Aluminium Works & Fenestration
Engineered fenestration and structural framing systems fabricated from architectural alloy 6063-T6. From heavy-cycle commercial entrance doors and slim-profile thermal break windows to aerodynamic weather louvers and modular sub-grid assemblies, ANEXA delivers unmatched dimensional precision and weather-tight performance.
Aluminium Door Systems
High-traffic commercial, institutional, and residential entrance doors engineered with heavy-wall extruded aluminium sections. Configurations include heavy-duty pivot doors, slide-and-fold (bi-fold) partitions, automatic sensor sliding doors, and slim-profile casement swing entries designed to handle continuous operating cycles without sagging or corner joint failure.
- Heavy-gauge 6063-T6 corner-cleated profiles with hydraulic crimped joints for structural rigidity.
- European multi-point locking mechanisms providing anti-lift and forced-entry security resistance.
- Heavy-duty concealed overhead door closers, floor springs, and magnetic drop-seal acoustic sills.
- Continuous dual-fin EPDM weather gaskets eliminating air leakage and water ingress at threshold levels.
Aluminium Window Systems
Advanced architectural window fenestrations covering casement side-hung, top-hung ventilators, sliding, tilt-and-turn, and heavy-duty lift-and-slide patio formats. Engineered with precision polyamide thermal breaks, multi-cavity chambering, and slim sightlines to deliver high thermal insulation, sound attenuation, and maximum outdoor visual connectivity.
- Polyamide PA66 GF25 thermal break barriers eliminating internal frame condensation and heat transfer.
- Acoustic glazing pockets accommodating double and triple-glazed units up to 42mm overall thickness.
- Stainless steel friction stays, heavy-duty tandem rollers, and ergonomic aluminum die-cast handles.
- Tested to resist hurricane-force wind pressures (IS 875) and driving rainwater penetration (AAMA/EN standards).
Extruded Aluminium Louvers
Engineered ventilation and architectural screening assemblies manufactured from custom extruded profiles. Configured in aerofoil sun-blades, storm-proof double-drainage blades, continuous chevron profiles, and acoustic sound-dampening louvers for mechanical plant rooms, generator enclosures, and parking podium facades.
- Calibrated aerodynamic free-air discharge areas (45% to 65%) preventing chiller airflow starvation.
- Double and triple-bank rain-trap geometry blocking horizontal water entry during monsoons.
- Hidden clip-bracket mounting onto vertical mullions for seamless, unpenetrated continuous runs.
- Integrated rear stainless steel SS-304 bird guards and insect screen wire cloth meshes.
Aluminium Commercial Shopfronts
Heavy-duty, wide-span framing systems tailored for retail store entries, luxury automobile showrooms, shopping mall frontages, and corporate reception zones. Designed with reinforced structural mullions capable of holding floor-to-ceiling panoramic glass panels with minimal framework obstruction and maximum merchandise visibility.
- Deep-pocket center-glazed and flush-glazed framing accommodating heavy laminated safety glass.
- Internal structural steel reinforcement tubes inserted inside mullions for expansive vertical spans.
- Seamless integration with automated glass sliding doors, panic exit devices, and access control locks.
- Finished in premium architectural Qualicoat-certified powder coating or deep metallic anodizing.

Modular Aluminium Framing Systems
Specialized sub-structure grid frameworks and heavy carrier rails engineered to anchor secondary facades, exterior feature fins, double-skin envelopes, and architectural panel claddings back to the primary reinforced concrete building structure. Designed to absorb thermal movement and construction slab variances without transferring stress to finished elements.
- Structural extruded T-profiles, L-angles, and box channels in structural 6063-T6 / 6061-T6 temper.
- 3D-adjustable slotted brackets absorbing civil edge casting out-of-plumb deviations up to ±30mm.
- ETAG-certified high-tensile chemical anchors and stainless steel A4/316 isolation hardware.
- Thermal isolator pads installed between concrete slabs and brackets to halt thermal bridging.
