Characteristics of color coated coil steel plate

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

Hot dip galvanized substrate: immerse the steel sheet into the molten zinc bath to make its surface adhere with a layer of zinc. This galvanized plate has good coating adhesion and weldability.

Hot dip aluminum zinc substrate:

The 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 plate. It is a new generation of galvanized sheet.

Product features:

(1) It has good durability, corrosion resistance and longer service life compared with galvanized steel plate;

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

(3) Good thermal reflection;

(4) It has similar processability and spraying performance with galvanized steel plate;

(5) Good welding performance.

(6) It has good performance price ratio, durable performance and 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.

Editing and broadcasting of coating types of color coated rolls

Polyester (PE)

Good adhesion, rich colors, wide range in formability and outdoor durability, medium chemical resistance and low cost.

Silicon modified polyester

That is (SMP), the hardness, wear resistance and heat resistance of the coating film are good, as well as good external durability and pulverization resistance, gloss retention, general flexibility and medium cost.

High durability polyester

Namely (HDP), excellent color retention and UV resistance, excellent outdoor durability and pulverization resistance, good film adhesion, rich colors and excellent cost performance.

Polyvinylidene fluoride

Namely (PVDF), excellent color retention and UV resistance, excellent outdoor durability and pulverization resistance, excellent solvent resistance, good formability, dirt resistance, limited color and high cost.
