Aluminium U Type Tube — Processing, Forming & Joining
Bending (U Channel)
Bend along the extrusion direction for better stability; use multi-pass gradual bends to reduce ripples.
Protect visible surfaces with soft pads / V-block guards to prevent clamp marks.
Typical angular tolerance ±1°; tighter limits available upon agreement.
Appearance parts: For the most uniform look, anodize/powder-coat after bending. If finishing first, accept the risk of whitening/halo in the bend zone.
Welding (MIG/TIG; ER4043 / ER5356)
Process: MIG/TIG (AC). Shielding gas: Argon (trace helium optional to increase heat input).
Filler selection: ER4043 flows well with lower cracking risk (anodized color appears slightly darker); ER5356 offers higher strength and closer color match to base metal—preferred for marine / higher-strength service.
Prep: Degrease → remove oxide (dedicated stainless-steel brush) → dry → weld → grind/dress.
Acceptance: Appearance grade, dimensions, leak integrity; dye-penetrant and/or pressure/helium leak tests as required.
Slotting / Punching
Slot end radius: R ≥ 0.5 × slot width to avoid stress concentration at sharp ends.
Edge & pitch rules (guideline): Edge distance ≥ 2 × T; hole-to-hole pitch ≥ 3 × T (or per drawing).
Process choice: Small batches/high precision → CNC milling; large volume → progressive stamping.
Deburring: Manual or tumbling; no burrs on show faces. Thoroughly clean before anodizing/powder coating.
Machining
Allowances: Saw-cut with +1.5–3 mm stock, then finish machine; machine mating and visible faces last.
Tooling: Sharp carbide, positive rake; ample coolant (aluminum-grade cutting fluid).
Finish consistency: For minimal color variation, finish machine then anodize/coat.
Aluminum U Type Tube Surface Finishes
Anodizing
Typical thickness: 8–12 μm (indoor), 15–25 μm (outdoor), 25–50 μm (hard anodizing).
Colors: natural, black, champagne, bronze, gold (matte or gloss).
Film grows inward + outward; for critical fits, allow ~0.5 × film thickness as clearance.
Sharp edges coat thinner—recommend edge radius R ≥ 0.2–0.5 mm.
Sealing (hot water or nickel salt). Verify thickness / color variation / sealing quality per project spec.
Powder Coating
Typical film 60–120 μm; any RAL color, gloss, or texture. Excellent coverage and weathering—ideal outdoors.
Sharp edges and hanger points need masking notes on drawings; chamfer/round edges for better coverage.
Acceptance focuses on film thickness, adhesion, impact resistance, and salt-spray performance.
Electrophoretic Coating (E-coat)
Thin, very uniform film; clear, tea, coffee, bronze tones with strong metallic look.
For higher corrosion resistance and refined appearance, combine with anodizing (anodize first, then clear e-coat).
Brushed / Polished
Common grits #180 / #240, up to #8 mirror.
Recommend "brush first, then anodize” to lock in grain and improve wear resistance.
Specify grain direction on show faces; apply PE protective film through production & logistics.
Mill Finish
As-extruded surface—suitable for subsequent machining or secondary finishing.
Minor extrusion lines/scratches may be present; for decorative show faces, prefer anodizing or powder coating for a stable appearance.
Aluminium U Type Tube Applications
Architectural Edge Trim / Door & Window Beads
Used for edge finishing and seam covering on curtain walls, doors/windows, and wall panels, with emphasis on uniform appearance and straight, clean edges. Choose décor-friendly alloys and finishes (e.g., anodizing or powder coating). Typical assembly uses self-tapping screws, rivets, or structural adhesive. At ordering, specify visible-face orientation and color consistency requirements.
LED Channels / Luminaire Housings
Provide light guiding, heat dissipation, and shielding while keeping weight low and appearance clean. Use rounded internal transitions to ease LED-strip installation. Exterior finishes are commonly black anodizing or sandblast + anodizing. Specify cover clip details, fit features, and tolerances on drawings. Apply protective film throughout transport.
Display & Furniture Frames
For racks, showcases, partitions, and furniture frames—balancing stiffness and aesthetics. Prioritize brushed + anodized finishes for visible décor; choose higher-strength alloys for load-bearing sections. Common joining: bending, corner brackets, or modular profile assembly. Hole spacing and edge distances per drawing.
Equipment Guards / Edge Protection / Cabinets
For machine enclosures and edge protection where impact resistance, scratch resistance, and cleanability matter. Pair with durable finishes such as powder coating or hard anodizing. Control edge distances, shapes, and positional tolerances for holes/slots per drawings, and remove burrs and sharp edges on show faces.
Storage Racking / Logistics Bumper Strips
Used as rack edge guards, conveyor lane stoppers, and pallet borders—prioritizing stiffness and wear resistance. Select alloys with a good strength-toughness balance; ensure straightness and consistency on long lengths. Consider wear-resistant textured powder coatings. Assembly typically with screws or rivets; add local reinforcement around hole zones.
Vehicle Interiors / Conversions (RV / Van / Truck)
Applied as interior edge trim, track covers, and guards, focusing on lightweight and corrosion resistance. Bending radius and process depend on alloy and temper. For visible parts, prefer black anodizing or a highly consistent coating system; control color variation and scratch risk on show faces.
HVAC / MEP Service-Line Capping
Covers edges of ducts, piping, and cable trays; requires weatherability and easy maintenance. Outdoors, use weather-resistant anodizing or powder coating. Clearly define mating relations at clip/hinge features on drawings. For transport, use end caps and pallet restraints to prevent deformation.
Offshore / Chemical Equipment Shrouds
For long-term exposure to salt spray or process media, choose corrosion-resistant alloys or apply heavy-duty protective coating systems on structural alloys. Use stainless fasteners with proper galvanic isolation. Documentation can include material certificates and environmental compliance declarations to support bidding and acceptance.
Quality & Packaging
Process Control Multi-zone, PID-controlled artificial aging with temperature uniformity ±2 °C; 100% stretch-straightening.
Consistency Same-batch, same-tank anodizing for color uniformity; graded control of show/non-show faces; full batch traceability end-to-end.
Inspection 100% dimensional and visual checks; mechanical properties sampled as required. Third-party inspection available (e.g., SGS / BV).
Packaging PE protective film → anti-scratch interleaves → shrink wrap/Kraft paper → end protectors → fumigated pallets/crates. Container reinforcement schemes available on request.

FAQ
Q: What's the difference between a U channel and a C channel?
A: U channels typically have two legs of equal height. C channels are more common in structural parts, with geometry oriented for load-bearing and usually thicker walls.
Q: Can I specify different thicknesses for legs and web?
A: Yes. Use T1/T2 to define differential wall, and indicate R1/R2 for inside/outside corner radii.
Q: How is weight calculated?
A: By cross-sectional area × density (≈ 2.70 g/cm³) as a theoretical value. Normal production tolerances apply to batch weight.
Q: How tight can length tolerance be?
A: Typical cut tolerance is ±1.0–2.0 mm; CNC cut-to-length can be tightened further.
Q: Which alloy is most stable for a black finish?
A: 6063-T5/T6 offers the most stable anodized color—recommended for decorative applications.
Q: Are welding and bonding compatible?
A: 6xxx/5xxx series support standard MIG/TIG welding. Structural bonding is possible with industrial adhesives (surface cleaning/roughening or anodize pretreatment required). We'll propose a welding plan and filler wire (e.g., ER4043/ER5356) based on your alloy and finish.
