Dongyang North Railway Station Sunshade Canopy Project
The Dongyang North Railway Station, located in Zhejiang, China, required a sophisticated external sunshade roof as part of its architectural design. The project aimed to provide effective sun shading while also enhancing the station's aesthetic appearance. To achieve this, custom aluminum panels were used to match the curved sunshade canopy design of the station.

| Project Challenges
The design of the sunshade roof involved several challenges that needed to be addressed before construction could begin. The main difficulties included the non-flat roof design, the need for precise measurements, and the selection of appropriate materials.
1. Non-flat Sunshade Roof Design
The sunshade roof 's curved design required the custom aluminum panels to fit the exact curves of the structure, ensuring both structural stability and aesthetic continuity.
2. Accurate Measurement of sunshade Canopy Roof
The curved roof presented complex geometry, which was difficult to capture with traditional measurement methods. The challenge was to measure the exact curves, angles, and dimensions with sufficient precision to ensure that the panels would fit perfectly during installation.
3. Customization of Aluminum Panels
Since the roof surface is not flat , each aluminum panel needed to be custom-designed to fit the specific geometry of the roof at various points. This required high precision to ensure that the panels aligned correctly with the curved structure and maintained consistency across the entire roof.
4. Material Durability and Corrosion Resistance
Given that the canopy roof must be exposed to outdoor conditions, the aluminium sheet must possess durability and corrosion resistance, maintaining its aesthetic quality even after prolonged exposure to sunlight.
| Benefits of Using Aluminum Panels for Outdoor Sunshade Canopy Roof
1. Lightweight and Strong
Aluminum panels offer a high strength-to-weight ratio, making them ideal for large-scale canopy structures. Their light weight reduces structural load while maintaining the necessary durability for outdoor use.
2. Adaptability to Curved Designs
Aluminium panels can be customised into various shapes to accommodate complex curves, ensuring seamless integration with non-planar roof geometries. This flexibility renders them highly suitable for modern architectural shading designs.
3. Durability and Corrosion Resistance
Aluminum is naturally resistant to corrosion and, when combined with specialized surface treatments, can withstand harsh outdoor conditions such as humidity, rain, and UV exposure. This ensures long-term structural performance and maintains aesthetic appeal over time.
4. Low Maintenance
After installed, aluminum panels require minimal upkeep compared with other materials, making them a cost-effective choice for public infrastructure projects.
5. Aesthetic Versatility
With a range of finishes and coatings available, aluminum panels can enhance the visual impact of a building, complementing both functional and architectural goals.
| Project Solutions
To tackle the challenges of the curved roof design, 3D laser scanning technology played a vital role in every step of the project, from measurement to production and installation. By providing precise and reliable data, it enabled the team to make informed decisions at each stage of the process.
1. Precise Measurement with 3D Scanning
Traditional measurement methods often lack the required precision and are time-consuming, particularly when dealing with complex geometries such as roof curves. By employing 3D scanning technology, the intricate curves and angles of the roof were captured with millimetre-level accuracy. This enabled the design team to create detailed models, ensuring the aluminium panels were manufactured to precise specifications and thereby avoiding potential misalignment issues during installation.
2. Custom Aluminum Panel Production
High-precision data acquisition of the roof's geometric structure was achieved using 3D laser scanning technology. This enabled the team to custom-design aluminium panels tailored to the roof structure. The technology's accuracy ensured precise alignment between the panels and the structure, eliminating the need for adjustments during installation.
3. Selecting Durable and Corrosion-Resistant Materials
Specialized finish treatments enhance these aluminium panels to resist corrosion and endure various outdoor conditions. As a result, they retain their durability, structural integrity, and visual appeal even under intense sunlight.
