For projects that demand a precise 29 x 80 interior door, DERCHI’s WP-54 model delivers a factory-built aluminum glass swing door that fits right out of the crate. Instead of modifying stock doors on site, you receive a door manufactured to your exact opening dimensions—saving labor and ensuring a cleaner finish.
- Made to measure for 29 x 80 inch openings (width 350–850 mm, height 400–2400 mm)
- 54 mm slim aluminum frame with a modern, light-filled profile
- Single 8 mm tempered glass or double‑pane insulated unit
- Direct B2B supply with project consultation and shop drawing review
Product Details
The WP-54 door is built on 6063‑T5 aluminum extrusions: the frame profile is 1.4 mm thick, the door leaf 2.0 mm, giving it the stiffness to handle daily traffic in offices and apartments. A continuous EPDM rubber seal runs around the perimeter, cutting drafts and noise. Glass is factory‑installed—either a monolithic 8 mm tempered pane or a 5 mm + 12A + 5 mm double‑glazed unit—so tight tolerances are maintained and quality stays consistent unit after unit.
What distinguishes this door is the 54 mm frame width, which creates an ultra‑narrow sightline. This lets in more daylight than traditional wood or hollow metal doors and contributes to a clean, contemporary look without sacrificing strength. Every door is assembled to the specified 29 x 80 size (approximately 736.6 × 2032 mm), so there’s no need for field cutting or shimming.
Product Features
True custom fit: Each door is cut and assembled to the 29 x 80 specification, so it slots straight into non-standard openings—no trimming, no gaps.
Slim profile, maximum light: The 54 mm frame keeps sightlines thin, making interiors feel larger and brighter while supporting the door‑leaf weight.
Safe and configurable glazing: Pick from 8 mm tempered or insulated glass. Frosted, tinted, and Low‑E coatings are available to manage privacy and solar gain.
Durable aluminum structure: 6063‑T5 alloy and a 2.0 mm leaf thickness resist warping, even in busy corridors.
Performance data you can reference: Tested values include U‑factor 0.39 and sound insulation 37 dB (with standard glass). Verify these against your chosen configuration and installation.
Factory‑direct support: DERCHI’s team handles everything from shop drawings to quality inspection, helping contractors avoid middleman delays.
Customizable Styles
Glass selection: Single 8 mm tempered or dual‑pane 5+12A+5 insulated glass. Options include clear, frosted, tinted, and Low‑E coatings for added thermal control.
Frame finish: Standard powder coating in black, white, or grey. Wood‑grain, anodized, and custom RAL colors available on project orders.
Exact sizing: Produced to the 29 x 80 dimension within the model’s width range of 350–850 mm and height range of 400–2400 mm, subject to technical review.
Handing and swing: Choose left or right handing, inward or outward opening to suit your floor plan.
Project‑level branding: For hotel chains or residential schemes, DERCHI can incorporate client logos or specific finish packages—discuss during quotation.
Hardware Accessories
DERCHI lever handle: An ergonomic aluminum handle available in brushed, black, and other finishes to match the door’s slim aesthetic.
3D adjustable hinges: DERCHI‑branded hinges allow installers to fine‑tune door alignment after hanging, reducing call‑backs.
Lock preparation: Door edge prepped for standard mortise or tubular locks; specify lock type and backset to align with local hardware standards.
EPDM sealing: Continuous gasket around the frame improves air tightness and dampens sound, contributing to indoor comfort.
Concealed closer option: The WP‑54 can be adapted for concealed door closers in semi‑public areas—confirm technical feasibility with DERCHI beforehand.

Advantages
Decades of manufacturing experience: Since 1999, DERCHI has supplied aluminum windows and doors worldwide, offering a stable supply base for repeat interior door orders.
Capacity to handle volume: A 180,000 m² factory and 300,000 m² annual capacity mean we can schedule large runs of custom‑sized doors without extended lead times.
True factory customization: As a manufacturer controlling extrusion and assembly, we can tailor each 29 x 80 door to exact specs—no middlemen, no markups.
Recognized test certifications: The WP‑54 has passed NFRC, CE, and AS2047 testing. Current certificates for your configuration are available on request to support local code approvals.
End‑to‑end project service: A dedicated contact guides you from initial drawings and samples through production, QC inspection, and logistics.
Application Scenarios
Apartment: In older buildings with odd‑sized rough openings, a factory‑made 29 x 80 aluminum glass door replaces dark solid doors, bringing daylight into hallways and bathrooms.
Home Office: The WP‑54 can separate a workspace from the living area while preserving an open feel; its 37 dB sound reduction helps contain conversations and phone calls.
Hotel: Spec this door across guest floors to ensure every unit matches the brand standard. DERCHI’s batch production delivers identical fit and finish, simplifying installation schedules.
Office Building: When meeting rooms or private offices have non‑standard doorways, ordering pre‑hung doors in this custom size eliminates drywall patching and on‑site carpentry.
Outdoor: A covered balcony or semi‑enclosed courtyard can use this door if exposure to driving rain is limited. Check the 3 kPa wind rating and 300 Pa water tightness against local weather.
Residential Building: Multi‑unit projects benefit from a single custom size across all units, reducing material waste and labor while the narrow frame elevates the interior design.
Exterior: Sheltered passageways, such as covered breezeways, may suit the WP‑54 as a lightweight partition. Confirm corrosion‑resistant finish and additional weatherstripping for lasting performance.
Villa: In luxury homes, the 54 mm frame can be used for floor‑to‑ceiling internal glazing that visually expands rooms while defining separate zones.
