Color-coated coil is 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 is baked and cured. It is named after the colored steel coils coated with various colors of organic coatings, referred to as color-coated coils.
PPGI is the abbreviation of Pre-Painted Galvanized, that is, pre-painted galvanized steel. Usually refers to PPGI Coil (color-coated galvanized coil), PPGI Sheet (color-coated galvanized sheet) and other steel products. It is based on galvanized coils and then covered with color coatings to give the product more Color, and this rich and beautiful surface makes it more versatile in use.
PPGL is the abbreviation of Pre-Painted Galvalume, which is covered with a layer of color coating on the basis of galvalume coils.

Features of color coated roll 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 tank to make a layer of zinc adhere to the surface. This galvanized sheet has good paint adhesion and weldability.
Hot-dip galvanized substrate:
The product is plated with 55% AL-Zn, has excellent corrosion resistance, and its service life is more than four times that of ordinary galvanized steel sheets. It is the replacement product of galvanized sheet.
Features:
(1) It has good durability, and its anti-corrosion ability has a longer service life than galvanized steel sheets;
(2) It has good heat resistance and is less likely to change color at high temperatures than galvanized steel sheets;
(3) Has good heat reflectivity;
(4) It has processing performance and spraying performance similar to that of galvanized steel sheet;
(5) It has good welding performance.
(6) Good performance-price ratio, durable performance and very competitive price. Therefore, whether it is architectural designers, engineers or manufacturers, galvanized steel sheets have been widely used in industrial buildings, steel structures and civil facilities, such as garage doors, gutters and roofs.
