electric galvanized color coating board

Electrogalvanized plate as the base plate, coated with organic coating baking products for electric galvanized color coated plate, because the zinc layer of electrogalvanized plate thin, usually zinc content is 20/20g/m2, so the product is not suitable for use in outdoor production of walls, roofs, etc. But because of its beautiful appearance and excellent processing properties, it is mainly used in household appliances, audio, steel furniture, interior decoration and so on.

Two, what is the use of color coating board

The use of galvanized steel plate for the color coated steel plate, in addition to zinc protection, the organic coating on the zinc layer plays the role of covering isolation, can prevent rust steel plate, service life is longer than galvanized steel plate, according to the introduction of coated steel plate service life is 50% longer than galvanized steel plate.

Color coated steel plate is widely used, because it has no pollution, excellent weather resistance, corrosion resistance, high processing and other characteristics, so color coated steel plate is widely used in construction, home appliances, transportation, packaging, mechanical processing, interior decoration, medical, automobile industry and other industries.
