PPAL Coil Sheet Benefit and Application
PPAL coil sheet is a durable and versatile construction and industrial material with excellent physical and mechanical properties, environmental friendliness, and aesthetics, It is widely used in construction, transportation, home appliances, and many other industries, and is the ideal metal material solution for applications with high demands on appearance and performance.


Benefit
- Lightweight: Aluminum has a density of 2.7g/cm³, which is only 1/3 that of steel.
- High corrosion resistance: Due to the use of an aluminum base material, PPAL has excellent corrosion resistance due to the natural oxidation of the aluminum to form an Al₂O₃ protective film.
- Weatherability: PPAL’s coating provides strong resistance to UV rays, weathering, and other weathering.
- Decorative: PPAL is available in mirror, matte, brushed metal, and other surface effects, and supports customized patterns (wood grain, brick pattern, flower, marble, etc.). Support customized patterns (wood grain, brick grain, flower, marble, etc.).
- Formability: Excellent ductility (elongation ≥10%), suitable for stamping and bending.
- Fire resistance: Aluminum sheet has a high melting point, which can provide a certain degree of fire resistance.
- Environmentally friendly: 100% recyclable, 95% lower energy consumption than steel.

3. Quality Certificates and Standards
Our factory has passed ISO 9001 and ISO 14001 certificates, and we also accept third-party organizations such as BV and SGS to inspect our factory.
PPAL Coil Sheet Production Process



Aluminum substrate preparation
- Cold rolled aluminum coil → degreasing and cleaning → chemical conversion.
Coating process
- Roller Coating: Synchronized coating on both sides (precision ±1μm).
- Curing: Segmented oven (PE: 200-220°C; PVDF: 230-250°C).
Post-treatment
- Coated with protective film → splitting/winding → quality control and packaging.
Comparison Between PPAL and PPGI
PPAL and PPGI are two kinds of popular pre-painted metal material, PP means pre-painted, AL means aluminum, and GI means galvanized, both of them use different metal materials as the substrate through the color-coated metal.
Parameters | PPAL (Pre-painted Aluminum) | PPGI (Pre-painted Galvanized Steel) |
Substrate | Aluminum alloy | Galvanized steel sheet |
Density | 2.7 g/cm³ | 7.85 g/cm³ |
Corrosion resistance | Very good | Excellent |
Cost | High | Low |
