description

Color coated coil is hot galvanized plate, hot galvanized aluminum zinc plate, galvanized plate and other substrates, the surface pretreatment (chemical degreasing and chemical conversion treatment), on the surface coated with a layer or several layers of organic coating, and then after baking curing products. Because coated with a variety of different colors of organic paint color steel coil plate named, referred to as color coated coil.

Color coating roller application
Color coated coil material light weight, beautiful, good corrosion resistance, can be directly processed. Colors are generally classified as off-white, navy blue and brick red. They are mainly used in advertising, construction, household appliances, electrical appliances, furniture and transportation. Industry.

Color coated coil substrate classification and broadcasting

Hot dip galvanized substrate
Hot dip galvanized color coated plate is the product of organic coating on hot dip galvanized steel plate. In addition to the protective effect of zinc, the organic coating on the surface of hot dip galvanized color coated plate also plays a role in insulation and protection, preventing rust, and the service life is longer than that of hot dip galvanized. Galvanized sheet. The zinc content of hot-dip galvanized substrate is generally 180g/m2 (double-sided), and the maximum galvanized amount of hot-dip galvanized substrate for exterior walls of buildings is 275g/m2.

Hot dipped aluminum-zinc substrate
Hot dip galvanized steel sheet (55% Al-Zn) is used as the new coating base material, the content of aluminum and zinc is usually 150g/ m2 (double-sided). The corrosion resistance of hot galvanized sheet is 2-5 times that of hot galvanized sheet. Continuous or intermittent use at temperatures up to 490°C does not result in severe oxidation or scaling. The ability of reflecting heat and light is twice that of hot-dip galvanized steel, and the reflectivity is greater than 0.75. It is an ideal energy-saving building material.

Galvanized zinc substrate
Galvanized sheet as the base material, coated with organic paint, baked products for galvanized color coated plate. Due to the thin zinc layer of galvanized sheet, zinc content is usually 20/20g/m2, so it is not suitable to use this product. Make walls, roofs, etc outdoors. But because of its beautiful appearance, excellent processing performance, can be mainly used in household appliances, acoustics, steel furniture, interior decoration, etc.

Color coated coil substrate features edit and play

Galvanized base material: thin coating, corrosion resistance is not as good as hot dip galvanized base material;
Hot-dip galvanized substrate: A thin sheet of steel dipped in a molten zinc bath to coat the surface with zinc. This galvanized sheet has good coating adhesion and weldability.
Hot dip aluminum zinc substrate: 55% Al-Zn plating, excellent anti-corrosion performance, service life is more than 4 times of ordinary galvanized steel. It is the replacement of galvanized sheet.
Features:
(1) Good durability, corrosion resistance is longer than galvanized steel;
(2) good heat resistance, at high temperature than galvanized steel is not easy to change color;
(3) It has good thermal reflectivity;
(4) similar to galvanized steel plate processing performance and spraying performance;
(5) It has good welding performance.
(6) With good cost performance, durable performance and very competitive price. Therefore, architects, engineers and manufacturers have been widely used in industrial buildings, steel structures and civil facilities, such as garage doors, gutters and rooftops.
