JIASE ALUMINUM supplied 30,000㎡ of high-precision double-curved aluminum panels for the iconic exterior facade of Jingning Stadium in Gansu, China. The project adopts the design concept of “Green Hills & Fruit Mounds”, featuring apple-shaped curved surfaces and terrace-inspired elements. As the core material, double-curved aluminum panels perfectly realize the organic, flowing architectural form while meeting strict requirements for wind resistance, seismic performance, weather durability, and visual aesthetics.

Client Design Requirements
Organic & Dynamic Architectural FormThe stadium features a complex irregular shape inspired by local “apple and terrace” elements, requiring continuous, smooth, three-dimensional curved surfaces across the entire facade. Traditional flat or single-curved panels cannot achieve the seamless, flowing effect demanded by the design.
High-Performance & Long-Term DurabilityThe facade system must withstand strong winds, temperature changes, rain, and UV exposure; provide excellent corrosion resistance, color stability, and self-cleaning performance; and ensure a service life of over 50 years with minimal maintenance.
How Double-Curved Aluminum Panels Elevate the Stadium
Perfectly Realize “Apple-Type” Organic CurvesJIASE ALUMINUM double-curved aluminum panels adopt advanced 3D stretching & CNC forming technology, with a curvature accuracy controlled within ±0.3mm, ensuring no wrinkles, no rebound, and smooth, continuous surfaces. Each panel is custom-shaped in two directions (double curvature), faithfully reproducing the natural, dynamic “apple-shaped” facade and making the stadium a new local landmark.
Seamless & Flowing Visual IntegrityDifferent from flat or single-curved panels, double-curved aluminum panels create a unified, rhythmic, sculptural effect across the entire building envelope. The smooth curves interact with natural light, producing rich light and shadow changes that highlight the modern, energetic atmosphere of sports architecture while maintaining overall visual consistency.
Superior Weather Resistance & Color StabilityAll double-curved panels are finished with PVDF fluorocarbon coating (three-coat, two-bake process), providing outstanding UV resistance, fade resistance, and corrosion resistance. Even in harsh outdoor conditions, the panels maintain long-term color uniformity and surface smoothness, significantly reducing maintenance costs and extending the facade’s service life.
High Structural Rigidity & Wind/Seismic SafetyThe double-curved design greatly enhances panel stiffness compared to flat sheets, effectively resisting deformation under strong wind loads. The aerodynamic curved shape optimizes wind pressure distribution, while the lightweight aluminum material reduces the building’s overall load, improving seismic performance and overall structural safety.
Acoustic & Functional CompatibilityCombined with local perforated aluminum panels, the double-curved facade system helps optimize external sound insulation and internal acoustic environment. The curved surface design also improves rainwater drainage efficiency, reducing water leakage risks and ensuring long-term reliable operation of the facade system.
Digital Manufacturing & Precise InstallationJIASE ALUMINUM adopts a full BIM + digital manufacturing workflow: 3D modeling → CNC mold making → precision forming → automated spraying → on-site 3D positioning installation. This process ensures strict control over each panel’s size, curvature, and color, enabling efficient, high-quality installation even for complex irregular facades.
As a professional manufacturer specializing in high-precision double-curved aluminum panels, JIASE ALUMINUM operates a modern production base covering over 100 mu, equipped with imported 6000KW laser cutting machines, CNC bending machines, 3D stretching forming equipment, and automated PVDF spraying lines. Every double-curved panel undergoes strict inspection for curvature accuracy, flatness, color difference, coating thickness, and structural strength before shipment, ensuring 100% compliance with design and quality standards.
