All-Aluminum Welded Cabinet Board

A: An all-aluminum welded cabinet board is a premium-grade furniture panel where aluminum face sheets are permanently joined to solid aluminum edge frames using TIG (Tungsten Inert Gas) welding, creating a monolithic metal panel with a fully seamless edge. Inside, an aluminum honeycomb core provides structural rigidity while keeping the panel lightweight. Unlike mechanically fastened or adhesive-bonded cabinet boards, welded construction eliminates all joints, screws, and glue lines at the edges - delivering a perfectly smooth, watertight, and aesthetically flawless appearance. This is the highest-grade cabinet board available, preferred for luxury kitchens, superyacht interiors, commercial laboratory casework, and high-end architectural millwork where zero visible fasteners and absolute waterproof integrity are non-negotiable.

A: Common specifications:
• Total thickness: 10mm, 15mm, 18mm, 20mm, 25mm, 30mm
• Face sheet thickness: 0.8mm, 1.0mm, 1.2mm, 1.5mm (3003/5052/5083 alloy)
• Core: aluminum honeycomb, cell size 6mm or 8mm, foil thickness 0.04–0.08mm
• Edge frame: solid aluminum profile machined from 6063-T5 or 6061-T6 alloy, thickness matching panel
• Welding method: TIG (GTAW) with 4043/5356 filler rod; optional full-penetration laser welding for 0.8mm skins
• Post-weld treatment: grinding → brushing/polishing → surface coating - weld seam becomes invisible
• Standard panel size: 1220×2440mm, 1220×2745mm, 1220×3050mm; custom up to 1500×4000mm
• Core density: 60–80 kg/m³
• Weight: ~6.0–8.5 kg/m² at 18mm thickness
• Surface finishes: powder coating, anodizing, PVDF, brushed, mirror polish, wood-grain transfer

A: The MOQ for welded cabinet boards is typically 50–100 sheets, reflecting the labor-intensive welding and post-weld finishing process. Custom sizes, special alloys, or premium finishes (mirror polish, custom anodizing) may require 100–150 sheets. Trial orders of 10–20 sheets can be arranged for sampling, though unit pricing will be higher due to the fixed setup cost per production batch. The MOQ is driven by the welding jig preparation, surface treatment line minimums, and post-weld finishing workflow. Please provide your desired dimensions, alloy preference, edge detail, and surface finish for an accurate quotation.

A: Premium applications:
• Luxury residential kitchens: handleless, seamless cabinet doors and drawer fronts - no visible fasteners
• Superyacht & marine interiors: fully waterproof cabinetry for galleys, heads (bathrooms), and wet bars; meets SOLAS fire requirements
• High-end retail & hospitality: boutique store fixtures, hotel reception desks, bar counters requiring flawless aesthetics
• Commercial laboratory casework: chemical-resistant, easy-to-sterilize, fully sealed cabinets for clean environments
• Hospital & healthcare furniture: seamless surfaces with no crevices for bacteria; compatible with aggressive cleaning agents
• Architectural millwork: custom reception counters, wall panels, column wraps with invisible joints
• Outdoor kitchens & BBQ stations: fully weatherproof cabinetry that withstands rain, sun, and temperature extremes
• Cleanroom furniture: zero particle-shedding, fully sealed construction for semiconductor and pharmaceutical facilities

A: ① Invisible edges: post-weld grinding and finishing eliminates the joint line entirely - the panel appears as a single solid aluminum slab
② Absolute waterproof integrity: no adhesive bond line that can fail over time; welded seams are as watertight as the base metal itself
③ Maximum structural strength: the welded edge frame forms a rigid perimeter that dramatically increases torsional and racking resistance compared to adhesive-only panels
④ No adhesive aging: zero organic materials at the edge - no risk of delamination from heat, humidity, UV, or chemical exposure over decades
⑤ Superior screw holding: the solid aluminum edge frame (not honeycomb core) provides strong thread engagement for hinge screws, drawer slides, and connectors - no special inserts required
⑥ Seamless aesthetic: ideal for handleless push-to-open cabinet systems where the edge is a visible design element
⑦ Hygiene compliance: no crevices, seams, or material junctions at edges - meets the most stringent food-safety and healthcare surface standards
⑧ Thermal conductivity: the continuous metal edge conducts heat, allowing the entire panel to be used as a radiant surface in specialized applications

A: Surface finishing is applied after welding and grinding for a uniform appearance across the entire panel including edges:
• Powder coating: matte, satin, or textured; 300+ RAL colors; excellent scratch and chemical resistance - most popular for residential and commercial cabinets
• Anodizing: natural, champagne, bronze, or black; hard-anodized option (60+ micron thickness) for heavy-duty lab and marine applications; produces a deep metallic luster unique to aluminum
• Brushed finish: linear satin grain (180–320 grit) with clear anodized or lacquer seal - popular for contemporary European kitchen aesthetics
• Mirror polish: high-reflectivity surface achieved through progressive polishing (up to 0.02μm Ra) - for ultra-luxury retail and yacht interiors
• PVDF coating: premium weather-resistant finish for outdoor kitchen and exterior architectural applications
• Heat-transfer wood-grain: realistic timber patterns applied to aluminum surface - combines wood aesthetic with aluminum performance
• PET film: high-gloss or super-matte anti-fingerprint lamination for modern handleless kitchens
• Custom etching/engraving: logo, pattern, or artwork chemically etched or laser-engraved into the surface

A: Yes. Constructed entirely from aluminum (skins, honeycomb core, and welded edge frame), the panel is 100% metal and rated Class A non-combustible (GB 8624) / Class A1 (EN 13501-1). It will not burn, melt through, produce flaming droplets, or release toxic smoke. This fire performance significantly exceeds that of wood, MDF, plywood, and even many 'fire-rated' composite panels. For marine applications, the panel meets IMO FTP Code requirements (SOLAS) when using appropriate surface coatings. Independent fire test certificates are available upon request.

A: • Standard stock items (white/grey powder coat, 18mm, 1220×2440mm): 10–15 working days
• Custom size, stock finish: 15–20 working days
• Custom color or finish (powder coat / anodizing): 20–25 working days
• Premium finishes (mirror polish, custom anodizing): 25–35 working days
• Large project orders: production schedule confirmed upon PO review; phased delivery available
Note: The welding, grinding, and polishing processes add 5–10 working days compared to non-welded cabinet boards. This is necessary to achieve the seamless edge quality. Rush orders for smaller quantities may be possible at an expediting surcharge. We recommend placing orders 6–8 weeks before required on-site delivery for large projects.

A: Packaging: Premium protective protocol due to the high-value finish:
• Each panel is wrapped in 60μm low-tack PE protective film (no adhesive residue upon removal)
• Panels are separated by 5mm EPE foam sheets and stacked face-to-face
• The stack is enclosed with 5mm MDF cover boards top and bottom, then wrapped in waterproof VCI (Volatile Corrosion Inhibitor) paper for export shipments
• Crating: reinforced plywood crate with internal foam padding at all contact points; panels are secured with non-abrasive nylon straps (never steel bands on finished edges)
Shipping:
• Domestic: air-ride suspension trucking; white-glove inside delivery available for premium projects
• International: FCL 20GP/40HQ only (LCL not recommended due to handling risk on premium finishes); CIF/FOB standard; DDP for select markets
• Sample shipping: plywood-boxed sample with a welded edge demo piece; DHL/FedEx for international
Every shipment includes a QC inspection report, humidity indicator, and tilt/shock indicators.

A: Fabrication approach:
Cutting to size:
• Use a CNC router or panel saw with a TCT triple-chip blade (100 teeth for 300mm blade)
• Cut from the face side down to minimize burr on the visible surface
• Cutting speed: 2,500–3,500 RPM for 18mm panels - slower than wood to manage heat
• Coolant mist recommended for thick panels (>20mm) to avoid thermal distortion
Edge considerations:
• The welded frame edge is already finished - do not apply edge banding; it would degrade the seamless look
• For field-cut edges (non-factory edges), apply a matching aluminum trim profile or touch-up paint
Drilling & hardware:
• Hinge cups: drill with a 35mm Forstner bit at 1,500–2,000 RPM using a drill press; use cutting oil for clean holes
• Shelf pin holes: 5mm system holes work perfectly; the solid edge frame holds shelf pins securely
• Screws: self-tapping stainless steel screws (A2/A4) directly into the solid edge frame - no plastic inserts needed
• Heavy hardware (lift systems, soft-close mechanisms): pre-drill and tap M4/M5 threads into the edge frame
Assembly:
• Cabinet box: use aluminum corner brackets with machine screws into the edge frame - the solid frame provides strong, repeatable connections
• Alternatively, cam-lock (Minifix) connectors work well when the cam housing sits in the face sheet and the bolt threads into the edge frame
Finishing care:
• Handle with clean cotton gloves during assembly to prevent fingerprints on premium finishes
• Use felt pads on all jig and clamp contact surfaces
• Clean finished cabinets with pH-neutral aluminum cleaner and microfiber cloth
