Send an InquiryDoha's aggressive urbanization—marked by megaprojects in Lusail City, West Bay, Msheireb Downtown, and Al Thumama—demands window framing systems capable of enduring one of the most punishing architectural environments on earth. Custom OEM window frame manufacturing for Qatar requires an intimate understanding of extreme thermal cycling, high ambient solar radiation, sandstorm abrasion, and coastal atmospheric salinity.
Under the Qatar Construction Specifications (QCS 2014) and the energy efficiency criteria set by the Global Sustainability Assessment System (GSAS), standard non-thermally broken aluminum window profiles are no longer viable for commercial or high-end residential applications. Modern facade specifications mandate high-performance extruded aluminum alloys integrated with advanced polyamide thermal break technology.
Technical Insight for Qatar MEP Contractors: Solar irradiance in Doha can drive ambient surface temperatures on dark-finished aluminum window frames past 75°C during July and August. Without engineered thermal barriers and Qualicoat Class 2/3 super-durable coatings, profile degradation, thermal bridging, and severe HVAC energy loss are inevitable.
Our OEM factory extrudes architectural window profiles primarily from virgin-grade 6063-T5/T6 and 6061-T6 aluminum billets. For specialized coastal sub-framing, mullions, and high-load structural brackets, marine-grade 5083-H116 and 5052-H32 plates are sheared and machined to exact tolerances.
| Alloy & Temper | Tensile Strength (MPa) | Yield Strength (MPa) | Recommended Doha Application |
|---|---|---|---|
| 6063-T5 / T6 | 215 - 245 | 170 - 210 | Main window frame extrusions, sliding sashes, casements, and louvers. |
| 6061-T6 | 310 | 276 | Heavy structural curtain wall mullions, transoms, and corner cleats. |
| 5083-H116 | 305 - 380 | 215 | Marine coastal sub-frames, anchor plates, and basement air intake frames. |
| 5052-H32 | 230 | 195 | Architectural window sill flashings, spandrel panels, and decorative trims. |
To comply with GSAS 4-Star and 5-Star thermal envelope metrics, our factory utilizes dual-chamber extruded aluminum profiles mechanically joined via 24mm to 34mm Polyamide PA66 GF25 (25% Glass Fiber Reinforced) insulation strips. This thermal break structure effectively isolates the exterior aluminum casing from the interior ambient air, preventing thermal conductivity across the building envelope and stopping internal frame condensation during peak air-conditioned summer months.
Every district in Doha exhibits unique micro-climatic and architectural demands. OEM manufacturing requires modular tooling options that allow local fabricators and facade contractors to adapt frame depth, glass pocket widths, and sealing gaskets to localized building typologies.
High wind pressures along the Lusail coastline require structural window frames tested to ASTM E330 wind load pressures exceeding 3.0 kPa. We supply heavy-wall 6061-T6 extruded mullions designed for unitized structural glazing systems.
Direct exposure to hyper-saline Gulf air causes rapid oxidation on inferior window treatments. Our 25-micron thick Class 1 anodized finishes and marine-grade 5083 sub-frames prevent filiform corrosion and pitting over decades of operational life.
Retrofitting and new builds in Msheireb require narrow sightline window profiles with high acoustic damping (Rw ≥ 42 dB) to isolate indoor environments from urban traffic noise while preserving traditional Qatari architectural motifs.
Doha's frequent shamal sandstorms deposit microscopic silica particles that compromise standard window brush seals and drainage slots. Our custom OEM window extrusions incorporate triple-stage EPDM vulcanized gasket seals and staggered, pressure-equalized concealed drainage channels that allow water runoff while completely blocking wind-driven sand ingress.
As Qatar advances toward Qatar National Vision 2030, the construction sector is undergoing a structural transition toward decarbonization, embodied carbon auditing, and circular economy compliance. Window frame procurement is no longer driven purely by initial landed cost; life-cycle performance and environmental product declarations (EPD) are paramount.
Traditional polyester powder coatings suffer from chalking and color fading within 3 to 5 years under Qatar's high UV index. The Doha market now mandates Qualicoat Class 2 (Organic Fluorocarbon / Super-Durable Polyester) or Class 3 (PVDF Architectural Coatings). Our factory operates an automated chromate-free pre-treatment line that guarantees coating adhesion for 25 years under ASTM B117 salt spray testing.
With urban density increasing along the C-Ring and D-Ring roads, specifications have shifted from single-glazed 6mm frames to deep pocket 28mm-44mm double and triple acoustic insulated glass units (IGU). OEM manufacturers must produce wider frame depth sections (70mm to 110mm system depths) with reinforced hinge tracks to support glass weights up to 120kg per sash.
Major developers like Qatari Diar and United Development Company (UDC) incentivize suppliers offering low-carbon aluminum billets refined using hydroelectric energy or incorporating up to 75% recycled post-industrial scrap. Our closed-loop manufacturing recycles all extrusion butt ends and machining swarf in-house, significantly lowering the carbon footprint per linear meter of window frame.
Rooted in a 53-year family metallurgical legacy originating in 1972, HAQ Aluminium combines heavy industrial manufacturing power with flexible OEM custom tooling capabilities. Unlike third-party job shops, our fully integrated facility handles die design, billet extrusion, heat treatment ageing, CNC precision machining, and surface finishing under a single unified Quality Management System.
Send DXF or STEP drawings and our tooling division produces custom extrusion dies in 10–15 working days, delivering first-article physical samples for architectural approval before mass production.
Operating multi-press capacity up to 3,500-ton hydraulic presses, we accommodate large-volume project orders for Qatar commercial developments without bottlenecking delivery schedules.
Export packaging features interleaved anti-scratch protective film, water-tight plastic wrapping, and heavy timber crates strapped for efficient 20ft/40ft container shipping direct to Hamad Port, Doha.
Every production batch undergoes mandatory metallurgical and dimensional testing prior to export dispatch:
Yes. All extruded aluminum sections, thermal break PA66 GF25 strips, and architectural surface treatments are engineered specifically to satisfy or exceed QCS 2014 Section 17 (Metalwork) and Section 24 (Finishes). Mill test certificates and independent laboratory test reports accompany every shipment.
Production and fabrication times average 2 to 3 weeks following drawing approval. Direct ocean freight transit to Hamad Port typically takes 12 to 18 days, ensuring a total door-to-port timeline of under 5 weeks for custom extruded batches.
We strongly advise specifying either Qualicoat Class 2/3 super-durable PVDF powder coating or Class 1 (25-micron minimum) anodized finishes. These surface treatments prevent filiform pitting and salt-air oxidation common in humid Gulf maritime environments.
Yes. We specialize in custom OEM tool manufacturing. Under strict Non-Disclosure Agreements (NDA), we develop custom extrusion dies based on your DXF/STEP CAD files, producing exclusive window profile series unique to your company or project.
Our polyamide thermal break window assemblies significantly lower overall building envelope Thermal Transmittance (U-value) down to < 1.3 W/m²K and reduce Solar Heat Gain Coefficients (SHGC). This directly boosts points under GSAS Energy & Water category criteria.
Standard MOQ for custom die profiles is typically 500 kg to 1,000 kg per profile shape. For established contractors and large-scale commercial developments in Doha, we offer batch production programs with staggered container drop-shipments.
