SINGLE CURVED ALUMINUM PANELS
ALUPANELIX

Material: 3003 or 5005 aluminum alloy; temper and suitability to forming and finish review.

Thickness range: 1.5–4.0 mm. Initial selection references: 1.5–2.0 mm for interior ceilings or feature walls; 2.5–3.0 mm for exterior cladding or column covers. Final thickness depends on spans, supports and design loads.

Developed width: Normally up to 1500 mm before forming, subject to edge returns, tooling and finish capacity.

Panel length: Normally up to 4000 mm; special projects up to 6000 mm subject to forming, reinforcement, coating and transport review.

Bending radius: A preliminary minimum radius around 15 × sheet thickness may be reviewed for suitable combinations. It is not a universal forming limit; confirm radius datum, alloy temper, thickness, edge geometry and tooling through feasibility review and trial forming.

Reinforcement: Rear aluminum channel stiffeners; 400–600 mm spacing is an initial reference only. Stiffener size, spacing and connections must be designed for panel geometry, self-weight and project wind loads.

Mounting details: Compatible aluminum brackets or mounting ears, riveted or welded as detailed. Dry-fixed, clip-in or close-joint layouts subject to the engineered support and fixing design.

Panel weight: Calculate from actual alloy, thickness, developed area, folded returns, stiffeners and fittings. An 8–10 kg/m² estimate for a 2.5–3.0 mm assembly requires confirmation from the panel schedule; it is not a bare-sheet value or a fixed ratio to stone.

Color & appearance: RAL, PANTONE or supplied-sample matching; solid colors, metallic colors, wood-grain and stone effects, subject to physical sample approval.

Performance & inspection: Radius, chord, arc length, dimensions, joints, finish and fixing details to approved drawings. Structural and fire performance follow the specified complete assembly and applicable test documentation.

SURFACE TREATMENTS
PVDF coating: An exterior coating option for curved facades, including demanding coastal exposure with a suitable system. If a film thickness of at least 40 μm is required, confirm the selected coating build, measurement and supplier specification. Color retention, salt-spray performance, maintenance and warranty require supporting documentation.

Polyester (PE) coating: A decorative option for interior panels and suitable sheltered applications. Exterior use and service life depend on the selected formulation and project exposure; confirm the coating specification.

Powder coating: Matt, gloss, sand-textured and other finish options. A 60–80 μm dry-film target can be reviewed against the powder-system specification; suitability and acceptance criteria follow the approved system.

Wood-grain transfer: A wood-look finish on metal for hotels, cultural projects and decorative spaces. Confirm grain direction, transfer process and indoor or outdoor suitability on a formed sample.

Stone-effect finish: A marble- or granite-inspired appearance on curved metal panels. Confirm the pattern, gloss, seam layout and finish durability for the intended exposure.

Anodizing: A metallic finish with a nominal 10–20 μm oxide-film option, subject to alloy, temper, fabrication and process review. Confirm color consistency, surface preparation, sealing and acceptance criteria.

Final dimensions, performance, finish, testing and delivery follow approved drawings, samples and quotation.
