What is PPGL Roofing Sheet?
PPGL roofing sheet is a prepainted galvalume steel product composed of a cold-rolled steel substrate coated with an aluminum-zinc alloy layer (typically 55% aluminum, 43.4% zinc, and 1.6% silicon by weight), followed by a chemical treatment and a baked-on organic paint coating. This multi-layer construction delivers outstanding anti-corrosion properties alongside superior heat reflectivity, making it a preferred roofing material for environments exposed to humidity, UV radiation, and extreme temperature fluctuations. The paint layer thickness typically ranges from 15 to 25 microns on the top surface, ensuring long-term color retention and weather resistance.
PPGL Roofing Sheet Manufacturing Process
The manufacturing process of PPGL roofing sheets begins with premium cold-rolled steel coils that undergo hot-dip galvalume coating in a continuous galvanizing line, achieving a coating mass of AZ50 to AZ150 (50–150 g/m²). The galvalume-coated substrate then passes through a chemical passivation treatment to enhance paint adhesion. Subsequently, primer and topcoat layers are applied via precision roll-coating equipment and cured in high-temperature ovens at approximately 230°C to 260°C peak metal temperature (PMT), ensuring superior coating hardness, flexibility, and impact resistance compliant with ASTM A755 and EN 10169 standards.
