Key Takeaways for Buyers

1. Coating Choice Determines Lifespan

PE (Polyester) is cost-effective for indoor use and standard roofing. PVDF (Polyvinylidene Fluoride) offers superior UV resistance for coastal and high-exposure outdoor environments. HDP (High-Durability Polyester) is the middle ground — better than PE, more affordable than PVDF.

2. Thickness and Width Flexibility

Calibre estándar: de 0,12 mm a 1,20 mm. Ancho estándar: hasta 1.250 mm. Se ofrecen opciones de corte longitudinal y corte a medida para pedidos OEM.

3. Base Metal Matters

PPGI uses a galvanized (zinc-coated) steel substrate. PPGL uses a galvalume (aluminum-zinc alloy) substrate, offering 2–4× better corrosion resistance than standard galvanized.

4. RAL Color Matching

Full RAL color range available. Custom color matching supported for volume orders. Minimum order quantity for custom colors: consult with our sales team.

5. Embalaje listo para la exportación

Standard sea-worthy packaging with edge protectors, waterproof paper, and steel strapping. Custom labeling and palletizing available for distributor orders.
