Galvanized steel coils
Galvanized steel coils is a metal material that is coated with a layer of zinc on the surface of steel through hot-dip galvanizing process. This layer of zinc can effectively prevent rust and corrosion of steel, while providing a certain degree of wear resistance.

Galvanized steel coils is a metal material that is coated with a layer of zinc on the surface of steel through hot-dip galvanizing process. This layer of zinc can effectively prevent rust and corrosion of steel, while providing a certain degree of wear resistance. The main uses include construction, home appliances, automobiles, containers and transportation facilities, home appliances and container manufacturing, agricultural facilities and other fields. Due to its anti-corrosion performance and forming ability, it provides reliable material guarantee for various products and facilities.
Galvanized steel coils features:
Corrosion resistance: There is a zinc layer on the surface, which can effectively prevent the steel coil material from corroding when it comes into contact with the external environment. This is because zinc forms a protective film in the air, which can prevent oxygen and water from further contacting the steel surface.
Durability: Due to the anti-corrosion properties of the zinc layer, it has a long service life and is especially suitable for harsh environmental conditions such as moisture, salt spray, etc.
Formability: The surface zinc layer is uniform and can be easily formed by various mechanical processing methods, such as stamping, bending, etc., to meet the manufacturing needs of different products.
Aesthetics: The surface is smooth and the color is uniform, which can provide a good appearance effect and is suitable for applications that require appearance decoration.

PPGI coils / Pre-Painted Galvanized coils
PPGI coils is a metal sheet made by pre-treating the surface of hot-dip galvanized steel sheet or hot-dip aluminum-zinc steel sheet, coating it with one or more layers of organic coating, and curing it by baking. It combines the anti-corrosion performance of galvanized steel sheet with the aesthetics and functionality of color coated steel sheet. It is often used in the production of roofs, walls, doors and corrugated sheets for the construction of steel structure factories, warehouses, freezers and other industrial and commercial buildings, and is used for exterior wall decoration and roof production.
