Modern Heavy Duty Cast Aluminum Security Entrance Door
- 8mm-12mm Solid Cast Aluminum Alloy Plate
- Multi-Point Arctic Anti-Theft Lockset
- Thermal Core: U-value ≤ 0.85 W/m²K
Specifically engineered with multi-chamber structural aluminum profiles, PA66 thermal barriers, and argon-filled Low-E glazing packages calibrated to withstand harsh Nordic sub-zero winters and coastal Baltic moisture.
Finland's building sector operates under some of the world's most rigorous thermal performance and weather-tightness directives. Our precision aluminum fabrication systems are optimized directly against the National Building Code of Finland (Suomen rakentamismääräyskokoelma).
Engineered for sustained exposure down to -40°C. Fabricated with multi-cavity polyamide 66 fiberglass-reinforced thermal breaks (PA66 GF25) eliminating internal condensation and freeze-lock in ski lodges and wilderness glass villas.
Structures in the Helsinki Archipelago, Hanko, and Turku face saline winds, driving rains, and relentless freeze-thaw cycles. Our doors feature Qualicoat Seaside certified powder coatings and marine-grade 316 stainless steel fittings.
Finnish mökki culture demands extreme interior-to-exterior climate isolation. Our aluminum-clad timber and heavy-duty sliding doors withstand dramatic interior humidity alongside sub-freezing exterior lake winds without warping.
Designed for public buildings in Helsinki, Espoo, and Vantaa needing accessibility under SFS-EN 17210 and energy ratings compliant with EU nZEB (nearly Zero-Energy Buildings) regulations. Features automatic concealed access systems.
| Performance Characteristic | Finnish Building Regulation Standard | Manufacturer Technical Specification | Architectural Benefit |
|---|---|---|---|
| Thermal Transmittance (U-Value) | Udoor ≤ 1.0 W/m²K (New Construction) | Ud = 0.72 - 0.85 W/m²K (Argon 90% Low-E) | Exceeds Passive House thresholds; cuts heating load |
| Air Permeability (EN 12207) | Class 3 Minimum | Class 4 Certified (Perimeter EPDM Gaskets) | Zero drafts during high Arctic winter pressure differentials |
| Watertightness (EN 12208) | Class 7A (300 Pa) | Class 9A / E1200 (Up to 1200 Pa) | Complete resistance to coastal Baltic horizontal storm rains |
| Acoustic Insulation (EN ISO 717-1) | Rw ≥ 30 - 35 dB (Urban zones) | Rw + Ctr = 40 - 45 dB | Eliminates urban transit rumble and blizzard howl |
| Structural Wind Load (EN 12210) | Class C2 / C3 | Class C5 (Tensile strength 6063-T6 alloy) | Prevents deflection across oversized door openings up to 4m |
Finland's commitment to climate neutrality by 2035 is radically transforming construction criteria. Discover the structural requirements shaping today's commercial and residential door specifications.
Finnish architectural practices (such as those specifying under RTS EPD criteria) prioritize primary aluminum smelted with renewable hydro-power and high post-consumer recycled billet content. Our precision extrusions minimize embodied CO² per square meter without compromising metallurgical rigidity.
Scandinavian modernism continues to demand expansive, monolithic spans with razor-thin sightlines. Contemporary Finnish villas favor floor-to-ceiling pivot entrance doors up to 4000mm in height, operating on concealed hydraulic floor-integrated pivots capable of effortlessly supporting door leaves exceeding 400 kg.
Modern Finnish residential clusters in Kalasatama and Pasila require keyless digital integration compatible with Scandinavian standard mortise locksets (e.g., Abloy lock profile standards). We pre-machine CNC routing channels for invisible motorized multipoint latching, biometric scanners, and smart home connectivity.
Guangdong Dejiyoupin Doors and Windows Co., Ltd. (DERCHI) stands among the world's premier fenestration and door manufacturing hubs. Backed by 25+ years of dedicated engineering and a sprawling 180,000 m² smart production facility, we manage the entire value chain: in-house aluminum billet extrusion, precision CNC corner-crimping, multi-stage automated surface treatment, and thermal barrier assembly.
For Finnish contractors, developers, and architectural studios, this vertically integrated capability eliminates middleman markups, guarantees CE compliance under EN 14351-1, and delivers turnkey CAD/BIM shop drawings tailored to complex Nordic schedules.
Clear, definitive technical answers covering European certifications, thermal criteria, import customs, and installation support across the Nordic region.
Yes. Finland's Ministry of the Environment sets reference U-values for exterior doors at 1.0 W/m²K. Our thermally broken aluminum fabrication systems achieve overall door values (Ud) between 0.72 and 0.85 W/m²K by utilizing 34mm-54mm polyamide (PA66 GF25) thermal insulation strips, aerogel insulation cores, and triple or quadruple argon-filled Low-E glazing with warm-edge spacers.
All door shipments are delivered with comprehensive CE documentation according to EN 14351-1:2006+A2:2016. We supply certified Declarations of Performance (DoP), structural wind load ratings (EN 12210), air leakage ratings (EN 12207), and glass safety certificates under EN 12150-1, satisfying local municipal inspectors across Helsinki, Espoo, Tampere, and Oulu.
Thermal bridging is strictly eliminated through an engineered multi-cavity barrier profile. The interior and exterior aluminum alloy sections are completely decoupled mechanically using high-rigidity structural polyamide. Coupled with triple-lip EPDM continuous perimeter seals, the interior aluminum surface temperature remains consistently above the dew point, preventing frost buildup and moisture condensation.
Yes. We regularly fabricate doors pre-routed using high-precision CNC multi-axis milling for European DIN lock cases, Scandinavian oval cylinders, and standard Finnish mortise configurations such as Abloy LC102, LC200, or EL560 motorized electromechanical locks. Shop drawings detailing exact backset, faceplate dimensions, and wire pass-throughs are confirmed with your engineers before production.
Our standard production lead time is 25 to 35 business days following CAD shop drawing approval. Maritime transit from our manufacturing headquarters via modern container vessels to the Port of Helsinki (Vuosaari) or Kotka generally takes 32 to 40 days. All items are packed in heavy-duty plywood export crates lined with anti-condensation desiccants and moisture-barrier membranes.
Over 80% of our architectural output is fully customized. We engineer oversized pivot doors up to 4000mm tall and multi-panel folding door systems spanning over 12 meters. Our engineering office provides bespoke finite element calculations (FEA) to confirm wind load deflection tolerances for expansive glazed elevations along open lakefronts or coastal islands.
Send your project blueprints, window schedules, or custom dimensions. Our senior fenestration engineers will provide compliant CAD/BIM shop drawings, thermal calculations, and competitive factory-direct export proposals within 24 hours.
