The lifespan of a prepainted corrugated roofing sheet depends on the environment and coating quality. Our standard PPGI sheets, with a high-quality paint system (PVDF or HDP) and sufficient zinc coating, typically offer a service life of 15-25 years, even in coastal or industrial areas with higher corrosion risk, making them an excellent choice for long life color coated steel roof projects.
Yes, absolutely. We offer a wide range of standard RAL colors for our PPGI roof panels. Custom color matching is also available for larger orders. This flexibility is a key reason our materials are specified for diverse custom color PPGI sheet for building applications worldwide.
For warehouses in rainy or humid climates, we recommend a thicker zinc coating (minimum Z180 or 180 g/m²) combined with a durable paint system like PVDF. A steeper roof profile for better water drainage is also advised. This specification ensures optimal protection against corrosion resistant PPGI for industrial roofing in challenging weather conditions.
We use professional export packing. Sheets are stacked neatly, covered with waterproof plastic film, and securely strapped to wooden pallets or reinforced with angle irons. This method is standard for export packing for PPGI steel coils and sheets and has proven effective in protecting goods during long-haul sea transport to destinations across Africa, South America, and Southeast Asia.
