Heavy-duty, motorized, and ultra-slim architectural sliding door systems engineered for typhoon-level wind resistance, low U-values, and large structural openings across Asia.
Guangdong Dejiyoupin Doors and Windows Co., Ltd. supplies verified sliding door systems to international developers, façade consultants, and general contractors. Engineered in Foshan with virgin 6063-T5/T6 aluminum, multi-chamber thermal breaks, and heavy-duty stainless steel running gear.
Motorized & Automated Integrated smart-sensor automated drive mechanism designed for mega-scale openings in penthouses, luxury villas, and high-traffic hotel lobbies. Delivers barrier-free flush thresholds with zero tripping hazard.
Thermal Break Heavy-Duty Engineered for extreme coastal weather conditions, this system features multi-cavity thermal break profiles, high-performance PA66 insulation strips, and multi-point locking. Rated for severe monsoon and typhoon zones.
Minimalist Narrow Stile Minimalist architectural styling featuring ultra-narrow 16mm-20mm vertical sightlines. Maximizes natural illumination and panoramic views without compromising wind resistance or structural load ratings.
Concealed Track System Patented top-hung invisible sliding hardware completely conceals the track mechanism behind the door leaf. Engineered with dual-direction hydraulic soft dampers for silent, smooth, and floating operation.
Every sliding door unit manufactured by Guangdong Dejiyoupin Doors and Windows Co., Ltd. is custom fabricated to structural calculations verified by certified architectural façade engineers.

Our stepped track profile incorporates invisible drainage channels with internal gravity flap valves, completely preventing rainwater back-drafting during severe tropical storms.
Patented multi-point locking mechanisms engage into heavy-duty stainless steel keepers on all perimeter edges, delivering anti-burglary security and uniform weather compression.
High-load stainless steel rollers feature dual sealed ball bearings rated for 200,000 continuous opening cycles, providing smooth and effortless sliding even with 450kg leaves.
Our sliding doors use thick-walled virgin 6063-T6 aluminum alloys reinforced with internal structural steel or high-moment aluminum stiffeners at the vertical interlocks. Combined with continuous EPDM multi-fin weatherseals and laminated impact-resistant glass, our systems resist design wind pressures up to 4500 Pa.
Standard custom orders require 25 to 35 business days following final approval of technical shop drawings and color finish confirmation. Rapid-track scheduling is available for large phased hospitality developments and multi-tower residential projects.
Yes. Our in-house engineering team provides complete technical calculation reports, including wind deflection analysis, U-value thermal models, glass stress calculations, and anchor fixing diagrams required for municipal building approvals across Southeast Asia, East Asia, and the Middle East.
