PPGL Roofing Sheet Manufacturer
Premium Prepainted Galvalume (Aluzinc) roofing sheets. We manufacture the AZ150 PPGL Coil substrate ourselves to ensure 25-year durability, lower cost, and faster delivery.
The Science of PPGL Durability
PPGL (Prepainted Galvalume) outperforms standard galvanized steel (PPGI) thanks to its unique 55% Aluminum-Zinc alloy coating.
- Aluminum (55%): Creates a stable barrier layer that resists atmospheric corrosion and heat.
- Zinc (43.4%): Provides sacrificial protection to heal scratches and cut edges.
This combination allows our AZ150 PPGL sheets to offer a lifespan of 20-25 years, making them ideal for severe environments like coastal areas or chemical plants.

PPGL vs. PPGI: The Ultimate Comparison
If your project is near the sea or in a high-temperature zone, upgrading to PPGL is the smartest investment.
- Lifespan: 8 - 12 Years
- Salt Spray Resistance: Average
- Heat Reflection: Low (Absorbs heat)
- Price: Economical
- Best For: Inland, dry areas, temporary buildings.
- Lifespan: 20 - 25 Years (3-6x longer)
- Salt Spray Resistance: Excellent (Coastal ready)
- Heat Reflection: High (Lowers temp by 5°C)
- Price: Moderate (~10% higher than GI)
- Best For: Coastal, industrial, tropical roofs.
Why Our PPGL Roofing sheet is Cheaper & Better?
Most roofing suppliers are just traders or rolling factories. Everesteel is an integrated manufacturer controlling the process from the raw steel coil to the final roofing sheet.
Quality starts from the substrate. We produce the PPGL Coil in-house, ensuring the AZ coating (AZ30-AZ150) and paint thickness meet international standards.
By eliminating the coil trading intermediary, we save 10-15% on raw material costs, passing these savings directly to you.
Need a special color or width? Since we make the coils, we can customize the exact specs you need before roll forming, reducing waste and lead time.
