Flat
Flat facets can approximate a curved envelope where the visual tolerance and joint layout allow.
JUCHANG ALUMINUM / FORM SERIES
Double-curved
aluminum panels.
Custom solid aluminum cladding for freeform facades, sweeping canopies and sculptural interiors. Start with your 3D surface and panel layout.

01 / GEOMETRY
Read the curve
at panel scale.
A facade can look doubly curved while using a mix of flat, single-curved and double-curved panels. The individual panel geometry determines the forming route and tooling.
Single-curved
A cylindrical surface bends across the arc and stays straight along its axis. Send radius, chord and section dimensions.
Double-curved
Dome-like or saddle-like geometry changes in two directions. Send a 3D surface, panel boundaries and key sections.
02 / APPLICATIONS
Where compound
curves fit.
Resolve the panel joints, support interfaces and finish early, especially where the surface wraps around corners or transitions overhead.
Freeform facades
Podiums, cultural buildings and curved transitions. Establish the joint grid and backing system before releasing the panel model.
Canopies & soffits
Entrance shells and overhead surfaces. Coordinate drainage, access, concealed fixings and the transition to adjacent finishes.
Columns & interiors
Tapered wraps, sculptural ceilings and feature walls. Review visible seams, lighting and finish samples from the intended viewing angle.
03 / SPECIFIER'S DESK
Define what
goes on the drawing.
Project dimensions, tolerances, structural details and coating performance are subject to drawing review and agreement.
- Sheet & geometry
- Specify alloy, temper and nominal thickness where known. Share surface model, trim boundaries, returns and panel IDs. Formability depends on geometry, material and tooling.
- Surface finish
- State color reference, gloss and exposure. If a project calls for AAMA 2604 or 2605, identify the required edition and ask for documentation covering the proposed coating system.
- Fixings & interfaces
- Provide the supporting system, joint dimensions, bracket locations and movement allowance. Confirm who is responsible for the subframe and project engineering.
- Inspection & delivery
- Agree on geometry checkpoints, finish sample or mock-up, panel numbering, crate protection and site delivery sequence before production.
04 / DESIGN TO DELIVERY
From model to panel.
Review geometry
Check curvature, units, revision and support details. Group repeatable panel shapes.
Confirm scope
Review segmentation, tooling needs, quantities, finish and destination before quoting.
Approve details
Sign off on shop drawings and finish samples. Agree whether a trial panel or mock-up is required.
Inspect & pack
Check against the approved documents and identify each panel for its location and shipment.
Buyer questions
Can I start with a render or PDF?
Yes. Share the design intent and rough dimensions for an initial discussion. A coordinated surface model and panel schedule are needed to assess tooling and firm up pricing.
What affects the price per square meter?
Curvature, individual panel sizes, unique shape count, tooling, edge returns, finish, quantities and packing can all affect price. Include the panel schedule so repeat shapes can be identified.
Can a double-curved facade use simpler panels?
In some designs, single-curved or faceted panels can follow the envelope within agreed visual and geometric tolerances. Compare joint alignment and reflected light on a representative mock-up.
