Color coated roll

Color-coated rolls are based on hot-dip galvanized sheet, hot-dip aluminized zinc sheet, electro-galvanized sheet, etc. as the substrate. After surface pretreatment (chemical degreasing and chemical conversion treatment), one or several layers of organic coatings are applied to the surface, and then After baking and curing, the product is named after the colored steel coil coated with various colors of organic coatings, referred to as color-coated rolls.

In addition to the protection of the zinc layer, the organic coating on the zinc layer covers and protects the steel strip from rusting, and the service life is longer than that of the galvanized strip, about 1.5 times.

Use of color coated rolls

Color coated rolls have light weight, beautiful appearance and good anti-corrosion properties, and can be directly processed. The colors are generally divided into gray, sea blue, and brick red. They are mainly used in advertising, construction, home appliance industry, electrical appliance industry, furniture industry and transportation industry..

The paint used in the color coating coil chooses the appropriate resin according to the different use environment, such as polyester silicon modified polyester, polyvinyl chloride plastic sol, polyvinylidene chloride, etc. Users can choose according to the use.

Color Coated Coil Substrate Characteristics

Electro-galvanized substrate: the coating is thinner and the corrosion resistance is not as good as that of hot-dip galvanized substrate;

Hot-dip galvanized substrate: It is to immerse a thin steel plate in a molten zinc bath to make a layer of zinc adhere to its surface. This galvanized plate has good adhesion and weldability of the coating.

Hot dip aluminized zinc substrate:

This product is plated with 55% AL-Zn and has excellent corrosion resistance. Its service life is more than four times that of ordinary galvanized steel sheet. It is a replacement product for galvanized sheet.

Product Features:

(1) It has good durability and corrosion resistance, which is longer than that of galvanized steel sheet;

(2) It has good heat resistance and is less likely to change color at high temperature than galvanized steel sheet;

(3) It has good heat reflectivity;

(4) It has similar processing performance and spraying performance to galvanized steel sheet;

(5) It has good welding performance.

(6) It has a good performance-price ratio, durable performance and very competitive price. Therefore, whether architectural designers, engineers or manufacturers have been widely used in industrial buildings, steel structures and civil facilities, such as garage doors, gutters and roofs.
