PPGI & PPGL (prepainted galvanized steel & prepainted galvalume steel) also known as pre-coated steel or color coated steel coil,It is a product made of hot-dip galvanized steel sheet, hot-dip galvalume steel sheet, electro galvanized steel sheet, etc. After surface pretreatment, one or several layers of organic coating are applied on the surface, and then baked and solidified. The color coated steel coil is light in weight, beautiful in appearance, and has good anti-corrosion performance, and can be directly processed.

S550GD Color-Coated Coil is a double-sided coated coil made from high-strength galvanized steel (yield strength ≥550 MPa) as the substrate, featuring excellent weather resistance achieved through pre-applied polyester/PVDF coatings. Combining ultra-high strength with decorative and protective functions, it is particularly suitable for high-load-bearing applications such as steel structure building roofs and soundproof barriers. It offers a corrosion resistance lifespan of up to 20 years and supports custom colors and embossed patterns.

1. Color Coated steel Coil is coated with organic layer, which provides higher anti-corrosion property and a longer lifespan than that of galvanized steel sheets.
2. The base metals for Color Coated Steel Coil consist of cold rolled, HDG electro-galvanized and hot-DIP alu-zinc coated steel. The finish coats of Color Coated Steel Coil can be classified into groups as follows: Polyester, silicon modified polyesters, polyvinylidene fluoride, high-durability polyester, etc.
3. The production process has evolved from one-coating-and-one-baking to double-coating-and-double-baking, and even three-coating-and-three-baking.
4. The color of the Color Coated Steel Coil has a very wide selection, like orange, cream-colored, dark sky blue, sea blue, bright red, brick red, ivory white, porcelain blue, etc.
5. The Color Coated Steel Coil can also be classified into groups by their surface textures, namely regular prepainted sheets, embossed sheets and printed sheets.

DX53D color-coated coiled sheet is manufactured using deep-drawing grade galvanized coiled sheet (DX53D+Z) as the substrate, which is then surface-treated and coated with a high-performance polyester/fluorocarbon coating. It combines exceptional formability (capable of 180° bending) with decorative appeal, offering a weather resistance lifespan of 10–15 years. Ideal for high-end appliance panels, building facades, and other applications requiring complex forming and aesthetic appeal, it offers a variety of color and texture options.
