Double‑curved aluminum panel is a shaped aluminum panel formed by overlapping arcs of different axial directions on one single surface. Fabricated from aluminum alloy, it achieves sophisticated bi‑directional curved structures through multi‑point stretching and double‑curve forming technology.
Radian, curvature and dimensions are customizable to create unique 3D curved surfaces for architectural design needs. A variety of surface finishes such as PVDF coating and powder coating are available to satisfy decorative requirements for diverse architectural styles.
With sleek double‑curve contours and premium metallic texture, double‑curved aluminum panels are widely used for large‑scale building facades, rooftops and other structures requiring extensive curved surfaces, including landmark constructions such as modern museums, art exhibition centers and airport terminals.
• High physical strength, good impact resistance, resistance to deformation
• Extremely lightweight, with a high safety factor for the facade
• Adopting surface treatment methods that comply with international standards (such as European and American standards), it features excellent weather resistance and Class A2 fire performance, which can resist harsh environments such as ultraviolet rays, seawater and wind-sand erosion, and enjoy a long warranty period
• Unique double‑curved surface design for seamless compatibility with various building structures
• Highly customisable, available in various sizes, thicknesses, colors, and shapes to meet different design requirements and achieve the design effect

1. Surveying & Setting Out Release vertical and horizontal control lines according to 3D construction drawings, mark embedded parts and keel layout positions, strictly control the three-dimensional flatness and radian benchmark of the base wall.
2. Fix Embedded Components & Main Keels Install expansion bolts or pre-buried steel plates on concrete main structure; erect vertical and horizontal galvanized steel or aluminum alloy keels, repeatedly adjust keel three-dimensional coordinates to match the double curved radian of panels.
3. Pre-Check Numbered Panels Classify double curved panels by factory serial numbers, inspect surface coating, radian accuracy and back hanging lugs, prepare foam backer rods and weather-resistant sealant.
4. Sequential Panel Hanging & Position Adjustment Hook the panel hanging lugs onto adjustable keel brackets, temporarily fasten bolts. Fine-tune each panel’s horizontal, vertical and bidirectional radian one by one to ensure smooth transition between adjacent curved surfaces and uniform joint width.
5. Waterproof Sealing Treatment Fill the panel gaps with closed-cell foam backer rods, inject neutral weather-proof silicone sealant evenly, smooth the glue surface to avoid hollow bubbles, cracks and water seepage hidden dangers.
6. Edge Capping & Completion Inspection Install customized curved closing trims for top, bottom and corner edges. Overall inspect radian continuity, surface flatness, sealing integrity and fastener fastening tightness.

· Install panels strictly in factory serial order to avoid radian dislocation and surface unevenness;
· All keels must be positioned according to 3D curved data to ensure consistent bidirectional curvature of the whole facade;
· Sealant construction shall be carried out under dry, dust-free and above 5℃ environment;
· Reserved expansion joints shall match local temperature difference to prevent panel arching and deformation caused by thermal expansion and contraction.
1. Landmark Complex Curtain Wall Large-area hyperbolic and spherical double curved panels create distinctive flowing building outlines, widely applied in cultural centers, exhibition halls, grand theatres and commercial complex landmarks, forming unique high-end architectural visual impacts when matched with glass curtain walls.
2. Spherical & Saddle-Shaped Canopy Custom double curved panels make dome and saddle-shaped outdoor canopies, with smooth three-dimensional radian, good waterproof and weather resistance, suitable for entrance drop-offs, plaza sunshades and stadium overhangs.
3. Special-Shaped Interior Art Decoration Saddle curved and irregular double curved panels are used for lobby curved ceilings, artistic background walls and special-shaped wrapping columns of hotels, shopping malls and museums, with optional wood grain and metallic finishes to present advanced artistic space texture.
4. High-End Public & Transportation Buildings Applicable to airport terminals, subway stations and science museums with complex curved modelling, lightweight, fireproof and long service life to meet high-standard long-term public building decoration demands.
