Engineered with high-tensile casting alloys, multi-point anti-burglary locks, and thermally broken core structures optimized for Ireland's maritime climate.
Ireland’s construction and residential redevelopment sector is undergoing a profound transformation. Driven by stringent modern energy performance benchmarks, such as Part L of the Irish Building Regulations (nZEB - Nearly Zero Energy Buildings), property developers, architects, and luxury homeowners in Dublin, Cork, Galway, and Limerick are demanding entrance systems that seamlessly blend high security, structural endurance, and exceptional thermal efficiency.
The Irish climate poses a unique set of engineering challenges for exterior building envelopes. Facing fierce wind-driven rains from the North Atlantic, severe salt-laden air along coastal regions, and frequent driving dampness, traditional timber entrance doors are prone to warping, moisture absorption, and rot. Conversely, standard mild-steel doors suffer from accelerated corrosion and cold-bridging issues. This environment has created a rapidly expanding demand for Architectural Cast Aluminum Entry Doors engineered with thermal break technology.
Designed to withstand Class C5 (EN 12210) wind loads up to 3000 Pa, resisting gale-force Atlantic storms prevalent along the Wild Atlantic Way and coastal Dublin developments.
Integrated PA66 polyamide thermal breaks and polyisocyanurate (PIR) cores deliver door leaf U-values down to 1.1 - 1.4 W/m²K, optimizing Building Energy Ratings (BER).
Reinforced anti-prying sub-frames, multi-point hook latch systems, and anti-drill manganese plates guarantee protection compliant with European EN 1627 security standards.
Combining 25+ years of metallurgical casting mastery, high-capacity automated production lines, and strict European quality auditing.
Unlike cheap stamped aluminum sheets or thin hollow profiles, DERCHI cast aluminum doors utilize high-purity A356 aluminum alloy sand-casting and precision vacuum die-casting. Our cast panels range from 6mm to 12mm in solid thickness, achieving extraordinary 3D relief depths, structural integrity, and natural sound dampening (acoustic isolation up to 38 dB).
Our Foshan facility integrates the complete manufacturing value chain: raw alloy smelting, CNC 5-axis mold milling, hand polishing, automated PVDF (Fluorocarbon) baking, and automated thermal-break frame assembly. This vertical integration allows us to offer custom bespoke architectural doors at 30% to 50% lower lead times and costs than local European niche manufacturers.

Addressing architectural, engineering, and commercial procurement inquiries regarding cast aluminum entry doors.
Yes. Our cast aluminum entry doors are engineered with multi-chamber thermally broken profile systems and polyisocyanurate (PIR) insulated cores. They achieve verified U-values starting from 1.1 W/m²K, comfortably exceeding Ireland's Part L standard threshold of 1.4 W/m²K for new residential developments and energy retrofits.
Solid A356 cast aluminum possesses natural anti-corrosion properties because it contains zero ferrous metals (iron). Furthermore, all door surfaces undergo multi-stage pretreatment and PPG/AkzoNobel Fluorocarbon (PVDF) architectural powder coating. This prevents oxidation, blistering, and color degradation even in marine environments exposed to severe Atlantic salt spray (C5-M rating).
CAD drawing approval and custom mold preparation usually take 10-15 days. Factory fabrication requires 25-35 days depending on design complexity. Direct ocean freight from Shenzhen/Foshan to Dublin Port or Cork Port typically takes 28-35 days. We recommend planning for an overall lead time of 8-10 weeks from deposit to site delivery.
Absolutely. Our dedicated architectural support team provides complimentary 2D CAD shop drawings, 3D section renderings, and BIM blocks matching your exact project opening schedules. We adjust frame depth, sill details, and anchoring points to accommodate traditional Irish cavity wall constructions.
We incorporate European multi-point gearboxes with heavy-duty anti-lift hook bolts. We seamlessly integrate leading smart biometric access solutions, including 3D facial recognition, fingerprint scanners, keypad entry, and smartphone app integration (Tuya / Zigbee / Smart Life / HomeKit compatibility).
Whether you are an Irish developer sourcing doors for a luxury villa project, an architect seeking bespoke entrance drawings, or a building material distributor expanding your high-end catalog, DERCHI delivers unmatched factory-direct quality.
