Explore our primary factory-engineered architectural door series, engineered from structural 6063-T5 virgin alloy profiles with precision hardware, acoustic EPDM multi-chamber gaskets, and European safety tempered glazing.
Guangdong Dejiyoupin Doors and Windows Co., Ltd. (DERCHI) stands among China's Top 10 door and window brands. Operating from the world's metal capital in Foshan, we merge heavy industrial automation with bespoke architectural craftsmanship.
Unlike regional assemblers reliant on generic commercial extrusions, we maintain rigorous chemical composition audits for every ingot melted. Our 6063-T5 and 6060-T6 primary structural billet alloys demonstrate yield tensile strength exceeding 160 MPa, ensuring tall interior frames resist mechanical bowing, torsional twist, and latch misalignment over decades of continuous high-frequency cycling.
Fully compliant with international performance criteria, tested for CE, ISO9001, AS2047, and UL fire classifications. Certified acoustic insulation metrics verified through independent NATA-accredited laboratories.
Every commercial schedule receives dedicated CAD shop drawings, glass calculation reports, and BIM Revit files for clash-detection. Custom widths, structural floor-to-ceiling heights up to 3.8 meters without transom bars.
Dedicated project managers assigned to your international working hours across North America, Latin America, Oceania, and Europe. Rapid technical revisions, 24-hour turnaround quotes, and live digital factory audits.
Multi-layered protective PE films, molded corner caps, bubble buffer, and moisture-barrier shrink wraps encased within fumigated solid plywood crates ensure zero transit flex or glass shatter on oceanic voyages.
The contemporary commercial and luxury residential sector is witnessing a paradigm shift away from traditional hollow-core wooden slabs towards minimalist aluminium systems with integrated smart acoustics.
Demands for visual transparency have pushed frame stiles down to 16mm-25mm visible borders. Using cold-drawn T6 structural alloys, our minimalist French casement internal doors support massive architectural glass panes while maximizing natural daylight illumination between partitioned living zones.
Traditional butt hinges are being superseded by heavy-duty bottom hydraulic floor-springs and ceiling-mounted needle-bearing pivot hinges. These allow balanced swinging action for panels weighing up to 250kg, featuring 360-degree rotation or soft-closing hold-open detents at 90 degrees.
Modern working-from-home demands have made acoustic privacy a primary specification. Internal doors are increasingly configured with multi-chamber EPDM co-extruded perimeter seals, automatic drop-down bottom sweeps, and Italian magnetic locks that retract completely when open for silent operation.
Where light transfer is essential but optical privacy is required—such as executive meeting rooms, ensuites, and master baths—specifiers are favoring Moru (reeded) glass, acoustic PVB laminates, or electrically switchable polymer-dispersed liquid crystal (PDLC) privacy panels.
Traditional glossy powder coatings have been replaced by architectural ultra-matt, sandblasted metallic champagne, bronze anodized, and deep basalt grey finishes. These nanotech coatings prevent finger smudging, oil staining, and surface micro-scratches from rings or keys.
Universal design codes mandate smooth floor transitions without trip hazards. Modern aluminium interior bi-fold and sliding systems utilize top-hung load-bearing trolleys or flush-recessed subfloor tracks with stainless steel bearings, creating seamless continuity across room finishes.
For real estate conglomerates, hospitality developers, and building material distributors, international procurement dynamics are evolving rapidly. Here is where the commercial advantage lies.
Leading procurement teams are discarding multi-vendor fragmented models. By contracting with a unified manufacturer capable of delivering internal glazed partitions, heavy thermal exterior doors, garage gates, and windows, developers slash ocean container freight by up to 34% and eliminate site finish color mismatches.
Commercial projects targeting LEED Platinum, BREEAM, or Green Star certifications increasingly mandate verified Environmental Product Declarations (EPDs). Sourcing aluminium produced with hydroelectric smelting power rather than coal-fired grids reduces product carbon footprints by up to 65%.
On-site mortising for digital biometric locks, hidden power conduits, magnetic reed switches, and keypad escutcheons creates high labor costs and defect risks. Modern B2B buyers now mandate 100% factory pre-milling and wire channel integration directly in shop drawings.
A direct technical comparison across common architectural interior door substrates under high-traffic, multi-family, hospitality, and residential usage parameters.

Standard fabrication spans 25 to 35 business days following formal sign-off on shop drawings and glass schedules. Expedited 18-day cycles are available for repeat developer schedules utilizing in-stock mill finish profiles with rapid RAL powder coating.
Our direct factory model supports flexible procurement: MOQ starts at 1 full villa set or 10 units for bespoke openings. For large-scale multi-family developments or commercial hospitality projects, volume tiers unlock optimized full container load (FCL) pricing.
Yes. Unlike wooden doors that swell, absorb mold, or suffer surface veneer peeling, 6063-T5 aluminum with fluorocarbon or 20-micron anodized coating is totally non-porous. Integrated bottom drainage slots and waterproof EPDM gaskets ensure permanent hygiene and zero rust.
All glazing complies with EN 12150 (CE), ANSI Z97.1 / SGCC, and AS/NZS 2208. Configurations include 8mm/10mm monolithic toughened glass, 5mm+0.76PVB+5mm acoustic laminated glass, reeded/fluted patterns, or dual insulated units filled with Argon gas for acoustic targets up to 42 dB.
Yes. Our engineering department of 40+ draftspersons produces complete 2D elevation/section CAD drawings and 3D Revit BIM families free of charge prior to cutting. This guarantees seamless clash detection with structural openings and finished flooring heights.
We partner with premier hardware manufacturers including HOPPE, Roto Frank, Sobinco, Dormakaba, and specialized Italian magnetic latch suppliers (AGB). Custom commercial master-keying or electronic access systems can be pre-mortised at the factory.
Every door panel receives static-free surface film, closed-cell corner guards, high-density bubble wrap, and is crated in IPPC-certified fumigated structural plywood boxes. Openable crates feature internal strapping to prevent vibration and panel scuffing.
We regularly ship under FOB Foshan/Shenzhen/Guangzhou, CIF, CFR, or DDP (Delivered Duty Paid to client warehouse/jobsite). Major global destinations include Los Angeles, New York, Santos, Valparaíso, Callao, Sydney, Melbourne, Rotterdam, and Dubai.
Every shipment is accompanied by sequential numbered piece-marks corresponding directly to floor-plan door schedules, illustrated step-by-step manuals, and high-definition video walkthroughs. Live video technical guidance is provided during key installation stages.
DERCHI provides a comprehensive 10-Year Warranty on structural profile integrity and frame squareness, a 5-Year Warranty on AkzoNobel/Qualicoat powder coating against chalking and color fading, and a 3-Year Warranty on mechanical hardware components.
