R&D Innovation Horizon
Engineering Advancements in Architectural Partition Design
From electromagnetic levitation to dynamically switchable privacy glass, discover the core technical disciplines revolutionizing interior space management.
Concealed Magnetic Levitation (Maglev) Drive
Traditional floor tracks gather dust, create trip hazards, and impede robotic vacuum cleaners. Our latest partition series incorporates overhead magnetic levitation tracks that suspend the entire sash with zero mechanical contact friction. Operating at noise levels under 28 decibels, Maglev partition sliders offer silent, effortless glide motions combined with push-to-activate electric motors, remote smartphone integration, and radar collision safety detection.
Frictionless GlidingIntegrated Smart PDLC Switchable Glass
Liquid crystal Polymer Dispersed Liquid Crystal (PDLC) technology is embedded within our double-glazed aluminum partition leaves. Operating via low-voltage dry contacts concealed within internal pivot hinges or sliding drag-chains, the glass instantly switches from crystal-clear transparency to frosted visual opacity in under 0.05 seconds, delivering instant privacy for boardrooms, clinic consultation suites, or residential bedrooms without mechanical blinds.
Dynamic ElectrochromicsMicro-Sightline Architectural Profiles
Structural engineering breakthroughs allow DERCHI to reduce vertical meeting stile interlock sightlines down to an industry-leading 16mm. By integrating internal high-tensile carbon-steel core reinforcements into the extruded aluminum chamber, these micro-slim frames achieve wind load structural deflection resistance compliant with Class C5 (EN 12210) while delivering unmatched panoramic transparency.

Frequently Asked Questions for Project Specifiers & Importers
Comprehensive engineering clarity on international certifications, structural sizing constraints, logistical export packaging, and custom project execution.
What specific testing standards are mandated for CE Certification of aluminum partition doors?
Under European harmonized standard EN 14351-1:2006+A2:2016, CE marking for pedestrian doorsets verifies mechanical strength, safe operating forces, air permeability (EN 12207), water tightness (EN 12208), acoustic performance (EN ISO 717-1), and dangerous substance release limitations. For partition systems demarcating interior boundary enclosures or high-traffic commercial spaces, our products undergo independent Notified Body (NB) initial type testing (ITT) and routine Factory Production Control (FPC) testing. Every containerized order is accompanied by a compliant Declaration of Performance (DoP) bearing our CE manufacturer identification, ensuring seamless customs clearance across EU member states and partner jurisdictions.
How does an aluminum frame partition system compare acoustically against traditional drywall or frameless glass?
Frameless 10mm or 12mm glass partitions suffer from severe sound leakage through unsealed glass-to-glass perimeter joints and bottom floor gaps, rarely achieving a weighted sound reduction index (Rw) beyond 28–30 dB. Conversely, standard drywall construction provides acoustic opacity but eliminates daylight transmission and visual cohesion. DERCHI double-glazed aluminum partition door systems bridge this performance gap: utilizing multi-cavity insulated aluminum profiles, dual perimeter EPDM compression seals, and asymmetric acoustic laminated glass (such as 6mm + 0.76mm acoustic PVB + 8mm toughened), our partitions consistently achieve lab-certified acoustic values from Rw 38 dB up to Rw 46 dB, isolating speech and operational machinery noise while maximizing natural ambient light.
What aluminum extrusion alloys and wall thicknesses are used to prevent tall partitions from bowing?
We exclusively formulate profiles from primary 6063-T5, 6063-T6, and 6060-T66 virgin aluminum billets, completely omitting unrefined scrap remelts. For partition wall systems reaching heights between 2,800mm and 3,800mm, the structural vertical mullions and load-bearing door stiles are extruded with heavy wall thicknesses ranging between 2.0mm and 3.0mm. Furthermore, our engineering team calculates the Area Moment of Inertia (Ix and Iy values) for every custom shop drawing to guarantee that structural deflection under human live loads and indoor atmospheric pressures does not exceed L/250 or 15mm, preserving hinge alignment and smooth roller operation across decades of active service.
Can DERCHI partition systems accommodate integrated access control and automatic electric drop seals?
Yes. Our CNC milling centers execute factory-cut pockets for concealed mortise locks, electric magnetic strikes, RFID badge card readers, biometric smart handles, and hidden door closers (such as Dorma or Geze concealed units). For acoustic sliding or hinged partitions, we incorporate concealed bottom mechanical drop seals; when the door leaf engages the closed position against the jamb, an internal stainless actuator plunges a heavy-duty silicone gasket flush against finished timber or stone floor surfaces, hermetically sealing the bottom gap without requiring a raised floor threshold.
How does your Foshan facility handle custom shop drawings, BIM coordination, and job site variances?
We operate a dedicated project technical group consisting of 45+ specialized facade and interior fenestration engineers. Upon receiving your architectural floor plans, ceiling reflection schedules, and wall elevations, we generate complete CAD shop drawings containing exact section profiles, anchoring details, and glazing schedules within 24 to 48 hours. We also furnish native Autodesk Revit (.RFA) and IFC parametric BIM models for clash detection. To mitigate real-world building slab deflections and out-of-plumb walls, our outer receiver sub-frames include ±15mm lateral and vertical telescoping adjustment compensators, guaranteeing effortless site installation.
What export packaging protocols ensure oversized glass partition panels survive maritime transport?
Export sea freight subjects fenestration components to prolonged vibration, humidity, and inertial shock. DERCHI employs a five-layer industrial export packing standard: (1) peel-off protective surface film over all finished aluminum faces; (2) shock-absorbing high-density polyethylene (EPE) foam corner guards; (3) fully enclosed multi-layer bubble wrap; (4) waterproof plastic vapor stretch membrane; and (5) ISPM-15 certified heat-treated solid timber or heavy plywood crates with internal structural timber bracing and desiccants. Crates are loaded and lashed directly inside dry containers using heavy-duty ratchet tie-downs to ensure zero cargo shifting during long-haul sea passages.
What is your typical production lead time, Minimum Order Quantity (MOQ), and warranty policy?
Our standard production cycle for customized partition door systems is 25 to 35 business days following final sign-off of CAD production shop drawings and glass approval. For standard colors (such as matte black, architectural white, and bronze anodized), rapid-turnaround fabrication can be achieved in 18 days. We maintain a flexible MOQ policy: commercial projects and villa developments qualify starting from single custom house lots or 50 m², up to multi-thousand square meter institutional orders. All aluminum extrusions and structural finishes carry a 10-year manufacturer warranty, with operational hardware backed by a 5-year replacement guarantee.
Can your partition doors be configured for Vastu or Feng Shui spatial alignment?
Yes. Custom dimensional flexibility is a core pillar of our manufacturing process. We regularly work with architects and clients in South Asia and Southeast Asia who require specific door opening clearances, handedness, and leaf ratios adhering to Vastu Shastra or Feng Shui spatial traditions. Our engineering software calculates exact glass and frame cutting sizes to the millimeter to fulfill specific auspicious height-to-width dimensional proportions while maintaining full structural and acoustic compliance.
