What is PPGL Sheet?
PPGL (Prepainted Galvalume Steel Sheet) is a high-performance material that combines the superior corrosion resistance of galvalume coating with the aesthetic appeal of premium color coating.
Unlike traditional PPGI (galvanized base), PPGL uses Galvalume base steel (55% aluminum, 43.5% zinc, 1.5% silicon), offering:
3-5 times better corrosion resistance than galvanized steel
Superior heat reflectivity for energy-saving roofing
Excellent cut-edge protection with aluminum barrier effect
Longer service life up to 20-25 years in harsh environments
This makes PPGL the preferred choice for roofing, wall cladding, and applications in coastal or high-humidity regions.
