PPGI stands for Prepainted Galvanized Iron. It is a coated steel product made by painting galvanized steel, offering both corrosion protection and decorative appearance.

PPGI uses galvanized steel (zinc coating), while PPGL uses galvalume steel (aluminum-zinc coating). PPGL generally provides better corrosion resistance, while PPGI is more cost-effective.

The lifespan depends on the coating type and environment:
