Manufactured by Guangdong Dejiyoupin Doors and Windows Co., Ltd. from primary aviation-grade 6063-T5 aluminum alloy, our entry door series seamlessly unites grand aesthetics with reinforced structural rigidity. Custom designed for coastal salt-mist resilience, seismic structural displacement, and thermal isolation across South American architectural standards.
Contemporary Pivot An impressive large-format pivot entrance door engineered with German heavy-duty concealed ground pivots, tempered laminated Low-E safety glass, and 360-degree perimeter sealing.
Grand Entrance High-load pivot door system built for luxury villas and upscale commercial facades. Delivers effortless opening dynamics despite leaf weights exceeding 350 kg, featuring seamless multi-point locking.
Thermal Isolation Equipped with multi-cavity PA66 GF25 thermal barrier strips to eliminate thermal bridging. Ideal for regions with severe day-night temperature swings like the Andean highlands and Southern Cone.
Minimalist Flush Features precision concealed 3D-adjustable hinges that remain hidden when closed, offering ultra-clean architectural lines combined with patented Four-Side Six-Point anti-theft security locking.
Every entry door system manufactured by Guangdong Dejiyoupin Doors and Windows Co., Ltd. undergoes calibrated batch testing to ensure compliance with strict structural, acoustic, and thermal envelope standards.

With 25+ years of specialized fenestration manufacturing, our 180,000 m² Foshan facility integrates automated CNC precision machining with stringent ISO 9001 certified production controls.
Our proprietary locking systems, including the Four-Side Six-Point locking invention patent, physically secure the sash to the frame along all four boundaries to deliver industrial-strength burglary prevention.
All entrance doors are covered with protective laser films, wrapped in impact-absorbing bubble lining, corner-shielded, and crated in heavy-duty fumigated wooden cases configured for long container transit.
Every commercial or luxury residential opening is modeled via BIM / CAD shop drawings, verifying wall opening tolerances, threshold heights, drainage angles, and structural anchor spacing before extrusion.
Guangdong Dejiyoupin Doors and Windows Co., Ltd. applies comprehensive quality checkpoints across every phase of production. We ensure each exterior door delivers lasting operation whether placed on humid Atlantic beaches or high-altitude Andean plateaus.
Every entry door frame and leaf is dry-fitted at the factory to calibrate smooth hinge pivot action, lock latching, and uniform gasket compression before crating.
Integrated concealed weep-hole drain systems with one-way wind valves stop driving storm water and sea-breeze moisture backflow during hurricane events.
Compatible with biometric fingerprint readers, smart facial recognition keypads, electronic rim mortises, and unified smart home management systems.
