Manufactured by Guangdong Dejiyoupin Doors and Windows Co., Ltd. (DERCHI). Every assembly is customized to structural mill tolerances, offering thermal performance, acoustic isolation, and architectural refinement for premier commercial and residential developments.
Commercial-spec multi-track lift-sliding system engineered with heavy-gauge 6063-T6 aluminum profiles, structural interlocks, and flush acoustic seals for high-span transitions.
Precision engineered acoustic casement and partition framing featuring multi-cavity thermal profiles, EPDM pressure-injected gaskets, and architectural black PVDF coating.
Engineered for luxury hospitality suites, this system integrates PA66 nylon thermal barriers with toughened dual glazing for refined interior room divisions and ensuite zoning.
Ultra-premium hybrid composite system pairing structural exterior aluminum with solid Russian larch interiors, bridging biophilic tactile warmth with high mechanical rigidity.
Bespoke architectural replacement and retrofit framing engineered for silent closure, seamless interior wall matching, and superior structural deflection resistance under ASTM guidelines.
Modular interior office storefront partition and conference sliding entrance, configured with overhead concealed suspension tracks and slim-line transoms for open sightlines.
Ultra-rigid aluminum double-leaf door system featuring internal steel-reinforced subframes, multi-point locking mortises, and heavy-gauge hinges designed for major residential master suites.
Panoramic internal space-divider folding door engineered with bottom-loaded stainless steel carrier guide rollers, top stabilization hinges, and 95% unobstructed open area.
In contemporary high-density luxury developments, hospitality resorts, and corporate campuses, the internal sliding door has migrated from a passive physical partition into an active architectural acoustic control element. Modern internal sliding systems require rigorous mechanical calibration to deliver structural rigidity, micro-fine sightlines, and whisper-silent travel across high operating cycles.
The engineering frontier of interior fenestration is dominated by 6063-T6 architectural alloy extrusion geometries that permit vertical sash heights exceeding 3,200 mm with interlock profile widths as narrow as 16 mm. Achieving this structural equilibrium requires finite-element wind and deflection calculations, even for interior partitions subject to HVAC pressure variations, acoustic differential loads, and continuous human operation.
Structural minimalism is now an architectural requisite. Modern profiles leverage multi-cavity internal reinforcing webs, allowing visible stiles to contract to 16mm–22mm while supporting pane weights up to 250kg without out-of-plane torsional warping.
Eliminating exposed ceiling tracks and bottom threshold channels, ghost sliding hardware utilizes recessed ceiling tracks or top chassis assemblies anchored inside wall cavities, creating seamless uninterrupted flooring transitions.
Interior zoning demands effective acoustic decibel mitigation. Advanced interior sliding doors integrate dual-direction hydraulic damping pistons with self-lubricating POM polymer wheels, reducing operational sound below 28 decibels.
High-touch internal doors face aggressive scratch hazards. The transition from basic liquid paint to architectural fluorocarbon PVDF, 25-micron anodizing, and tactile electro-deposition creates tactile luxury and anti-fingerprint surfaces.
Modern executive boardrooms and luxury penthouse master bathrooms incorporate internal sliding panels laminated with Polymer Dispersed Liquid Crystal (PDLC) interlayer film, transforming from optically transparent to 99% opaque in <100ms.
Magnetic levitation (Maglev) drive motors eliminate gearboxes, toothed belts, and friction-induced wear. The door sash travels effortlessly on a brushless magnetic field, ideal for barrier-free healthcare, luxury suites, and smart homes.

Global architectural procurement heads, real estate developers, and fenestration importers are shifting away from fragmented regional sourcing. Below are the macro trends reshaping contract procurement out of China.
Developers are eliminating the overhead of managing separate vendors for exterior entries, internal sliding pocket doors, bathroom glazed partitions, and garage gates. Single-source manufacturing from an accountable 180,000 m² factory cuts freight container underutilization, harmonizes finish shades, and mitigates cross-trade installation conflicts.
Specifiers no longer accept vague catalog cut-sheets. B2B contracts now demand millimeter-exact CAD shop drawings, IFC/Revit BIM models, and comprehensive threshold extrusion sections prior to production kickoff. This prevents on-site spatial conflicts between recessed tracks and finished ceiling plenums.
With global green building benchmarks like LEED v4.1, BREEAM, and Green Star gaining mandatory status across international developments, Chinese tier-1 manufacturers are deploying certified low-carbon hydroelectric-smelted aluminium billets, delivering documented Environmental Product Declarations (EPDs).
Operating out of China's world-renowned manufacturing epicenter in Foshan, Guangdong, Guangdong Dejiyoupin Doors and Windows Co., Ltd. (DERCHI) ranks among the elite Top-10 brand manufacturers in China. Our integrated enterprise encompasses more than 600 full-time specialists dedicated to advanced fenestration research, profile die extrusion, precision CNC fabrication, and comprehensive QA testing.
Whether fulfilling hotel tower interior sliding door schedules in North America, high-end villa master suites in the Middle East, or resilient coastal residential projects across Africa and Australia, we deliver one single accountable source for custom aluminium, cast aluminium, glazed, and high-security entry assemblies.
Direct engineering responses on international shipping, lead times, structural tolerances, glass certification, and field installation guidance.
For custom manufactured orders with bespoke shop drawings, typical factory manufacturing time is 25 to 35 calendar days following client approval of CAD submittals and deposit clearance. Standard stock profile finishes (matte black, architectural bronze, white) can expedite in 20 days, whereas custom RAL fluorocarbon or woodgrain finishes require the full 35-day cycle to allow proper multi-stage curing and adhesion testing.
Yes. We engineer complete pocket sliding cassette systems including pre-machined extruded aluminum ceiling track housings with integrated drywall return flanges. These allow the track to be set fully flush inside false ceiling plenums before plasterboard and paint application. We supply matching magnetic service panels to ensure overhead carriages and soft-close pistons remain accessible for lifetime maintenance without ceiling demolition.
All architectural glass panels supplied by DERCHI are fully certified for international building code approvals. Tempered and laminated glass options carry CE (EN 12150 & EN 14449), North American SGCC (ANSI Z97.1 / 16 CFR 1201), and Australian Standards AS/NZS 2208 certifications. Test reports, mill sheets, and batch certificates are supplied in our standard documentation package for project consultant sign-off.
Every frame and sash element receives high-density PE scratch-resistant tape, wrapped in EPE pearl shock cotton, and corner-capped with high-impact ABS guards. Entire assemblies are packed into non-fumigation ISPM-15 compliant solid plywood crates braced with steel banding. For complete container loads (FCL), crates are strapped with pneumatic dunnage airbags to eliminate maritime transit vibration and port handling shock.
Because we operate flexible intelligent CNC production lines in tandem with high-volume extrusion processing, our typical MOQ is 1 complete set or single villa package for custom residential commissions, and 10 to 500+ units for multi-family residential towers or hotel projects. We welcome prototype mock-up orders for architectural review prior to full schedule container release.
Every door schedule is delivered with numbered exploded-assembly shop drawings, component location schematics, and bilingual video manuals detailing floor track anchoring, level calibration, and soft-stop tensioning. Our English-speaking fenestration engineers provide remote technical guidance via real-time video conferencing to ensure contractor crews execute flawless site installation.
