Manufactured in our 180,000 m² intelligent production hub in Foshan and shipped directly to projects in Lembang, Dago Pakar, Setiabudhi, and Kota Baru Parahyangan. All systems feature marine-grade 6063-T6 virgin aluminum, weather-tight multi-tier EPDM seals, and precision locking hardware.
Exterior multi-chamber structural aluminum paired with interior fine-grain timber. Features European PA66 GF25 thermal break insulation to prevent condensation during cold Lembang highland nights.
Architectural double-glazed tempered glass with integrated thermal louvers. Smooth motorized overhead lifting designed for hillside estates and high-exposure automotive courtyards.
Heavy-duty bottom-hung roller system accommodating up to 12 folding leaves. Creates 90% wide unobstructed outdoor openings for Bandung boutique resort pavilions and garden cafes.
Minimalist black fluorocarbon architectural profile with concealed hinges and multi-point perimeter locks. High wind-load deflection rating tested up to 3500 Pa for highland exposures.
Double-chamber thermal break framing with argon-filled low-emissivity glass. Delivers 42 dB sound attenuation against urban Bandung traffic along Pasteur and Dago thoroughfares.
Smooth multi-track stacking mechanism with flush floor track options and integrated flyscreens. Perfect for modern kitchen-to-patio serveries in West Java hospitality venues.
Geometric metal grilles with industrial narrow sightlines. Blends Bandung's Dutch colonial heritage architecture with contemporary minimalist open-plan spatial division.
Disappears seamlessly inside wall cavities. Engineered with soft-close dampers, corrosion-free stainless steel carriage trolleys, and high-impact decorative safety glazing.
Unlike Jakarta’s hot coastal plains, the Bandung basin sits elevated at 768 to 1,050+ meters above sea level, ringed by active volcanic topography including Tangkuban Perahu and Mount Tilu. This unique geography generates hyper-specific structural and thermal demands for exterior architectural systems.
Bandung regularly experiences diurnal temperature swings spanning 14°C to 16°C between crisp, foggy highland nights (16°C in Lembang) and sun-drenched afternoons (30°C+). Standard monolithic aluminum frames expand and contract abruptly, causing frame misalignment, warped leaves, and ruptured sealant beads. DERCHI applies reinforced polyamide (PA66 GF25) thermal breaks that neutralize structural thermal shock and halt internal glass condensation.
Annual precipitation in Northern Bandung exceeds 2,800 mm, driven by sudden high-velocity afternoon monsoons that batter hillside elevations. Conventional sliding tracks quickly overflow, flooding interior teak parquets. Our export systems feature multi-chamber step-down sub-sills with concealed pressure-relief drainage valves and continuous vulcanized EPDM gaskets that achieve water-tightness exceeding 600 Pa.
Airborne sulfur dioxide emissions drifting from active volcanic vents around Tangkuban Perahu combine with dense evening fog to form mildly acidic condensation. Inferior powder coatings blister and peel within 24 months. DERCHI specifies AkzoNobel Interpon D2015 fluorocarbon (PVDF) and architectural Qualicoat Class 2 finishes, certified to withstand 3,000+ hours of accelerated acetic salt-spray exposure without oxidation.
From mountain-perched villas in Dago Pakar to commercial leisure venues in Punclut, our factory-direct outdoor door solutions are purpose-matched to the unique structural topographies of West Java.
Cantilevered luxury homes built along steep volcanic contours face heavy valley winds and panoramic mountain vistas. Our heavy-duty Lift & Slide glass doors feature 2.5 mm wall thickness aluminum profiles and precision German-engineered stainless steel rollers that effortlessly glide 400 kg monolithic low-E glazed leaves while providing hurricane-grade wind bracing.
In high-elevation eco-resorts where agricultural tourism thrives, clients require unhindered views without interior chill. Thermal-break aluminum glass folding doors combined with integrated sunrooms create sealed botanical enclosures that trap daylight warmth and reject highland cold drafts during wet season months.
Bandung’s historic districts—such as Cipaganti and R.E. Martadinata—require sensitive architectural interventions. Our aluminum French casement swing doors replicate historical slim timber muntin sightlines while introducing modern multi-point locking security, termite immunity, and zero moisture-rot vulnerabilities.
Bandung’s vibrant lifestyle economy demands seamless transition between alfresco dining terraces and indoor seating. Custom multi-panel bifolding systems fold away completely to maximize seating footprint during warm weekends, yet lock down with weather-tight EPDM seals against torrential afternoon stormfronts.
Evaluating structural integrity, thermal efficiency, maintenance lifespans, and weather resilience under Bandung highland operational conditions.
