Aluminum-Wood Door

A: An aluminum-wood door (also known as an aluminum-clad wood door or 铝木门 in Chinese) is a hybrid door that combines a solid wood or engineered wood door leaf with a protective and decorative aluminum cladding on the exterior face, interior face, or both. The aluminum cladding - typically 1.0–2.0mm thick aluminum sheet with powder coating, PVDF, or wood-grain transfer - provides weather protection, impact resistance, and design versatility, while the wood core provides warmth, acoustic insulation, and the traditional feel of a solid wood door. The aluminum-wood door inherits the best qualities of both materials: the durability and low maintenance of aluminum on the outside, and the natural beauty and solid feel of wood on the inside. It is particularly popular for villa entrance doors, balcony doors, and high-end residential applications where the exterior face must withstand weather while the interior face provides a warm, luxurious wood aesthetic.

A: Common specifications:
· Door thickness: 40mm, 45mm, 50mm, 55mm, 60mm (55mm most common for entrance doors)
· Wood core: solid wood (oak, teak, meranti), engineered wood (LVL/laminated timber), or wood-stave core with aluminum honeycomb fill
· Aluminum cladding thickness: 1.0mm, 1.2mm, 1.5mm, 2.0mm (exterior face - thicker for security and weather resistance; interior face - 0.8–1.0mm)
· Aluminum alloy: 6063-T5 for extruded frame profiles; 3003-H14 or 5052-H32 for sheet cladding
· Aluminum frame: aluminum edge profiles (rebated or square) wrap the wood core perimeter - protects the vulnerable wood edges from moisture and impact
· Standard door sizes:
- Single entrance door: 2100×1000×55mm, 2400×1100×55mm, 2500×1200×60mm
- Interior room door: 2100×800/900×40mm
- Double door: as single ×2 with meeting stile
- Custom sizes available to order
· Weight: approximately 28–40 kg for a standard 2100×1000mm entrance door
· Glazing options: double or triple glazed insulated glass unit (IGU) integrated into the door leaf
· Hardware: multi-point locking system (3–5 locking points), stainless steel hinges (3 or 4, rated for door weight), lever handle + deadbolt + viewer
· Weather sealing: EPDM rubber gaskets on aluminum frame - triple-seal system for air/water/wind tightness
· Thermal break: polyamide (PA66) thermal break strip in the aluminum frame profile - prevents cold bridging for energy-efficient doors

A: The typical MOQ is 10–30 doors for standard sizes and finishes. For custom dimensions or special wood species, the MOQ is evaluated case-by-case. Single custom doors are accepted with a customization surcharge. A sample door leaf section (cross-section cutaway showing wood-aluminum construction) is available for quality evaluation. Please provide your door schedule (quantity, opening dimensions, swing direction, exterior/interior finish requirements, glazing specifications) for a quotation.

A: Common applications:
· Villa and luxury residence entrance doors: aluminum exterior face withstands weather, wood interior face provides warmth - the classic high-end residential entry door
· Apartment front doors: fire-rated and security-rated aluminum-wood doors for multi-family residential - combines safety with aesthetics
· Balcony and terrace doors: aluminum-wood sliding or French doors - weather-resistant exterior, natural wood interior
· Garden and patio doors: large-format aluminum-wood doors that open the home to the garden - indoor-outdoor living transition
· Hotel suite entrance doors: premium sound-insulated doors with aluminum-wood construction - meets hotel fire and acoustic standards
· Office and commercial doors: executive office doors, boardroom doors - aluminum durability + wood prestige
· Heritage and conservation area doors: aluminum-wood doors that replicate traditional timber door appearance on the street-facing side (wood-grain aluminum) while providing modern thermal and security performance
· Passive house and high-performance buildings: aluminum-wood doors with thermal break and triple glazing - U-value as low as 0.8 W/m²K
· Coastal and high-humidity locations: aluminum exterior protects the wood core from salt spray and moisture - wood door appearance without the maintenance

A: ① Best of both worlds - weather protection + natural warmth: solid wood doors deteriorate rapidly when exposed to weather (rain, sun, temperature swings). All-aluminum doors, while durable, can feel cold and industrial. The aluminum-wood door provides weather-resistant aluminum on the outside and warm, natural wood on the inside - no compromise.
② Protected wood edges - the failure point of solid wood doors: wood doors fail first at the edges - the top and bottom edges absorb moisture, causing swelling, paint peeling, and rot. The aluminum perimeter frame on an aluminum-wood door encapsulates and protects all wood edges - the wood core is hermetically sealed against moisture ingress.
③ No warping or swelling: the aluminum frame and face cladding constrain the wood core, preventing the dimensional movement that causes solid wood doors to warp, stick, and jam seasonally. The door operates smoothly year-round.
④ Superior thermal insulation: the wood core provides natural thermal insulation (wood thermal conductivity ~0.12 W/m·K vs. aluminum ~160 W/m·K). Combined with a thermal break in the aluminum frame, aluminum-wood doors achieve U-values of 0.8–1.5 W/m²K - compliant with energy codes and passive house standards.
⑤ Excellent acoustic performance: the solid wood core provides high mass for sound attenuation. With perimeter acoustic seals, aluminum-wood doors achieve STC 32–42 - superior to all-aluminum doors and comparable to solid-core wood doors.
⑥ Premium security: aluminum cladding on the exterior face (1.2–2.0mm thick) cannot be kicked through or crowbarred. Combined with a multi-point locking system engaging the aluminum frame, the door provides security beyond what a solid wood door alone can offer.
⑦ Design versatility: aluminum-wood doors offer two independent design faces - the exterior face can be powder-coated in any RAL color to match the building facade, while the interior face can be natural wood (oak, walnut, teak) stained to match interior joinery. Two doors in one.
⑧ Low maintenance: the aluminum exterior never needs painting or sealing. The wood interior needs only periodic cleaning and occasional re-oiling (every 3–5 years). Compared to solid wood exterior doors that require repainting every 2–3 years, maintenance is dramatically reduced.
⑨ Long service life: with the wood core protected from the elements by aluminum, the door's structural integrity is preserved for 30+ years. Solid wood exterior doors typically need replacement within 15–20 years due to weather degradation.
⑩ Fire-rated options: aluminum-wood doors can be certified as fire doors (FD30, FD60) with appropriate fire-rated wood cores, intumescent seals, and fire-rated glazing. This combines fire safety with premium aesthetics - essential for apartment entrance doors and hotel corridors.

A: Wood core options:
· Oak (white/red): the premier choice - beautiful grain, hard, durable, classic luxury appearance
· Teak: tropical hardwood - natural oil content provides inherent moisture resistance. Premium choice for humid climates.
· Walnut: rich dark brown, elegant grain - contemporary and traditional luxury
· Ash: light color, pronounced grain - Scandinavian and modern interiors
· Meranti / Mahogany: reddish-brown, cost-effective - popular in Southeast Asian markets
· Engineered timber (LVL/finger-jointed): dimensionally stable, sustainable use of fast-growing timber - cost-effective alternative to solid hardwood
Aluminum exterior finishes:
· Powder coating: solid RAL/NCS colors, matte or satin. Anti-corrosion, UV-resistant. The most common exterior finish.
· PVDF fluorocarbon: premium weather-resistant finish - 25+ year color and gloss retention. For coastal and extreme climate locations.
· Wood-grain transfer on aluminum: realistic wood texture on the exterior aluminum face - maintains the traditional timber door aesthetic from the street while providing aluminum durability. Available in oak, walnut, teak, mahogany.
· Anodizing: metallic finish - bronze, black, champagne, natural silver - contemporary architecture.
Wood interior finishes:
· Natural oil: matte, enhances grain, easy to spot-repair - the preferred interior finish for premium doors
· UV-cured lacquer: satin or gloss, scratch-resistant - durable for high-traffic doors
· Stain + clear coat: custom stain color to match interior joinery and flooring
· Paint-grade wood: MDF or poplar wood interior face ready for on-site painting to match room decor
Glazing and panel options:
· Full glazed: large IGU (double/triple) for maximum natural light
· Half glazed: glazing in the upper half, solid panel lower half
· Solid (no glazing): full wood + aluminum door leaf - maximum security and privacy
· Side lights and transom windows: fixed aluminum-wood glazed panels flanking or above the door

A: Yes. Aluminum-wood doors can achieve certified fire ratings when specified with fire-rated construction:
· Fire-rated wood core: solid timber core treated with fire-retardant chemicals, or mineral-core fire door construction
· Intumescent seals: fitted into grooves in the aluminum frame and door leaf edge - expand 15–25× when heated, sealing the gap between door and frame
· Fire-rated glazing (if applicable): wire-glass or ceramic glass in fire-rated framing
· Fire-rated hardware: hinges, locks, and closers tested to maintain integrity under fire conditions
Fire ratings achieved:
· GB 12955: Class A (1.5h), Class B (1.0h), Class C (0.5h) fire doors
· BS 476 Part 22 / EN 1634-1: FD30 (30-minute), FD60 (60-minute) - integrity and insulation
· Smoke control: FD30S / FD60S - with cold smoke seals for protected escape routes
Fire test certificates are provided with every fire-rated door. The aluminum cladding does not degrade the fire performance - it protects the wood core during the early stages of fire exposure.

A: · Standard sizes with standard finishes: 20–30 working days
· Custom sizes or special wood species: 30–45 working days
· Fire-rated models: add 10–15 working days for certification-specific manufacturing
· Large project orders (50+ doors): phased delivery, schedule confirmed case-by-case
Production involves two parallel processes: wood door fabrication (timber conditioning → joinery → sanding → finishing) AND aluminum fabrication (extrusion → cutting → coating → assembly). These converge at final assembly (aluminum cladding bonded to wood core). Wood moisture content conditioning (target 8–12%) is critical - insufficient drying causes future movement.
We recommend ordering 8–10 weeks before doors are required on site.

A: Packaging: Aluminum-wood doors are packaged with the highest care due to their value and dual-material nature. Each door is wrapped in PE protective film on both aluminum and wood faces. All four corners are protected with reinforced corner guards. The aluminum edge frame is protected with adhesive foam strips. Doors are shipped vertically in A-frame steel stillages (NEVER flat) with soft strapping. Each stillage is enclosed in a fully-sealed plywood crate with moisture-barrier lining and desiccant packs.
Shipping:
· Domestic: dedicated air-ride suspension truck, door-to-door
· International: FCL sea freight in 40HQ containers with vertical A-frame loading. FOB/CIF terms.
Handling and storage: transport and store vertically. If flat storage is unavoidable, support the door at multiple points along its length (every 600mm) to prevent sagging. Store in a dry, ventilated area. Allow the door to acclimate to the installation environment for 24–48 hours before installation.

A: Installation - combines elements of door installation and aluminum joinery:
① Frame installation: the aluminum-wood door frame is installed in the rough opening using heavy-duty adjustable fixing brackets. Use a laser level to ensure the frame is perfectly plumb in both planes, level at the head, and square (diagonal measurements equal). Secure frame to the wall structure (concrete, brick, or reinforced stud) with expansion anchors or chemical anchors at all fixing points. The aluminum frame is self-finished - no architrave is needed unless specified for aesthetic reasons.
② Gap filling: fill the gap between frame and wall opening with expanding PU foam (low-expansion, door-grade) for thermal insulation and to prevent frame movement. Trim excess foam after curing. Apply external weather sealant (silicone or PU) at the exterior frame-to-wall junction; internal sealant at the interior junction.
③ Door hanging: the door arrives pre-hung in the frame (factory-hung and adjusted) or as a slab (door leaf only) for on-site hanging. For factory-hung: simply install the complete frame unit. For slab: mount hinges on the frame, hang the door, and adjust.
④ Hinge adjustment: aluminum-wood doors use heavy-duty stainless steel butt hinges or 3D adjustable concealed hinges. Adjust for:
- Height: even gap at the head (3–4mm)
- Side: even gap on hinge and lock stile (3–4mm)
- Compression: correct gasket compression (visible contact line on the gasket, not crushed flat)
⑤ Hardware installation: install lock body, cylinder, handle, strike plate, and any additional hardware (door closer, floor stop, viewer). Test all functions: locking, unlocking, handle operation, snib, deadbolt.
⑥ Weather seal check: close the door and inspect the weather seals visually from inside and outside. No light should be visible through the seals - test with a flashlight in a darkened room. Adjust hinge compression if gaps are present.
⑦ Threshold installation: install the aluminum or stainless steel threshold at the door base. Ensure it is level and sealed to the floor. The door bottom seal (drop-down or fixed) must engage the threshold evenly across its full width.
⑧ Glazing inspection (if applicable): check the glazing beads and gaskets are fully seated. Clean the glass with a non-abrasive glass cleaner.
⑨ Touch-up: inspect for any scratches or marks from installation. Touch up minor aluminum scratches with matching touch-up paint (provided). Clean wood surfaces with a dry microfiber cloth.
We provide a comprehensive installation manual and offer on-site supervision for the first door installation on large projects.
