0.6mm 3004 PVDF Coated Aluminum Sheet
0.6mm 3004 PVDF coated aluminum sheet is a lightweight, corrosion‑resistant, and color-stable panel material widely used in building facades, roofing, ceilings, and industrial enclosures. The combination of 3004 aluminum alloy and PVDF (polyvinylidene fluoride) coating delivers excellent outdoor durability, formability, and long-lasting color retention.
3004 is an Al-Mn-Mg alloy (manganese and magnesium as the main alloying elements). It offers higher strength than 3003 while maintaining good ductility and corrosion resistance. When combined with a PVDF paint system, the surface gains superior weatherability and UV resistance, ideal for architectural use.
Typical Chemical Composition of 3004 Aluminum (wt%)

Why Choose 0.6mm 3004 PVDF Coated Sheet?
Balance of Strength and Formability
- 3004 alloy provides higher strength than 1xxx or 3xxx pure aluminum grades while remaining easy to bend, cut, and profile.
- 0.6mm thickness is rigid enough for many façade, cladding, and roofing systems, yet still light and cost-effective for large-area coverage.
Lightweight and Easy Handling
| Parameter | Approximate Value for 0.6mm Sheet |
|---|---|
| Areal Density | ~1.64 kg/m² |
| Panel Size Example | 1000 mm × 3000 mm |
| Weight of Example Panel | ~4.9 kg |
Handling, transportation, and installation are easier and faster than with many traditional materials such as steel or solid composite boards.
Superior Weather and UV Resistance
- PVDF coating offers long service life in harsh climates: coastal, industrial, and high-UV regions.
- Stable color and gloss help maintain building appearance for decades, reducing repainting and maintenance costs.
Design Flexibility
- Wide color range: solid, metallic, pearlescent, and custom RAL/ Pantone colors.
- Compatible with typical fabrication methods:
- Shearing and slitting
- Press braking and roll forming
- Punching and notching
- Suitable for flat panels, corrugated sheets, sandwich panels, and cassette systems.

Processing and Fabrication Notes
- Suitable for most common sheet-metal processes: cutting, bending, roll forming, and drilling.
- Minimum bending radius should respect coated sheet guidelines to avoid micro-cracking of the paint film; radius depends on die design and bending direction.
- Pre-punched and pre-formed panels should be handled with soft pads to protect the PVDF surface and prevent scratching.
- Edge protection and proper sealing are recommended in aggressive environments, such as marine or heavily industrial locations.
Storage, Handling, and Installation
| Aspect | Recommendation |
|---|---|
| Storage environment | Dry, clean, covered, away from direct moisture |
| Stacking | Use spacers; avoid hard contact between coils |
| Protective film | Remove after installation or within recommended time to avoid residue |
| Cutting | Use sharp tools; blow off chips to protect finish |
| Fasteners | Corrosion-compatible screws and rivets (e.g. stainless steel or coated fasteners) |
