PPGL Coil Manufacturer
(Prepainted Aluzinc / Galvalume)
Everesteel is a premier manufacturer of Prepainted Aluzinc Steel Coils (PPGL). Featuring a 55% Aluminum-Zinc alloy substrate, our coils offer 3-6 times better corrosion resistance than standard steel. Ideal for manufacturing durable PPGL Roofing Sheets in coastal areas.
What is PPGL Sheet Full Form?
The PPGL sheet full form is Pre-Painted Galvalume Steel. In some regions, it is also known as Prepainted Aluzinc.
Unlike standard PPGI, PPGL uses a substrate of Hot Dipped Galvalume (GL) consisting of 55% Aluminum, 43.4% Zinc, and 1.6% Silicon. This unique composition provides self-healing protection.

Factory-direct prepainted aluzinc coils for roofing, appliances, and construction.
PPGI vs PPGL: Which One to Choose?
Choosing between Galvalume and Galvanized depends on your environment.
- Substrate: Zinc Coated
- Cost: Economical ($$)
- Edge Protection: Excellent
- Lifespan: 10-15 Years
- Substrate: 55% Al-Zn Alloy
- Cost: Premium ($$$)
- Corrosion Resistance: Superior (3-6x better)
- Lifespan: 25+ Years
Yield Comparison: Get More Meters Per Ton
Because Aluminum (in PPGL) is lighter than Zinc (in PPGI), 1 ton of PPGL yields more square meters. This makes your actual "Cost Per Meter" very competitive.
| Thickness | Width | PPGI Length / Ton | PPGL Length / Ton | Extra |
|---|---|---|---|---|
| 0.40 mm | 1000 mm | 318 Meters | 329 Meters | +3.5% |
| 0.50 mm | 1000 mm | 254 Meters | 263 Meters | +3.5% |

Empowering Diverse Industries with PPGL
Whether you are fabricating corrosion-resistant roofing for coastal villas or stamping precision parts for home appliances, our PPGL adapts to your needs.
Roofing & Cladding
Provides an attractive, colorful finish that protects the Galvalume substrate from harsh weather in residential and industrial buildings.
Wall Panels
Used for exterior and interior panels. Enhances structural aesthetics while acting as a barrier against environmental elements.
Garage Doors
Ensures garage doors remain rust-free and functional. PPGL offers excellent resistance to scratching and wear.
Home Appliances
Ideal for refrigerator doors, washing machines, and ovens. The coating withstands deep drawing without peeling.
Expert Tips for Cost & Quality
- Thinning: Reduced AC panel from 0.6mm to 0.5mm via CAE simulation. Saved 4.2 RMB/unit.
- Substitution: Replaced PVDF with High-Weatherability PE for washer tops. Cost down 32%.
- Integrated Design: One-piece stamping for microwave front/side panels. Processing fee down 15%.
- Orange Peel: Caused by poor leveling. Fix: Adjust paint viscosity to 90-110KU.
- Color Difference: Require Delta E ≤ 1.0. Use same batch paint for one project.
- Blistering: Substrate grease residue. Ensure surface tension ≥38mN/m after degreasing.

Price Secret: Cost Per Meter
Is PPGL coil price higher? Yes, per ton.
Is it expensive? No, per meter.
Because Aluminum is lighter than Zinc, 1 ton of PPGL is longer than 1 ton of PPGI (at same thickness). You get more square meters for your money!
