DOUBLE CURVED ALUMINUM PANELS
ALUPANELIX

Material: 3003 / 5005 / 5052 aluminum alloy; temper, formability, welding and finish compatibility to project review.

Thickness options: 2.0 / 2.5 / 3.0 / 4.0 / 5.0 mm; selected according to curvature, span, forming process and structural requirements.

Panel size reference: Up to 1500 × 4000 mm, subject to 3D geometry, developed blank dimensions, tooling, coating and transport capacity. Larger surfaces can be divided into coordinated segments; joint layout requires approval.

Model & fabrication: 3D modelling and surface analysis → panel division and blank/tooling review → CNC-controlled forming, multi-pass forming or mould pressing as appropriate → joining, reinforcement and finishing. A simple rolling route is not suitable for every doubly curved surface.

Reinforcement: Rear aluminum stiffeners and connections designed for panel geometry, wind loads, self-weight and thermal movement. Spacing and attachment details follow the approved structural design.

Panel weight: Calculated for the selected alloy, thickness, developed panel area, folded returns, stiffeners and fittings. Confirm the assembly weight in the approved panel schedule.

Surface treatments: PVDF coating, polyester (PE) coating, powder coating, wood-grain or stone-effect finishes; anodizing subject to alloy, forming and sample review.

Color matching: RAL / PANTONE references or customer-supplied samples. Final color, gloss, texture and pattern alignment to physical sample approval.

Installation options: Three-dimensionally adjustable hanging connections, angle-bracket dry fixing or close-joint systems, as detailed by the project designer.

Performance & inspection: Curvature, reference points, panel boundaries, joints, welds, reinforcement, fixing positions and finish to agreed criteria. Fire classification and other performance claims require applicable product or assembly documentation.

SURFACE TREATMENTS
PVDF coating: For exterior double-curved cladding, including coastal projects with a suitable system. A three-coat/two-bake process can be reviewed where specified. UV, acid-rain and color-retention performance depend on the selected system, pretreatment, exposure and supporting supplier documentation.

Polyester (PE) coating: A decorative option with varied colors for interior sculptural panels. Confirm formulation, exposure suitability and written performance terms; no universal service life is assumed.

Powder coating: For interior curved ceilings and other applications with an appropriate powder grade. Coordinate forming and coating sequence and inspect representative samples; flexibility and crack resistance require system-specific confirmation.

Wood-grain transfer: Wood-look decorative effects for hotels and cultural projects. Review transfer feasibility, grain direction and pattern continuity on a representative double-curved sample; fire and moisture requirements apply to the complete product or assembly.

Stone-effect finish: A stone-inspired appearance on lightweight curved metal cladding for shaped columns and facades. Approve texture, pattern placement, joints and exposure suitability.

Anodizing: Metallic appearance options, including silver and bronze references, for interior art features. Alloy, temper, welds and forming affect consistency; confirm process, finish and sealing with a sample.

Final geometry, finish performance, fire classification, warranty and delivery follow approved models, drawings, test documentation and quotation.
