Featured Aluminium Window & Door Systems
High-performance custom profile solutions engineered for B2B distributors, architects, and commercial developers across Germany and the DACH region.
Engineering Specifications & Compliance for the German Market
As a dedicated OEM/ODM aluminium internal doors factory, we understand that supplying the German construction and interior design sector requires rigorous engineering discipline. German builders, project developers, and architectural specifiers demand uncompromising adherence to structural integrity, tight dimensional tolerances, sound dampening standards, and aesthetic precision. Our manufacturing processes are customized to meet and exceed the standard specifications governing interior door construction in Germany (Deutsches Institut für Normung).
DIN 18101 Standardized Sizing
Full custom profile fabrication matching standard German door leaf measurements (Rohbaumaß and Bautenschutz dimensions). We ensure exact frame-to-wall recess tolerances, compatible with standard German wall thicknesses (Wandstärke) from 80mm to 300mm.
Acoustic Dampening (DIN 4109)
Interior glass aluminium doors for office partitions and luxury residences feature double EPDM perimeter drop-seals and acoustic laminated glass, achieving sound reduction index ratings from Rw 32 dB to Rw 48 dB (SSK III & IV).
Qualicoat & Qualanod Finish
Surface treatments tailored to high-end European architectural aesthetics. We provide anodic oxidation (15–25 µm) resistant to chemical disinfectants, alongside Qualicoat Class 2 hyper-durable powder coatings engineered for scratch resistance.

Localized Application Scenarios across Germany
Our factory custom fabricates profiles to match the regional climate requirements, municipal building codes, and design trends of major German metropolitan regions.
Commercial Fit-Outs (Frankfurt & Munich)
High-density office towers require sleek modular acoustic wall partitions. Our aluminium swing and sliding door profiles integrate effortlessly with double-glazed glass walls, providing privacy in open-plan banking and corporate environments while preserving ambient daylight.
Barrier-Free Modern Living (Berlin & Hamburg)
In accordance with DIN 18040-1/2 accessibility guidelines for modern residential buildings, our ultra-narrow sliding door systems feature zero-threshold flush bottom tracks, enabling smooth wheel-chair access without sacrificing draft protection.
Medical & Cleanroom Facilities (Stuttgart & Cologne)
Custom ODM internal door systems featuring anodized anti-microbial surface finishes, specialized rubber magnetic perimeter seals, and flush-mounted glass elements that eliminate dirt traps, supporting rigorous hygienic cleaning regimes.
Hospitality & Luxury Boutique Hotels
Slim black anodized and bronze finished internal frame systems tailored for luxury hotel suites. Designed with integrated magnetic latch locks and concealed drop-seals to deliver near-silent closing acoustics for hotel guests.
Factory OEM/ODM Manufacturing Capabilities
We provide full-spectrum engineering support from initial CAD concept drawings to high-volume extrusion, CNC fabrication, and custom hardware integration.
5-Axis CNC Precision Machining
Equipped with high-precision 5-axis CNC machining centers capable of milling hardware pockets, lock cylinder slots, and concealed hinge recesses to within ±0.1mm tolerance, ensuring seamless installation of European hardware standard parts.
Custom Die Extrusion Service
We develop proprietary extrusion dies for custom profile geometries. Whether you require micro-slim sightlines or heavy-gauge structural jambs, our tooling facility delivers prototype samples within 15 to 20 working days.
Strict Quality Assurance Protocol
Every single door frame assembly undergoes pre-rigging testing, anodizing film thickness checks (ISO 2360), coating adhesion cross-cut testing (ISO 2409), and drop-seal operational cycling tests prior to export packaging.
Structured OEM/ODM Co-Operation Workflow
Designed for German B2B importers, hardware distributors, and general contractors who require transparent project tracking and strict delivery timelines.
Drawing Review
Review of architectural CAD files, wall details, and target acoustic specs.
3D Prototype
CAD shop drawings & 3D section samples provided for client sign-off.
Extrusion & CNC
Tooling setup, aluminium extrusion, automated milling, and surface treatment.
System Assembly

Industry Development & Sustainability Trends in Germany
Key architectural and regulatory shifts driving the selection of aluminium interior door profiles across the European Union.
Circular Economy & Recycling (EPD)
With the tightening of the German Building Energy Act (GEG) and DGNB green building certification criteria, our aluminium profiles utilize low-carbon recycled aluminium billets. All profiles come with Environmental Product Declarations (EPD) data sheets for seamless green project scoring.
Concealed Hardware & Smart Locks
Modern German interior design heavily favors invisible hardware integration. Our profiles feature internal wall reinforcement channels designed for 3D adjustable concealed hinges (e.g., Simonswerk TECTUS), soft magnetic latch mechanisms, and biometric access control wire-ways.
Modular Acoustic Partitioning
Post-pandemic workplace restructuring across German financial and technological hubs has created high demand for demountable, reconfigurable glass aluminium internal partition doors that maintain high privacy (Rw > 40 dB) without permanent structural wall alterations.
Frequently Asked Questions by German Importers & Contractors
Clear answers regarding technical compliance, custom tooling, logistics, customs clearance, and ordering procedures.
Are your aluminium internal door profiles fully compatible with DIN standard hardware?
Yes. Our extrusion profiles are specifically designed with Euro-groove channels and mortise lock cutouts tailored to standard German hardware manufacturers including Dormakaba, GEZE, Simonswerk, and FSB. Custom milling layouts can also be programmed into our CNC machines for proprietary hardware.
How do you guarantee compliance with sound insulation standard DIN 4109?
We utilize multi-chamber aluminium profiles combined with thermal break insulating strips, heavy-duty EPDM perimeter gaskets, acoustic glass options (such as 6mm + 0.76PVB + 6mm acoustic laminated glass), and automatic drop-down door bottom seals. We provide official laboratory sound transmission loss test reports upon request.
What is your typical production lead time for sea freight shipments to Hamburg?
Standard profile production and custom powder coating usually require 20 to 25 calendar days. For custom die extrusion development, add 15 days for tooling. Transit time from our factory port to major German sea ports (Hamburg or Bremerhaven) is approximately 28 to 35 days.
Do you support customized color finishing matching German RAL codes?
Absolutely. We feature advanced powder coating lines supporting the complete RAL Classic chart, including popular German architectural shades such as RAL 9005 (Jet Black), RAL 7016 (Anthracite Grey), and RAL 9016 (Traffic White), in matte, satin, or fine-textured finishes.
How are products protected against transport damage during container transit?
All finished door frames and glass elements are wrapped in protective anti-scratch surface film, fitted with heavy-duty corner protectors, interleaved with foam sheets, and packed into ISPM-15 certified fumigated wooden crates or steel transport racks.
What is the minimum order quantity (MOQ) for OEM custom extrusion profiles?
For standard profile shapes in stock, our MOQ is 50 door sets. For custom OEM extrusion profiles requiring dedicated dies, our MOQ is 500 kg per profile section, with die fees waived upon reaching threshold contract volumes.
