Stack Door Core
Our flagship multi-track architectural stacking door featuring ultra-slim sightlines, flush floor thresholds, and heavy-duty tandem bogie rollers for panoramic glass expanses.
Thermal Shield Wrap
Heavy-duty reflective thermal shielding wrap delivering high radiative insulation and perimeter barrier protection during cross-ocean container freight and on-site building installation.
High Security Entry
Cast aluminum and multi-chamber composite soundproof entrance door engineered with multi-point anti-burglary locks and automated biometric smart entry integrations.
Aluminium stack doors (multi-slide stacker systems) represent the zenith of architectural fenestration, bridging structural stability with maximum visible glass ratios. Unlike conventional two-panel sliding doors or accordion bi-folds, stacking doors slide smoothly along tandem or triple tracks, parking neatly behind a fixed jamb to offer up to 75% unobstructed clear openings.
At our 180,000㎡ industrial manufacturing center in Foshan, China, DERCHI manufactures stack door profiles utilizing high-purity primary ingot 6063-T6 aluminum. Utilizing thermal break polyamide bars (PA66GF25 reinforced with 25% glass fiber), our systems interrupt internal-to-external thermal bridging, lowering overall thermal transmittance (U-factors) to as low as 1.4 W/m²·K when paired with argon-filled, double-glazed Low-E insulated glass units (IGU).
Structural reliability hinges on multi-wheel stainless steel tandem rollers capable of holding up to 400kg per movable leaf. Equipped with concealed water weep drainage channels and marine-grade anodized or PVDF fluorocarbon coatings, our stacking door configurations endure 3,000 hours of continuous salt-spray testing without oxidization.
Eliminates condensation and drastically reduces HVAC heat load across tropical and extreme climate zones.
Certified to withstand serviceability and ultimate wind pressures up to 4500Pa, ideal for typhoon-prone coastal corridors.
Dual-row precision sealed bearings ensure effortless one-finger glide operation across 100,000 opening cycles.

International real estate developers, commercial contractors, and facade consultants are actively pivoting their sourcing methodologies. Understanding these shifts provides strategic leverage when negotiating with Chinese manufacturing partners.
Stack doors are transitioning from manual hardware to concealed brushless DC belt-drive actuators and magnetic levitation motors. Next-generation systems integrate directly into KNX, Zigbee, and BACnet automation networks, enabling smartphone, sensor-based rain triggers, and voice-command operation for super-sized multi-leaf configurations.
Architects worldwide increasingly demand ultra-narrow interlocks with sightlines measuring under 20mm. Procurement requirements emphasize fully recessed floor tracks that eliminate tripping hazards and comply with international ADA barrier-free access codes while incorporating integrated hidden perimeter drainage troughs.
Global procurement teams prioritize Tier-1 Chinese suppliers verified under ISO 14025 Environmental Product Declarations (EPD). Utilizing hydro-powered recycled low-carbon aluminum billets reduces embodied emissions by up to 60%, matching European CBAM and LEED certification mandates for institutional projects.
Operating from the global fenestration manufacturing capital of Foshan, Guangdong Dejiyoupin Doors and Windows Co., Ltd. brings 25+ years of OEM/ODM fabrication authority, recognized among China's Top 10 architectural brands.
Our centralized manufacturing base houses automated CNC profile machining centers, German dual-component corner crimping equipment, and high-precision glass assembly lines staffed by over 600 specialized workers.
DERCHI systems are independently tested to Australia's AS 2047, European CE, ISO 9001, and UL fire-rating standards, guaranteeing trouble-free municipal building approvals across Southeast Asia, North America, and the Middle East.
Our in-house facade engineers provide complimentary CAD shop drawings, wind load deflection calculations, and structural glass analysis directly matched to your architectural schedules prior to extrusion cutting.
Strategically located near major Pearl River Delta ports (Shenzhen and Guangzhou). English-fluent project managers provide real-time coordination, rigorous seaworthy plywood crating, and complete job-site installation manuals.
Clear, technical insights to streamline risk evaluation, logistics planning, and manufacturing verification when sourcing stack doors from China.
