High Durable 2.35MM Thickness Coral Stone Grain Color Coated Aluminum Coil
Stone-pattern color-coated aluminum coil is a decorative material that replicates the texture of
natural stone through special coating or embossing processes on aluminum alloy coils. Comb
-ining the lightweight and corrosion-resistant properties of aluminum with the high-end aesthetics
of stone, it is widely used in architecture, interior design, and industrial applications.
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 Appeal
Mimics natural coral/stone textures through embossing or coating techniques, offering a balance
of organic aesthetics and modern industrial design.
✅ Lightweight & Durable
Aluminum’s density (~1/3 of steel) reduces structural load while maintaining strength (e.g., 5052 for
heavy-duty use).
✅ Corrosion Resistance
Natural oxide layer + protective coatings (e.g., PVDF or polyester) enhance UV, acid rain, and salt
spray resistance (service life: 20+ years).
✅ Formability
Easily fabricated into curved panels, perforated designs, or custom shapes without coating damage.
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 |
Primary Applications
① Architecture & Cladding
Facades/Curtain Walls: Replaces stone to reduce building weight (ideal for high-rises).
Interiors: Elevator cladding, feature walls, and ceilings.
② Transportation
Ship interiors, train/aircraft cabin panels (lightweight + fire-retardant options available).
③ Furniture & Appliances
Luxury cabinets, refrigerator panels, and decorative trims.
④ Outdoor Structures
Signage, pergolas, and landscape elements (durable in extreme weather).
