DESCRIPTION

DETAILS

In the continuous unit to cold-rolled strip, galvanized strip (galvanized and hot-dip galvanized) as the substrate, after the surface pretreatment (degreasing and chemical treatment), with roll coating method, coated with one or more layers of liquid Paint, after baking and cooling the resulting plate is coated steel. Domestic back (bottom) paint and surface (front) paint coating, the general domestic one layer of paint, paint two layers, foreign business paint back paint are two layers. As the coating can have a variety of colors, the customary to the coated steel plate called color coated steel.

Color coated substrate type

Cold-rolled substrate color coated steel

The color plates produced from cold-rolled substrates have a smooth, beautiful appearance and have the processing properties of cold-rolled plates; however, any small scratches on the surface coating expose the cold-rolled substrates to the air, causing the dew Generate red rust. Therefore, these products can only be used for less demanding temporary isolation measures and for indoor timber.

Hot dip galvanized color coated steel

The organic coating coated on hot-dip galvanized steel products obtained is hot galvanized color coated plate. In addition to the hot-dip galvanized color coated with zinc protection, the organic coating on the surface also played a protective isolation to prevent rust, the service life of hot-dip galvanized sheet longer. Hot dip galvanized substrate zinc content is generally 180g / m2 (double), building exterior hot dip galvanized substrate galvanized up to 275g / m2.

Hot-dip galvanized color coated plate

Depending on requirements, hot-dip aluminized steel sheets can also be used as color coated substrates (55% AI-Zn and 5% AI-Zn).

Galvanized color coated plate

Galvanized sheet as a substrate, coated with organic paint baked product is galvanized color coated steel sheet, galvanized sheet due to the zinc layer is thin, usually zinc content of 20 / 20g / m2, so the product is not suitable for use In the outdoor production walls, roofs and so on. But because of its beautiful appearance and excellent processing properties, it is mainly used for home appliances, audio, steel furniture, interior decoration, etc.
