Custom Aluminum Profile
Custom Aluminum Profile & Extruded Shapes
Non-standard aluminum profiles made to your drawing — solar frames, rails, slides, trim and purpose-built cross-sections. If it has a constant section and a function, we can extrude it.
Any constant section, to your drawing
A "specialty" profile is simply one we do not stock — it exists because your product needs that exact shape.
Most aluminum extrusions in the world are non-standard: a solar frame, a conveyor rail, a slide, a trim, a bracket. The catalog parts are the exception. When a standard section almost works, a custom die removes the compromise — the groove, the lip, the mounting face and the wall are set by your assembly, not by what a supplier lists.
We review every custom section for extrudability before tooling: can the alloy fill the shape, will the walls stay uniform, where do the fillets go. That review is part of the quote, not a surprise after the die is cut. Once the die exists, repeats are consistent and the part drops into your line the same way every time.
Profile families we make
Common specialty categories — any can be a fully custom cross-section.
Solar frames
Aluminum solar panel frame profiles with the lip and drain channel a PV module needs; extruded to length and cut to size.
Rails & slides
Aluminum rail extrusion and slideways for conveyors, automation and linear guides — groove and race built into the section.
Trim & edge
Aluminum edge profile and trim for sealing, protection and finish where a clean exposed edge matters.
Brackets & components
Extruded brackets and aluminum extruded component bodies, often finished by CNC to a mounted part.
Industrial LED housing
Extruded housings for industrial LED fixtures (not decorative strip-channel). See our thermal range for LED cooling.
Purpose-built shapes
Multi-cavity, asymmetric or thin-wall sections for a specific function — reviewed for extrudability first.
Typical capabilities
Indicative ranges; final complexity, alloy and tolerance are confirmed against your drawing and press.
Alloys
6063 typical for finish and complex thin-wall; 6061 / 6082 where the section carries load.
Complexity
Multi-cavity and asymmetric sections possible; thin walls and high slenderness need die care. Confirm against shape.
Section size
Profile width to ~350 mm flat (250 mm circumscribed diameter) on our 3600T press; longer and larger sections via Foshan partner network on request.
Tolerance
EN 755 general or precision class, or your tighter print. Thin-wall sections held to a realistic class.
Finish
Anodize Type II / III or powder coat, including color-matched trim and frame lines.
Machining
Holes, slots and faces cut on CNC referenced to the extruded datum (±0.01 mm typical).
Capability figures are conventional in-house ranges (presses 600–3600T). Complexity, alloy and tolerance are confirmed against your drawing and press before tooling.
Design notes for custom profiles
What makes a custom section extrudable and affordable.
Symmetry helps. A section balanced around its center fills more evenly and twists less. Heavy one-sided mass needs more die tuning and a slower run.
Wall balance. Keep walls near-uniform; a thin fin next to a thick web is the classic cause of short die life and fill defects.
Function in the shape. If a groove, lip or hole is part of how the part works, put it in the extrusion rather than milling it later — it is then free per length.
Not decorative strip. We make industrial and structural profiles. Decorative LED strip-channel is a catalog consumer item outside our build-to-print scope.
Questions buyers ask
Short answers before you send a drawing.
Custom profile vs a standard catalog section?
A standard section is cheaper and faster if it fits — but it rarely fits exactly, and you then add operations to make it work. A custom profile puts the function into the extrusion: the groove, lip and mount are free per length, the part drops into your line consistently, and you carry no inventory of near-right standard stock. For recurring volume or a shape a catalog cannot give, custom extrusion is usually the lower total cost.
What is the minimum order and lead time?
MOQ is 500 kg per profile (die amortization). A new die plus first samples typically runs 2–4 weeks depending on complexity; machining, bending and finishing extend the schedule. We return a dated plan with the quote.
Can you extrude a thin-wall or very complex shape?
Often yes, within limits. Thin walls (≥ 1.0 mm typical), high slenderness and many cavities raise die complexity and need review. Send the section; we confirm extrudability and the realistic tolerance class before tooling — no assumption, no surprise.
Do you make decorative LED strip profiles?
No. We make industrial and structural aluminum profiles — including housings for industrial LED fixtures — but decorative LED strip-channel is a catalog consumer product outside our build-to-print scope. For industrial LED thermal management, see our heatsink range.
Have a profile no catalog stocks?
Send the cross-section drawing — we review extrudability and return a DFM report and quote.
