Scratch Resistance 25 / 5UM PVDF Coating Stone Pattern Aluminum Coil
Stone Pattern Aluminum Coil is a premium decorative material that replicates the natural texture
and appearance of stone through advanced surface treatment technology. Combining the luxurious
aesthetics of stone with the practical benefits of metal, it offers an innovative solution for modern
architectural decoration.
Common-used Aluminum Alloy
| Alloy Series | Common Grades | Key Properties | Typical Use Cases |
| 1000 Series | 1050, 1060 | High purity, excellent corrosion resistance | Indoor decorative panels, ceilings |
| 3000 Series | 3003, 3005 | Good strength + formability, Mn-enhanced | Facades, column cladding |
| 5000 Series | 5052, 5754 | High Mg content, marine-grade durability | Coastal buildings, high-humidity interiors |
Performance Advantages
✅ Aesthetic Versatility
Realistic granite/marble/slate replication via 3D digital printing + nano-embossing
Customizable patterns (vein density, gloss levels 10-90°)
✅ Superior Durability
1) Weather Resistance:
4,000h salt spray (ASTM B117)
ΔE<3 after 10,000h QUV (ASTM G154)
2) Physical Properties:
Scratch resistance (3H pencil hardness)
Fire Rating A2-s1,d0 (EN 13501-1)
✅ Economic & Practical Benefits
1/5 the weight of natural stone (2.7g/cm³)
60% lower installation cost vs. stone cladding
No sealing/maintenance required
Comparison with Natural Stone
| Parameter | Stone-Pattern Aluminum | Natural Stone |
| Installation Speed | 3x faster (modular systems) | Slow (mortar-based) |
| Color Consistency | Batch-to-batch control | Natural variation |
| Structural Load | No reinforcement needed | Often requires structural support |
