Patented multi-point locking mechanisms providing superior forced-entry deterrence meeting EN burglary resistance standards.
Multi-cavity profiles and composite sound-dampening laminated glazing achieving sound insulation up to Rw 42 dB.
Polyamide thermal breaks and warm-edge double or triple argon-filled glazing configured to achieve demanding Uw targets.
Fabricated across 168 automated manufacturing steps with 38 separate dimensional and weather-tightness checkpoints.
By combining over 80 dedicated R&D personnel with advanced CNC fabrication, Guangdong Dejiyoupin Doors and Windows Co., Ltd. delivers zero-compromise architectural hardware and system performance.
Our proprietary glass self-adaptive adjustment mechanism absorbs structural deflection, seismic stress, and severe wind pressure without causing perimeter seal failure or glass micro-cracking.
Invented and patented by our engineering team (ZL201610053534.X), this mechanism simultaneously engages six heavy-duty anchoring points on all four frame boundaries, providing airtight perimeter sealing and superior anti-theft security.
Certified to the highest green building material tiers and fully compliant with European EN 14351-1 testing standards, verifying reliable thermal resistance, air permeability, and low embodied carbon footprint.
Built on precision tooling and premium hardware, each product line is tailored to meet specific European structural, acoustic, and thermal performance specifications.
Heavy-duty bifold system delivering seamless indoor-outdoor transitions with flush threshold detailing and stainless steel multi-wheel bottom rolling assemblies.
Motorised or manual architectural sliding door supporting panel weights up to 400 kg with whisper-quiet linear drive mechanisms and concealed drainage channels.
Engineered for high wind-pressure coastal installations, featuring reinforced interlocks, dual EPDM weather seals, and smooth lift-and-slide operation.
Contemporary grand entrance door system equipped with concealed hydraulic floor dampers, biometric access compatibility, and thermal profile insulation.
Ultra-narrow 20mm visual sightline interlock designed for panoramic views in luxury contemporary residential villas and high-end penthouses.
Concealed-hardware interior sliding mechanism where mounting rails and running carriages remain completely hidden, producing an elegant floating aesthetic.
