Stone Grain PVDF Coated Aluminum Coil, Marble Texture Pre-Painted Aluminum Roll for Outdoor Building Facade, Aluminum Cladding Panel And Exterior Wall Decoration

Core Advantages

1. Realistic Stone Texture

   The surface presents natural marble or granite texture, which can replace natural stone for building facade decoration, creating a high-end and stable visual effect.

2. PVDF Fluorocarbon Coating System

   Equipped with PVDF fluorocarbon coating, it has excellent weather resistance, UV resistance, salt spray resistance and anti-fading performance, suitable for long-term outdoor use.

3. Lightweight and Safe

   Compared with natural stone, aluminum coil is lighter and easier to transport, process and install. It reduces building load and is more suitable for high-rise buildings and large facade projects.

4. Strong Coating Adhesion

   Through complete surface pretreatment and high-temperature curing process, the stone grain coating has strong adhesion and is not easy to peel off during cutting, bending and forming.

5. Durable Outdoor Performance

   PVDF fluorocarbon coating can resist sunlight, rain, salt spray and temperature changes, helping to maintain stable color and texture for a long time.

6. Customizable Stone Patterns

   Available in various stone grain designs such as marble, granite, travertine and slate. Custom patterns and colors can also be provided according to project requirements.

7. Modern Building Facade Effect

   It is suitable for high-end commercial buildings, hotels, exhibition halls, airports, shopping malls and public buildings, giving the facade a stable, luxurious and modern appearance.

8. Easy Processing and Installation

   The aluminum coil can be processed into various panel shapes, including flat panels, curved panels, special-shaped panels and large-area wall panels.

Production Process

Aluminum ingot melting → Casting → Hot rolling → Cold rolling → Annealing → Base coil slitting → Degreasing and water washing → Chemical passivation → PVDF primer coating → High temperature curing → Stone grain pattern coating or transfer → PVDF top finish coating → Secondary curing → Cooling → Protective film laminating → Finished coil rewinding → Inspection → Export packaging

The production process ensures uniform coating thickness, clear stone texture, consistent color and strong adhesion.

Export Packaging Standard

Each stone grain PVDF coated aluminum coil is wrapped with moisture-proof PE film and thick kraft paper to protect the patterned surface from scratches, dust and moisture. The coil is fixed on a fumigated wooden pallet with steel strapping to prevent movement and deformation during sea transportation. Clear shipping labels can include alloy grade, thickness, width, pattern name, color code, net weight and batch number. Fumigation certificate can be provided for overseas customs clearance.

Inspection & After-sales Service

Before shipment, the product undergoes strict inspection, including stone pattern clarity, color difference comparison, coating thickness test, cross-cut adhesion test, weather resistance test, surface defect inspection and dimension verification. Complete documents such as MTC material test certificate, coating performance report, RoHS certificate, MSDS, commercial invoice and packing list can be provided. If any quality problem is found within 7 working days after receiving goods, please provide clear photos and video evidence. The technical team will respond within 24 hours and provide solutions such as re-production, supplementary shipment or reasonable compensation.

FAQ

Q1: Can stone grain aluminum coil replace natural stone?

A: Yes, it can simulate the appearance of natural stone while being lighter, easier to process and more cost-effective for large-area facade projects.

Q2: Is stone grain PVDF coated aluminum coil suitable for outdoor use?

A: Yes, PVDF fluorocarbon coating provides good weather resistance, making it suitable for long-term outdoor building facade applications.

Q3: What stone patterns can be produced?

A: Common patterns include marble, granite, travertine, slate and other custom stone grain designs.

Q4: Can the pattern be kept consistent in large-area projects?

A: Yes, the continuous coil production process helps ensure relatively consistent pattern and color performance across large batches.

Q5: Does stone grain aluminum coil require special maintenance?

A: It only requires regular cleaning. The PVDF coating has good stain resistance and weather resistance, making it suitable for long-term building exterior use.
