Discover our comprehensive collection of precision-extruded aluminum double swing doors, commercial entrance portals, and high-performance architectural systems built to exceed global standards.
Modern architectural trends demand wider structural spans, narrower visible sightlines, and uncompromising thermal efficiency. Guangdong Dejiyoupin Doors and Windows Co., Ltd. (DERCHI) stands at the pinnacle of fenestration manufacturing, delivering precision-machined aluminium double swing doors designed for high-end residential estates, commercial headquarters, and hospitality gateways worldwide.
We exclusively utilize virgin 6063-T6 aerospace-grade aluminum alloy billets. Our heavy-duty wall thicknesses range from 2.0mm to 3.5mm, preventing deflection under severe wind loads while comfortably carrying architectural double-leaf panels weighing over 350 kg per leaf.
Featuring multi-chambered Technoform PA66 GF25 fiberglass-reinforced polyamide thermal insulation strips, our double swing assemblies achieve continuous thermal isolation. This effectively halts interior condensation and yields overall system U-values as low as 1.1 W/m²·K.
Seamless vulcanized continuous EPDM ternary ethylene-propylene rubber compound gaskets paired with drop-down automatic acoustic threshold drop seals deliver air tightness rated at ASTM E283 Level A4 and water resistance exceeding 700 Pa under driving rain conditions.
| Performance Attribute | DERCHI Engineered Double Swing Door | Standard Commercial Alternative | Standard Timber Entrance |
|---|---|---|---|
| Core Base Alloy | Virgin 6063-T6 Aluminum (2.0–3.5mm wall) | Recycled 6063 Alloy (<1.4mm wall) | Solid / Engineered Softwood Core |
| Thermal Transmittance (U-Value) | 1.1 – 1.6 W/m²·K (Multi-chamber PA66) | 2.8 – 3.8 W/m²·K (Non-thermal break) | 1.9 – 2.4 W/m²·K (Degrades over time) |
| Acoustic Isolation Index (Rw) | 38 dB to 44 dB (With Low-E Laminates) | 26 dB to 30 dB (Standard monolithic) | 28 dB to 32 dB (Joint leakage prone) |
| Wind Load Resistance | Class N6 / ASTM E330 > 5.0 kPa (Typhoon) | Class N3 / ~ 2.0 kPa | < 1.5 kPa (High flex hazard) |
| Biological & Moisture Aging | Zero rot, zero swelling, 100% termite-proof | Subject to anodic oxidation pitting | Prone to rot, warping, swelling, pests |
For property developers, lead architects, and institutional contractors, specifying the correct fenestration systems requires anticipating legislative, aesthetic, and structural shifts. Here is where the global market is heading through 2030:
Luxury commercial architecture is phasing out bulky multi-hinge profiles in favor of full-height, concealed 3D-adjustable European pivot-swing mechanisms. Modern double swing portals routinely exceed 3.2 meters in height, demanding advanced moment-of-inertia cross-sections that DERCHI manufactures via custom dies.
Double swing systems increasingly integrate directly into building management systems (BMS). Procurement trends reveal rising demand for concealed magnetic multi-point motor locks, biometric facial recognition terminals, smart keycards, and fail-safe fire evacuation automatic release mechanisms compliant with UL and CE directives.
International green building rating systems (LEED, BREEAM) reward manufacturers utilizing low-carbon hydroelectric-smelted aluminum profiles. DERCHI is pioneering eco-conscious supply chains with certified recycled alloy streams, reducing embodied carbon metrics across large-scale commercial tenders.
Headquartered in Shishan Town, Nanhai District, Foshan—China's world-leading aluminum industrial cluster—Guangdong Dejiyoupin Doors and Windows Co., Ltd. represents more than a quarter-century of engineering precision.
We do not rely on generic catalogue specs. Our team of 40+ engineering draftsmen generates project-specific shop drawings, structural wind-load calculations, structural mullion deflections, and BIM objects within 48 hours to accelerate planning approval cycles.
Our double swing doors hold comprehensive laboratory credentials including European CE certification, ISO 9001 quality management, AS 2047 Australian cyclone and wind pressure testing (N6 rated), and certified UL fire door assemblies.
Direct CIF/FOB global deliveries. Every door is wrapped in protective adhesive masking, encapsulated with high-density EPE foam corner protectors, and securely packed into fumigated ocean-grade solid plywood crates to ensure zero damage upon site arrival.
