Explore our export-grade alloy plates, custom extruded sections, and specialized machine components manufactured under ISO 9001 and AS9100 quality control systems. Fully compatible with European and Asian textile machinery OEMs.
In modern textile manufacturing facilities across Sri Lanka—spanning high-speed air-jet weaving, rapier looms, and circular knitting plants—machinery components endure continuous cyclic stresses, high angular velocity, and aggressive environmental exposure. Choosing the appropriate aluminum extrusion alloy and heat treatment temper directly governs machinery uptime, vibration harmonics, yarn friction coefficients, and long-term energy consumption.
During high-speed warping and weaving operations exceeding 800 to 1,200 picks per minute (PPM), traditional heavy steel beam barrels generate excessive rotational inertia. This inertia increases power consumption on drive motors during acceleration and decelerating stop cycles, while imparting elevated strain on bearings.
Our engineered 6061-T6 and 6082-T6 aluminum extrusion beam barrels provide a high strength-to-weight ratio (yield strength ≥ 260 MPa). By replacing legacy steel components with heat-treated aluminum extrusions, textile engineers reduce rotational inertia by up to 42%, directly cutting kilowatt-hour (kWh) usage per loom pick and extending bearing life cycles.
The table below provides empirical metallurgical comparison data for mechanical engineers and mill technical managers specifying extrusion profiles and aluminum plates for garment automation and weaving machinery.
| Alloy & Temper | Tensile Strength (MPa) | Yield Strength (MPa) | Corrosion Resistance | Machinability / Weldability | Primary Textile Machinery Application |
|---|---|---|---|---|---|
| 6063-T6 | 215 - 245 | 170 - 200 | Excellent | High / Excellent | Heald frames, reed profiles, structural machine guards, modular conveyor tracks. |
| 6061-T6 | 290 - 330 | 240 - 275 | Very Good | Excellent / Good | Loom beam barrels, main drive support arms, high-load warp beams, structural mounting plates. |
| 6082-T6 | 310 - 350 | 260 - 290 | Very Good | High / Good | High-tension weaving beams, heavy-duty machinery chassis, stress-bearing crossbeams. |
| 5083-H116 | 305 - 380 | 215 - 280 | Superior (Marine Grade) | Moderate / Excellent | Wet processing units, dyeing machine tanks, chemical-exposed side plates, steaming frames. |
| 5052-H32 | 210 - 260 | 130 - 180 | Superior (Chemical) | Good / Excellent | Yarn guide covers, wet process hoods, anti-corrosive machine shrouds, deep-drawn enclosures. |

Sri Lanka’s apparel ecosystem demands localized engineering solutions. From the tropical coastal humidity in Export Processing Zones (EPZs) to high-speed automated sewing and knitting lines, HAQ Aluminium extrusions are customized for local operational realities.
Weaving facilities operating Tsudakoma and Toyota air-jet looms require precision warp beam barrels and extruded reed rails that maintain zero deflection under continuous high warp tension. Our 6061-T6 dynamic-balanced extruded tubes prevent yarn breakage, ensuring uniform fabric tension during 24/7 continuous weaving cycles.
Textile dyeing, bleaching, and washing equipment operates under aggressive alkaline and acidic liquid conditions combined with ambient relative humidity exceeding 85% RH. Utilizing Marine-Grade 5083-H116 and 5754 aluminum plates with 20-micron anodization eliminates rust risk and liquid chemical degradation, outlasting conventional coated steel panels by 3x.
Modern garment assembly plants integrating automated overhead trolley lines require lightweight, high-rigidity structural track profiles. Our custom slotted 6063-T5 aluminum extrusions facilitate rapid modular assembly, reducing overhead installation loads on factory roof trusses while providing ultra-smooth, low-friction trolley sliding surfaces.
Sri Lanka’s apparel export sector is rapidly transitioning toward Industry 4.0 automation, high-value technical textiles, and green energy compliance. Key drivers reshaping machinery extrusion procurement include:
Backed by over five decades of metallurgical manufacturing experience (est. 1972), HAQ Aluminium provides an end-to-end integrated production ecosystem—from raw billet casting and custom die sinking to 5-axis CNC machining, anodizing, and powder coating.
Send CAD drawings (DXF/STEP) or physical sample sections. Our tooling engineering division manufactures precision extrusion dies in 10-15 working days with first-article sample verification.
Every extrusion batch undergoes rigorous SPECTRO chemical alloy composition analysis, WebE-hardness testing, dimensional tolerance checking, and surface roughness verification.
Our automated chromate-free pre-treatment, architectural anodizing, and electrostatic powder coating lines guarantee superior surface wear, electrical insulation, and chemical protection.
Profiles are interleaved with protective non-scratch film, bundled with moisture-barrier kraft paper, and mounted on wooden pallets optimized for 20ft/40ft ocean container shipping to Colombo.
