Roofing Solutions FAQ

Q: PPGI vs. PPGL Roofing — Which one should I choose?

A: PPGI (Galvanized) is cost-effective for general use. PPGL (Galvalume) contains 55% aluminum, offering superior heat reflectivity and higher corrosion resistance, perfect for coastal or hot industrial zones.

Q: How do you guarantee the paint quality?

A: We use high-grade coatings from reputable brands. Every batch undergoes T-Bend, Pencil Hardness, and Salt Spray tests to ensure the coating doesn't peel or fade prematurely.
