Engineered in Foshan, customized for Istanbul's coastal wind-loads, thermal insulation standards, and architectural design benchmarks.
Istanbul stands at the geographical and cultural crossroads of Europe and Asia, serving as Turkey's economic heartland and real estate powerhouse. The metropolis is currently experiencing an unprecedented wave of urban transformation (Kentsel Dönüşüm), characterized by ultra-luxury residential developments in districts like Beykoz, Zekeriyaköy, and Tarabya, alongside towering high-rise commercial corridors in Maslak, Levent, and Ataşehir. For general contractors, facade consultants, and real estate developers in Istanbul, sourcing high-spec exterior entry doors requires balancing aesthetic distinction with brutal environmental and regulatory mandates.
As a premier China Entry Door Manufacturer & Supplier targeting the Istanbul market, DERCHI brings a vertically integrated 180,000 m² industrial ecosystem from Foshan directly to Turkish project sites. Sourcing directly from top-tier Chinese manufacturers allows Turkish buyers to access elite architectural engineering—such as thermal-break extruded aluminum profiles, heavy-duty sand-cast aluminum panels, structural pivot systems, and smart biometric multi-point locking mechanisms—at cost structures that outperform European imports by 35% to 50% while fully complying with CE (TS EN 14351-1) standards.
Istanbul's coastline exposes exterior doors to severe marine aerosol corrosion, high salt air, and rapid seasonal thermal swings between the humid Marmara Sea and cold Black Sea fronts. Our PVDF and anodized surface treatments exceed 3,000-hour salt spray endurance tests.
Located within active seismic regions (North Anatolian Fault Zone), Istanbul structural codes mandate rigorous structural deflection resistance. DERCHI doors feature reinforced 6063-T5 aluminum alloy frames capable of withstanding wind pressure ratings exceeding 3,000 Pa (AS2047 N6 benchmark).
Dense urban traffic in central Istanbul requires superior soundproofing. Equipped with double/triple EPDM continuous weather stripping and multi-chambered insulating glass units, our door systems deliver acoustic attenuation up to 38 dB-42 dB STC.
Integrating structural durability, thermal efficiency, and security into custom architectural entrance systems.
Designed for modern luxury villas in Zekeriyaköy and Bodrum, our grand pivot doors feature 80mm-120mm depth profile frames integrated with Technoform PA66 polyamide thermal break strips. Capable of supporting single leaf dimensions up to 2,000mm x 4,000mm, these systems utilize floor-concealed heavy-duty hydraulic pivots rated for 500kg+ loads, providing effortlessly smooth opening dynamics paired with low U-values (down to 1.6 W/m²K).
Reflecting the regal Ottoman aesthetic preferred in classical Istanbul mansions and private compounds, our solid sand-cast aluminum doors utilize 6mm-12mm thick cast panels. Unlike thin stamped metal, cast aluminum provides high relief depth, extreme impact resistance, and zero risk of rust. Finished with multi-layer hand-rubbed patinas and fluorocarbon protective coatings, these gates maintain structural integrity for over 30 years.
Engineered specifically for Bosphorus waterfront (Yalı) properties and commercial bank/embassy entrances requiring maximum force-entry deterrence. Constructed with 1.5mm-2.0mm SUS316 stainless steel skins over steel-reinforced structural honeycombs or rock-wool acoustic cores. Integrated with German Hoppe or GU 7-point motorized locking gear boxes and anti-pry hardware.
Tailored for high-end boutique hotels in Beyoğlu and commercial towers in Maslak. Utilizing heavy-duty aluminum perimeter framing holding 8mm Low-E + 12A + 8mm toughened double or triple laminated glass units. Offers solar control, maximum natural daylighting, UV shielding, and seamless integration with automatic sensor sliding mechanisms or card-access control.
Direct comparative specifications measured during factory acceptance testing (FAT) under ISO 9001 quality management.

Seamless logistics execution, customs compliance, and documentation support for Turkish importers and contractors.
Turkey operates under the EU-Turkey Customs Union, requiring products to satisfy CE marking standard TS EN 14351-1. All DERCHI door orders include factory test reports for thermal transmittance, air permeability, water tightness, and wind load resistance issued by accredited laboratories, ensuring frictionless customs clearance with your Turkish customs broker (Gümrük Müşaviri).
Ocean freight from ocean hubs (Nansha/Shekou) to Istanbul ports (Ambarlı, Haydarpaşa, or Gebze) typically takes 22 to 28 days. Every door leaf undergoes protective film wrapping, EPE foam corner guarding, vacuum sealing, and encapsulation in heavy-duty fumigation-free OSB plywood crates to prevent marine transit damage.
To eliminate site misfits, our engineering department provides complimentary CAD shop drawings, section details, structural anchoring schedules, and BIM blocks prior to production. We align hardware cutouts precisely with specified smart locks (Dormakaba, Yale, or Tuya biometrics).

While Turkey has a robust aluminum fabrication industry, China's Foshan hub offers unparalleled vertical integration for complex, custom architectural door systems. DERCHI operates custom die extrusion, heavy sand-casting foundries, automated anodizing, and structural pivot manufacturing under one 180,000 m² facility. This allows us to deliver oversized pivot doors (up to 4m height), cast aluminum relief doors, and marine-grade thermal break profiles at costs 30-40% lower than European alternatives, backed by total customization freedom.
All DERCHI entry door series are tested according to EN 14351-1 standards, covering air permeability (EN 12207), water tightness (EN 12208), wind load resistance (EN 12210), and thermal transmittance (EN ISO 10077-2). Test certificates and declaration of performance (DoP) documents are included with shipment documentation, facilitating seamless authorization by Turkish building inspectors and customs authorities.
Bosphorus coastal locations endure extreme wind pressures. Our pivot doors utilize heavy-wall 6063-T5 aluminum extrusions (2.5mm to 3.0mm wall thickness) reinforced with internal steel spine stiffeners. Coupled with German Dormakaba BTS floor-spring pivot mechanisms rated up to 500kg and perimeter EPDM magnetic gaskets, our doors achieve air tightness and wind resistance rated up to 3,000 Pa (equivalent to Category 5 storm wind pressures).
Engineering CAD drawing confirmation takes 3 to 5 business days. Manufacturing lead time is approximately 25 to 30 days depending on profile finish (such as specialized fluorocarbon PVDF or custom wood grain transfers). Direct ocean transit from Shenzhen/Guangzhou ports to Ambarlı or Haydarpaşa Port takes 22 to 28 days. Total door-to-port time is usually within 55 to 65 days.
Yes. We factory-prep door frames and leaves with precision CNC mortise cutouts for all leading smart lock platforms, including 3D face-recognition biometrics, fingerprint scanners, RFID keycards, Tuya/Zigbee smart home integrations, and mechanical multi-point anti-theft deadbolts. Wiring channels are integrated internally during extrusion to keep power cables hidden.
