Color-coated coil substrate
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.
PPGI coil or PPGL coil Features:
(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.
