Engineered to withstand coastal Atlantic gales, meeting strict Irish Part L compliance & NZEB thermal standards.
The construction and architectural glazing landscape in Ireland is undergoing a structural paradigm shift. Driven by rigorous energy performance targets under the Nearly Zero Energy Buildings (NZEB) standard and updated Building Regulations (Technical Guidance Document Part L – Conservation of Fuel and Energy), specification requirements for residential and commercial sliding patio doors have reached unprecedented levels of strictness.
For Irish property developers, architectural metal fabricators, facade contractors, and trade stockists across Dublin, Cork, Galway, Limerick, and Waterford, procuring off-the-shelf door systems is no longer sufficient. Local environmental factors—specifically Ireland’s maritime climate, characterised by salt-laden Atlantic wind pressure, severe driving rain (often exceeding 1,500 Pascals of water tightness requirement), and intense thermal cycling—demand engineered Custom OEM Aluminum Sliding Patio Doors manufactured with millimetric precision.
Our direct-from-factory OEM manufacturing model bridges the gap between high-volume extrusion capabilities and local Irish architectural customization. By combining 53+ years of metallurgical expertise with certified AS9100 CNC machining and in-house chromate-free powder coating, we supply Irish fabricators with fully bespoke extrusion profiles, pre-milled thermal breaks, and coastal-grade threshold assemblies designed for rapid local assembly and seamless building site integration.
To deliver structural longevity and zero-maintenance operational reliability in Irish climate conditions, alloy selection and extrusion temper must be tailored to specific door components. We utilize virgin billet primary aluminum, controlling chemical composition to ensure optimum tensile strength, yield stress, and surface anodizing response.
The standard of excellence for main sliding door profiles. Delivers a ultimate tensile strength of ≥205 MPa, high surface finish quality for powder coating, and exceptional extrudability for complex hollow multi-cavity thermal break designs.
For subterranean drainage channels, sub-sill plates, and low-threshold tracks exposed to severe sea salt spray (Galway, Donegal, Kerry). High magnesium alloy chemistry guarantees superior resistance to pitting and intergranular atmospheric attack.
Integrated AS9100-certified 6061-T6 and 7075 components milled to ±0.02mm tolerance for multi-point security locking gear, heavy-duty stainless steel tandem rollers, and anti-lift structural locking blocks.

Our OEM aluminum sliding door extrusions and custom sub-assemblies are specifically designed to address distinct architectural typologies and geographic microclimates found throughout Ireland:
Geographic Focus: Galway, Mayo, Cork, Kerry, Clare, Sligo coastline.
Challenge: Oceanfront homes and luxury resorts face continuous salt air, storm force winds, and high air pressure differentials that blow driving rain through standard slider tracks.
OEM Solution: We supply heavy-duty Lift & Slide patio door systems featuring 5083 marine-grade sub-sills, stainless steel roller tracks, and Qualicoat Seaside certified powder coatings. When closed, the drop-down compression seal drops firmly onto the track, creating a hermetic seal against 1,000+ Pa driving rain.
Geographic Focus: Greater Dublin Area (Docklands, Sandyford, Grand Canal), Limerick City, Cork Docklands.
Challenge: Urban residential schemes require maximum acoustic insulation (R'w + Ctr ≥ 38 dB) to suppress traffic noise, ultra-slim sightlines for maximum daylighting, and strict fire-rated architectural trim integration.
OEM Solution: Minimalist ultra-slim interlock profiles with a visible sightline of only 20mm. Multi-cavity thermal chambers accommodate acoustic laminated glass units up to 52mm thickness while maintaining seamless structural integrity up to 3.5-meter panel heights.
As Ireland advances toward its 2030 climate action targets, the building envelope sector is undergoing rapid evolution. Key industry trends driving OEM procurement include:
Irish green building tenders (LEED & BREEAM certified projects in Dublin) increasingly require environmental product declarations (EPDs). Our factory utilizes high-ratio scrap recycling loops and solar-powered smelting, lowering embedded carbon to <4.0 kg CO2/kg Al.
Universal Design guidance under Irish Building Regulations Part M requires seamless indoor-to-outdoor transition without step hazards. Our custom extrusions include zero-step flush subterranean drainage sills with concealed stainless steel grates.
High-end Irish residential builds are transitioning to motorized large-span sliders. We pre-mill internal wiring channels, drive-shaft housings, and concealed magnetic sensors directly into the OEM profile sections during CNC fabrication.
Rooted in a family metals group heritage operating since 1972, HAQ Aluminium represents a globally competitive manufacturing center combining raw billet extrusion, die design, precision machining, and surface finishing under a single 100% controlled quality umbrella.
Clear technical guidance for window manufacturers, facade engineers, and architectural buyers importing OEM aluminum patio door extrusions into Ireland.
Our OEM sliding patio door profiles feature multi-chambered thermal breaks utilizing 24mm to 34mm PA66 GF25 (25% glass fiber reinforced polyamide) insulation bars. When assembled with double Low-E argon-filled or triple glazing units (Ug ≤ 0.6 W/m²K), the total overall system window U-value (Uw) comfortably achieves between 0.78 and 0.95 W/m²K, fully satisfying Part L requirements for new builds and deep energy retrofits across Ireland.
For coastal zones (within 10km of the Irish coast), we recommend our Qualicoat Seaside grade electrostatic polyester powder coating. Applied over a chromate-free zirconium pre-treatment line, we guarantee a minimum coating thickness of 60 to 80 microns. This finish passes 2,000 hours of acetic acid salt spray (AASS) testing without blistering or filiform corrosion, available in all standard RAL colors (including popular Irish architectural shades like RAL 7016 Anthracite Grey, RAL 9005 Jet Black, and RAL 9016 Traffic White).
Upon receiving your 2D DXF or 3D STEP CAD drawings, our engineering team performs an extrudability and wall-thickness analysis within 24 hours. Die fabrication takes 10 to 15 working days. We then produce first-article profile samples, perform dimensional and hardness checks, and express-courier the sample extrusions to your office in Ireland for final sign-off before commencing full production runs.
Our standard MOQ is driven by alloy billet batch size—typically 500 kg to 1,000 kg per profile section for custom shapes. For standard catalog profiles or trial die orders, we offer flexible volume terms. Orders can be combined into consolidated full container loads (FCL 20ft/40ft) or LCL crated shipments depending on your factory's stock cycle.
Yes. In addition to long bar extrusions (typically standard 5.8m or 6.0m lengths for container fitting), our AS9100 CNC machining center provides complete fabrication services: precision miter cutting, corner cleat punching, drainage slot milling, handle/lock gear mortising, and pre-inserted EPDM gaskets. This allows Irish fabricators to receive ready-to-assemble kit packs, reducing local workshop labor costs significantly.
Yes. All raw material shipments are issued with EN 10204 Type 3.1 Mill Test Certificates verifying alloy chemical composition and mechanical tensile/yield properties. Our manufacturing operations comply with EN 15088 (aluminum structural products for construction), facilitating your CE and UKCA marking certification for finished window and door assemblies marketed in Ireland and the UK.
