Hot dipped Steel Zinc Coated Galvanized Steel Coil Corrugated Sheet

Short Description:

Color-coated coils are based on hot-dip galvanized sheet, hot-dip galvanized sheet, electro-galvanized sheet, etc. After surface pretreatment (chemical degreasing and chemical conversion treatment), one or several layers of organic coatings are applied on the surface, and then A product that has been cured by baking.

The color-coated steel strip using hot-dip galvanized steel strip as the base material is protected by the zinc layer, and the organic coating on the zinc layer plays a covering and protective role to prevent the steel strip from rusting, and the service life is longer than that of the galvanized strip, about 1.5 times.

Color Coating Roll Application

Color-coated coils are light, beautiful and have good anti-corrosion properties, and can be directly processed. The colors are generally divided into gray-white, sea-blue and brick red. They are mainly used in advertising, construction, household appliances, electrical appliances, furniture and transportation. Industry.


Hot dip galvanized substrate

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

Hot-dip Al-Zn substrate

The hot-dip galvanized steel sheet (55% Al-Zn) is used as the new coating substrate, and the content of aluminum and zinc is usually 150g/㎡ (double-sided). The corrosion resistance of hot-dip galvanized sheet is 2-5 times that of hot-dip galvanized sheet. Continuous or intermittent use at temperatures up to 490°C will not severely oxidize or produce scale. The ability to reflect heat and light is 2 times that of hot-dip galvanized steel, and the reflectivity is greater than 0.75, which is an ideal building material for energy saving.

Electro-galvanized substrate

The electro-galvanized sheet is used as the substrate, and the product obtained by coating organic paint and baking is electro-galvanized color-coated sheet. Because the zinc layer of the electro-galvanized sheet is thin, the zinc content is usually 20/20g/m2, so this product is not suitable for use. Make walls, roofs, etc. outdoors. But because of its beautiful appearance and excellent processing performance, it can be mainly used in home appliances, audio, steel furniture, interior decoration, etc.


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

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

Hot-dip Al-Zn substrate:

The product is plated with 55% AL-Zn, has excellent anti-corrosion performance, and its service life is more than four times that of ordinary galvanized steel. It is a replacement product of galvanized sheet.


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

(2) It has good heat resistance and is less prone to discoloration at high temperature than galvanized steel;

(3) It has good thermal reflectivity;

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

(5) It has good welding performance.

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