Industrial Grade 41mm PPGL Roof Sheets Featuring High Solar Reflectivity

Industrial Grade 41mm PPGL Roof Sheets Featuring High Solar Reflectivity

Engineered for superior performance in industrial construction, our Pre-Engineered PPGL Steel Roofing Sheets deliver exceptional durability with 41mm corrugated profiles optimized for maximum structural integrity. Featuring a robust 120g/m² coating (PE/SMP/HDP options) over an AZ100-AZ150 galvalume base, these sheets exceed 1,000 hours in ASTM B117 salt spray tests to resist corrosion in coastal/industrial environments. The integrated anti-fingerprint nano-layer maintains aesthetic quality in polluted areas, while Class 1 color retention (ISO 12944) ensures long-term visual appeal. Certified for Class F wind uplift (ASTM D3161) and IBC 2018 seismic compliance, these sheets support spans up to 3.5m unsupported. Ideal for warehouses, factories, and agricultural buildings, they combine heavy-duty protection with industry-leading 25-year performance warranties.
