Manufacturing Prowess & Verification
Global Production Powerhouse for Austrian B2B Specifiers
With over 25 years of specialized door and window manufacturing excellence, our Guangdong Dejiyoupin (DERCHI) infrastructure serves demanding commercial contractors across Graz, Linz, Salzburg, and Vienna.
Advanced Automated CNC Extrusion
Our 180,000㎡ smart manufacturing base utilizes multi-axis CNC milling centers capable of sub-millimeter tolerances on heavy 6063-T6 aluminum alloys. We guarantee the structural co-extrusion flatness and structural continuity required by Central European glazing standards.
ISO9001, CE & AS2047 Certification
Holding full CE compliance according to EN 14351-1 for external doors and windows, our systems carry air-tightness class 4, water tightness up to class 9A, and wind resistance up to class C5 under EN 12210, certified for European trade operations.
Precision Polyamide Thermal Barriers
Our aluminum clad composite doors incorporate multi-cavity, glass-fiber reinforced Polyamide 66 (PA66 GF25) thermal isolators, effectively breaking thermal conductivity bridges and eradicating dew point condensation issues during harsh Austrian sub-zero winters.
Regional Climate Engineering
Architectural Application Scenarios Across Austria
Austria's topography spans from high-alpine thermal extremes to dense urban corridors, necessitating diverse mechanical performance parameters.
Alpine High-Altitude Villas
Tyrol & Vorarlberg Alpine Architecture
Exposed to severe snow accumulation, heavy wind gust velocities, and large diurnal temperature swings ($\Delta T > 35^\circ\text{C}$). Our exterior powder-coated aluminum clad profiles resist UV degradation and frost-jacking, while inner European timber or solid insulated cores provide warm interior aesthetics.
Urban Modern Refurbishment
Vienna & Graz Multi-Family Living
Metropolitan projects demand stringent acoustic isolation under ÖNORM B 8115-2. Our double and triple glazing systems paired with perimeter EPDM gasket compression profiles achieve sound reduction indices exceeding $R_w \ge 42\text{ dB}$, blocking urban rail and automotive noise.
Commercial & Hospitality Envelopes
Salzburg & Carinthia Lakeside Resorts
High-frequency public portals requiring thermal efficiency combined with ÖNORM EN 1627 RC3 burglary resistance. Featuring anti-lift hardware, concealed multi-point lock pins, and corrosion-inhibiting Qualicoat Class 2 finishes designed for year-round lakeside moisture exposure.
Regulatory & Future Outlook
Austrian Fenestration Dynamics: 2026+ Outlook
Regulatory shifts and environmental mandates continue to transform the procurement requirements of Austrian construction companies.
Aggressive Thermal Requirements (OIB Richtlinie 6)
The Austrian Institute of Construction Engineering (OIB) mandates increasingly strict primary energy limits. Standard double glazing is largely phased out in new builds. B2B procurement now demands external doors achieving whole-element $U_d \le 0.85\text{ W/(m}^2\text{K)}$, pushing factories to use warm-edge spacers, krypton/argon infills, and multi-chambered insulating cores.
Cradle-to-Cradle (EPD) & Circularity Verification
General contractors across Austria frequently mandate Environmental Product Declarations (EPD) to secure Green Building Certifications such as DGNB and klimaaktiv. Derchi integrates circular low-carbon primary aluminum alloys and non-toxic powder coating processes, guaranteeing full documentation for sustainable lifecycle compliance.

Frequently Asked Questions for Austrian Importers
Key operational, logistical, and technical questions addressed for developers, architects, and trading houses.
Are your aluminum clad doors fully compliant with Austrian CE and OIB building codes?
Yes. All external aluminum clad entrance systems manufactured by our facility conform to CE marking requirements outlined in EN 14351-1. We supply the official Declaration of Performance (DoP) together with complete test certificates covering thermal transmittance ($U_w/U_d$), airtightness, water tightness, and acoustic indices. These certificates allow Austrian structural engineers and building control authorities (Baupolizei) to verify compliance directly against OIB Richtlinie 6 and national annexes.
How do you resolve thermal bridging at the threshold to avoid frost and condensation?
We implement custom thermally separated composite sub-thresholds engineered with Polyamide PA66 insulators and high-density foam sub-bases. This ensures that the isothermal line runs uninterrupted from the screed insulation layer through the door frame, totally preventing condensation formation, frost accumulation, and floor cooling, compliant with ÖNORM B 5320 installation conventions.
Can we request custom RAL architectural colors and specific European hardware brands?
Absolutely. Exterior aluminum extrusions can be powder-coated in any custom RAL classic color, textured fine-structure finish, or anodized palette meeting Qualicoat Class 2 standards. For operating hardware, we natively integrate German and Austrian systems, including Siegenia, Roto, GU (Gretsch-Unitas), or Winkhaus multi-point automated perimeter locking systems, guaranteeing effortless local maintenance and replacement parts compatibility.
What is the lead time, shipping route, and customs handling process for deliveries to Austria?
Custom fabrication runs generally require 25 to 35 calendar days following shop-drawing signoff. Containerized ocean freight is dispatched from our Foshan production facility to European entry ports such as Hamburg, Rotterdam, or Koper (Slovenia). For Southern Austria (Carinthia, Styria), shipping via Koper offers a rapid transit time of roughly 24–28 days at sea, followed by rail/truck carriage direct to your logistics warehouse or job site, supported by full export customs clearance documentation.
