Prepainted galvanized steel
Prepainted galvanized steel coil is (PPGI)a type of steel product that is first galvanized with a zinc coating and then coated with a layer of organic paint through a continuous coating process.
The zinc layer provides corrosion resistance, while the paint layer enhances both protection and appearance. It is widely used across construction, home appliances, and industrial manufacturing due to its durability and versatility.
Advantages:
- Excellent corrosion resistance due to zinc coating and protective paint layer.
- Long service life with strong resistance to weather and environmental exposure.
- Wide range of colors and surface finishes for flexible design options.
- Low maintenance and cost-effective compared to many alternative materials.
Prepainted galvalume steel
Prepainted Galvalume steel coil (PPGL) is a high-quality steel product made by coating a steel substrate with an aluminum-zinc alloy (typically 55% aluminum, 43.5% zinc, and 1.5% silicon), followed by a layer of organic paint through a continuous coil coating process. Compared with traditional galvanized steel, PPGL offers enhanced corrosion resistance and better heat reflectivity, making it suitable for both structural and decorative applications.
Advantages:
- Superior corrosion resistance, especially in harsh or coastal environments.
- Excellent heat reflectivity, helping reduce surface temperature and energy consumption.
- Long service life with strong resistance to weathering and oxidation.
- Good formability and aesthetic versatility with various colors and finishes.
