As commercial redevelopment thrives across Prague, Brno, and Ostrava, the demand for precision-fabricated, thermally uncompromised, and acoustic-rated interior aluminum doors has surged. Guangdong Dejiyoupin Doors and Windows Co., Ltd. (DERCHI) bridges high-throughput Chinese smart manufacturing with stringent European technical benchmarks (ČSN EN 14351-1 / EN 12150), delivering direct OEM/ODM wholesale capabilities designed for Czech architectural realities.
Tested for endurance, micro-tolerance alignment, and high-performance sound dampening.
Heavy-duty multi-leaf folding mechanism with integrated acoustic damping. Ideal for flexible open-space interior segmentation in modern Czech tech hubs and multifunctional venues.

Product SpecsThe Czech architectural landscape presents a distinctive intersection of preserved functionalist heritage (such as the Functionalist Bauhaus traditions in Brno) and rapid class-A corporate expansions across Prague 4, Karlín, and Smíchov. Our aluminium framed internal door solutions address three core localized applications:
Prague's expanding IT, financial, and outsourcing sectors demand flexible spaces. DERCHI's minimalist glass partition doors offer acoustic attenuation (Rw 32 dB to 42 dB) for confidential boardrooms, phone booths, and collaborative zones without sacrificing daylight penetration.
Historic tenement buildings across Vinohrady and Holešovice require high-ceiling partition systems with transoms that do not place excessive structural weight on timber-joisted floors. Our lightweight, 6063-T5 aerospace extruded aluminium internal doors provide structural stability without warping.
Czech building codes strictly enforce energy conservation via the Nová zelená úsporám initiative. Our flush-mounted interior sliding and pocket doors allow zoning off heating sectors, maintaining regulated thermal envelopes throughout micro-climatic household zones.
Understanding shifting procurement dynamics within the Czech construction and interior finishing sectors.
The transition of industrial brownfields in Ostrava and Liberec into creative lofts has normalized the black anodized (RAL 9005) thin-framed internal door profile. Czech architects prioritize ultra-narrow sightlines (≤ 18mm visible stiles) paired with safety-toughened fluted or tinted acoustic glass.
European standard EN ISO 140-3 enforcement has elevated acoustic compliance from a luxury to a mandatory handover criterion for developers. Internal doors are increasingly expected to feature concealed drop-down bottom seals and multi-chamber perimeter magnetic gaskets to prevent sound leakage.
Unlike MDF or composite wood interior doors, which can emit volatile organic compounds (VOCs) and warp under seasonal heating-cycle humidity shifts, circular aluminium retains 100% recyclability. This aligns with EU Green Deal mandates rapidly embraced by Czech general contractors.
Ranked among China's Top 10 door and window manufacturers, our Foshan smart facility provides unparalleled scalability, compliance, and custom fabrication for international distributors.
Eliminate wholesale intermediaries while retaining full European technical compliance and quality assurance.
Our aluminium partition lines comply with CE, ISO 9001, AS 2047, and relevant EN structural deflection criteria. Complete test certificates and technical datasheets are supplied for smooth approval by Czech municipal building authorities (Stavební úřad).
Our in-house engineering desk converts your architectural door schedule and DWG floor plans into precise manufacturing shop drawings, specifying profile cross-sections, glass thicknesses, hinge positioning, and zero-clearance threshold details within 48 hours.
Experienced in containerized export shipping directly into major multimodal hubs serving the Czech Republic (including Hamburg, Koper, or direct rail freight via the Yiwu-Prague line). Every door is packed in seaworthy, reinforced fumigated timber crates with anti-scratch protective films.
Clear, direct answers regarding custom manufacturing, local compliance, freight logistics, and technical specifications.
Yes. All glass used in our internal casement and sliding partition doors is fully toughened safety glass certified under EN 12150 (ČSN EN 12150), with optional acoustic or fire-resistant PVB laminated options compliant with European fire classification ratings. We provide full glass manufacturer conformity certificates with each shipment batch.
Absolutely. Standard European doors are limited to 2,100 mm, but our heavy-extruded aluminium frames and structural pivot/hinge systems support leaf heights up to 3,200 mm (and ceiling-height transoms up to 4,000 mm) with zero bowing or hinge fatigue. Perfect for historic Prague and Brno apartments.
Our aluminium profiles can be CNC-milled to accept either proprietary high-cycle concealed hardware or standard European mortise locks, DIN cylinder locks, magnetic latch latches, and flush pull handles from brands like HOPPE, Dormakaba, or Geze, ensuring seamless integration with master key systems.
Factory fabrication takes approximately 20 to 30 working days following shop drawing approval. Ocean transit to Hamburg or Koper port typically takes 28–35 days, followed by rail/truck connection directly to your project site or warehouse in Prague, Brno, or Plzeň. Express rail freight (18–22 days transit) is also available.
Every internal door panel is wrapped in protective self-adhesive scratch-resistant film, padded with shock-absorbing foam corner guards, and sealed inside fully enclosed, fumigated solid plywood crates. We provide photo/video inspection proof prior to container loading at our Foshan facility.
We accommodate both project-based batch orders and regular container procurement. For bespoke custom designs, our minimum order quantity starts as low as 10 sets, making it practical for boutique residential developments, high-end office fit-outs, or showroom sample sets.
Send us your door schedule, project drawings, or specific opening measurements. Our engineering team provides complimentary CAD shop drawings, structural glass calculations, and DDP/CIF quotation within 24 hours.
