Precision-manufactured in Foshan, China with international CE, NFRC, and AS2047 compliance. Designed to withstand mountain wind loads, tropical rain deluges, and the contemporary aesthetic requirements of Colombian luxury villas and multi-family high-rises.
Medellín's unique elevation (1,500m above sea level) combined with dramatic topography requires specialized fenestration. From the breezy ridgelines of El Poblado to the urban core of Laureles, our aluminum double swing doors solve structural, thermal, and security challenges.
Residential architectures nestled on steep hillsides face relentless Andean valley updrafts and seasonal torrential rainfall. Our heavy-duty double swing doors feature multi-tier EPDM vulcanized perimeter seals and polyamide thermal breaks (PA66GF25), eliminating whistling under high pressure, maintaining structural deflection tolerance, and seamlessly connecting grand living zones to expansive terraces overlooking the valley skyline.
Security remains a vital design factor for residential enclaves in Envigado, Sabaneta, and Laureles. DERCHI provides an exclusive patented Four-Side Six-Point Anti-Theft Lock integrated into seamless 6063-T6 aluminum extrusion frames. Equipped with laminated anti-intrusion glass (PVB/SGP interlayers), our entrance swing systems resist forced mechanical intrusion without sacrificing sleek European aesthetics.
Medellín's booming tourism and digital nomad hospitality sector demands grand entrance portals with continuous high-cycle operation. Our double swing commercial doors utilize German hardware systems rated for over 500,000 cycles, heavy-duty adjustable concealed 3D hinges, and dual Low-E acoustic double glazing that shuts out vibrant street noise for hotel guests.
The Medellín architectural landscape has undergone an aesthetic renaissance. Dubbed the "City of Eternal Spring" (Ciudad de la Eterna Primavera), local design philosophy centers on biophilic integration, indoor-outdoor permeability, and minimalist framing profiles. However, tropical mountain realities are driving strict technical specifications:
| Performance Parameter | Generic Local / Standard Systems | DERCHI High-Performance Engineered Solution | Benefit to Medellín Developers |
|---|---|---|---|
| Alloy Composition & Wall Thickness | Recycled aluminum, variable 1.2mm – 1.4mm profile | Virgin 6063-T6 Architectural Grade, structural 2.0mm – 3.0mm wall | Zero deflection under Andean wind loads; no warping across tall leaves up to 3.5m. |
| Surface Finish & Weatherability | Standard domestic powder coating (40–50 microns) | AkzoNobel / PPG Fluorocarbon (PVDF) or Marine Anodizing (60–80 microns) | Immunity to intense high-UV solar degradation at 1,500m+ altitude; color-fast for 20+ years. |
| Infiltration & Sealing System | Standard PVC / generic rubber weatherstrips | Automotive-grade EPDM co-extruded foam gaskets with drainage baffling | Completely eliminates tropical mountain storm water penetration and whistling drafts. |
| Acoustic Insulation (Rw/STC) | Single monolithic glass (Rw ~22 - 25 dB) | Double/Triple insulated Low-E + Argon gas + Acoustic laminated (Rw 38 - 44 dB) | Blocks urban street cacophony, entertainment district noise, and thunderous rain reverberation. |
| Locking Security Mechanics | Single latch point mechanism | Patented 4-Side 6-Point Anti-Theft multi-point lock with hardened steel pins | Maximum residential burglar resistance without requiring unsightly exterior iron grilles. |
Operated by Guangdong Dejiyoupin Doors and Windows Co., Ltd., DERCHI pairs 25+ years of fenestration excellence with massive 180,000 m² automated production infrastructure to supply Latin America's landmark developments.
Located in the heart of China's aluminum industrial cluster (Foshan), our smart CNC machining centers execute micron-accurate profile cutting, corner crimping, and computerized glazing injection, churning out over 1,000,000 m² of certified fenestration annually.
Recognized by global media titan Xinhua News Agency and honored with national engineering accolades, our dedicated R&D team holds over 100 patents, including specialized water weep cascades, thermal isolators, and proprietary security multi-locks.
Every extrusion batch undergoes spectral alloy tests, structural shear checks on thermal polyamide bars, hardware load cycling tests, and mock-up pressurized air/water chamber testing prior to multi-layer crate packing for maritime shipping.
Our fenestration series are officially certified to international criteria: European CE, North American NFRC energy performance ratings, Australian AS2047 fenestration compliance, Canadian CSA, Energy Star, and ISO 9001 quality management protocols.
Avoid coordinating fragmented suppliers. We produce coordinated exterior double swing doors, sliding multi-track balcony doors, thermal break casement windows, structural glass sunrooms, and interior solid wooden/slim glass doors under one uniform factory warranty.
We provide full export-ready wooden crating with internal shock-absorbing EVA foam, fumigated timber pallets, exact opening-by-opening labeling schedules, and direct sea-freight handling with complete DIAN-compliant customs documentation packages.
Straightforward answers covering logistics, Colombian construction code compliance, lead times, and on-site engineering installation protocols.
