Aluminum Roof Panels For Metro Station Platform Project
Hanchen Metal, a leading manufacturer and exporter of color coated aluminum coil, is proud to announce the successful completion of a major metro station platform roofing project. The project is now in full operation, and the performance of our prepainted aluminum coil with PE coating and PVDF coating has proven to exceed expectations. The roofing panels demonstrate exceptional durability, visual appeal, and long-term stability in a challenging urban transit environment.
The metro station platform required a roofing system that combined strength, lightweight structure, and modern aesthetics. With thousands of passengers using the station every day, the materials needed to ensure safety, reliability, and ease of maintenance. Hanchen Metal supplied high-quality colored aluminum coil with a thickness of 1 mm and above, ensuring rigidity while keeping the panels lightweight for efficient installation. Both PVDF-coated and PE-coated options were customized to meet different sections of the platform canopy, guaranteeing performance and cost efficiency.

Client Concerns & Our Solutions

Client Priorities
During project planning, the client raised several key concerns:
- Weather resistance: The roof needed to withstand heavy rain, wind, and direct UV exposure.
- Color stability: Color coated aluminum coil had to maintain consistent color Performance.
- Fire and safety performance: Panels had to comply with strict public safety requirements.
- Structural strength: With large spans, the roofing system required excellent rigidity.
- Low maintenance: The client wanted long-term performance with reduced upkeep.
Our Solutions
To address these needs, Hanchen Metal provided a combination of advanced materials and customization:
- Prepainted aluminum coil with thickness ≥ 1 mm ensured durability without excess weight.
- PVDF coating was applied in critical areas, offering outstanding UV resistance, anti-corrosion performance, and up to 20 years of color retention.
- Customized colors were matched with the station's architectural design using the RAL system.
- The coils' high flatness and easy formability simplified installation, reducing time and labor costs.

Recommendation for Industry Peers
This project highlights why developers and contractors should consider color coated aluminum coil, especially prepainted aluminum coil with PVDF coating, for large-scale infrastructure. For applications such as metro stations, airports, ceilings, ACP panels, sandwich panels, and roofing systems, the following best practices are recommended:
Thickness
Use thickness of 1 mm or more for structural strength.
Coating Type
Choose PVDF coating for long-term outdoor exposure; PE coating for cost-effective areas.
Color Performance
Select RAL-matched colors for consistent architectural appearance.
Using Environment
Rely on colored aluminum coil for its lightweight, corrosion-resistant, and low-maintenance qualities.
