prepainted galvalume steel coil roofing
,aluminum-zinc coated steel wall panels
,color coated PPGI coils
PPGL steel coil (Prepainted Galvalume Steel Coil) is a high-performance coated steel product manufactured by applying organic coatings on galvalume steel substrate (55% aluminum, 43.4% zinc, 1.6% silicon).
Compared to PPGI, PPGL offers significantly enhanced corrosion resistance, heat reflectivity, and longer service life, especially in harsh environments such as coastal areas, industrial zones, and high-temperature regions.
With advanced continuous coating technology, our PPGL coils feature uniform paint thickness, excellent adhesion, and stable color performance. It is widely recognized as the preferred material for high-end construction and long-life roofing systems.

PPGL stands for Prepainted Galvalume Steel Coil, which is a color-coated steel product based on aluminum-zinc alloy coated steel.
PPGL uses an aluminum-zinc coating, providing better corrosion resistance and longer lifespan, while PPGI uses zinc coating and is more economical.
Yes, PPGL is highly recommended for coastal and high humidity environments due to its superior anti-corrosion properties.
Depending on coating type:
- SMP: 10–15 years
- HDP: 15–20 years
- PVDF: 20–25 years
Yes, PPGL is widely used in roofing due to its durability, heat resistance, and color stability.
Yes, we support:
- Custom thickness & width
- Color matching (RAL)
- Coating thickness
- Special surface finishes
