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.
Our Company
♦ We have implemented standardized processes to enhance work efficiency, reduce confusion,
minimize errors, and boost overall productivity.
♦ A comfortable and well-lit work environment, combined with a reasonably arranged office layout,
fosters a positive work attitude, healthy interpersonal relationships, and sustained team growth
motivation, while enhancing team cohesion and a sense of belonging.
♦ The left 1 is me, we sincerely look forward to the cooperation with your company.
Quality Control
1) We test the bending and hardness property for every batch raw material,
make sure the Alloy Temper can meet customer’s requirement.
2) During the production process, we use online inspection systems to monitor key parameters,
such as coating thickness, uniformity, adhesion.
3) Before delivery, we will select samples to test, including grid testing, impact testing, and bending
testing. For some special products, we will carry out some chemical testing.
4) We have MTC for every batch product, convenient for tracking and confirmation. Test records
are kept by our laboratory staffs.
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 |
