Direct factory supply manufactured to AS2047, CE, and ISO9001 standards for residential, commercial, and resort developments across Sri Lanka.
A comprehensive technical evaluation for architects, structural engineers, developers, and trade buyers in Colombo, Galle, Kandy, and coastal resort sectors.
Sri Lanka's rapid infrastructure growth across Greater Colombo, the Southern Coast (Galle, Mirissa, Tangalle), and the Central Highlands (Kandy, Nuwara Eliya) has elevated architectural demands. Traditional timber fenestration suffers from severe warping and termite degradation due to constant relative humidity exceeding 80%. Non-thermal standard aluminum profiles, while widespread in low-cost construction, act as direct heat conductors, transferring solar radiation into air-conditioned interior spaces and driving energy bills up significantly.
Modern luxury residential high-rises along Colombo's Marine Drive and eco-resorts in Bentota now mandate high-performance fenestration systems. These systems must combine acoustic insulation (against urban traffic and monsoon wave action), structural integrity against cyclonic wind pressure (N6 wind pressure ratings exceeding 4500 Pa), and extreme salt-spray resistance to prevent pitting corrosion.
Sri Lanka experiences dual monsoons (South-West and North-East). Our thermally broken profiles feature triple-sealed EPDM gasket systems and concealed drainage channels with anti-backflow valves, guaranteeing zero water penetration up to 700 Pa differential pressure.
Coastal developments within 5km of the Indian Ocean require specialized surface coatings. We apply 3-coat PVDF (Polyvinylidene Fluoride) coatings or 25-micron anodized finishes certified to Qualicoat Class 2 standards, resisting salt-spray fog for over 3,000 hours.
Combining heavy-duty 6063-T5 thermally isolated profiles with double-glazed insulated units featuring laminated interlayers (6mm Low-E + 12A/20A Argon + 6mm Clear / Laminated) reduces ambient urban sound transmission by up to 42 decibels.
Quantitative performance metrics comparing China direct factory specs against standard local Sri Lankan market offerings.
| Performance Parameter | Our Factory Direct Specs (Thermal Break) | Standard Local Sri Lanka Profiles | Architectural Benefit / Impact |
|---|---|---|---|
| Raw Material Alloy | Primary 6063-T5 Virgin Aluminum Ingot | Recycled / Secondary Grade Aluminum | Higher tensile strength, precise wall tolerances, superior finish longevity. |
| Thermal Isolator | PA66-GF25 Polyamide Structural Nylon (24mm–34mm) | None or Low-Grade PVC Strips | Prevents frame thermal expansion cracking; reduces U-factor to <1.8 W/m²K. |
| Glazing Capability | 5mm+18A/20A+5mm Double/Triple Tempered Low-E | 5mm–8mm Single Sheet Float Glass | Cuts radiant heat ingress; eliminates inner surface glass sweating/condensation. |
| Wind Pressure Rating | Service Pressure >4500 Pa (AS2047 N6 / CE Class C5) | 1200 Pa – 1800 Pa Standard | Engineered for Colombo coastal high-rise curtain walls & hilltop wind loads. |
| Hardware Integration | German Siegenia / Hoppe / GU Multi-point Locking | Generic Single-latch Friction Hinges | Enhanced forced-entry security, smooth operation, 50,000+ cycle durability. |
| Insect Protection | 304/316 Marine Stainless Steel High-Clarity Screen | Nylon or Soft Fiber Mesh | Protects against mosquitoes & insects; resists pet claw damage and salt rust. |
Custom fenestration solutions matched specifically to regional geography, microclimates, and architectural topologies.
For high-rise residential towers exposed to high wind pressures and city noise, our ultra-slim frame thermally broken tilt and turn windows provide secure, micro-ventilated airflow without compromising structural safety or acoustic damping.
In high salt-mist environments along the Southern coast, our minimal sliding doors and heavy-duty gas-strut awning windows feature 316-grade stainless steel rollers and hardware paired with 25µm anodized aluminum to withstand harsh marine decay.
High-altitude locations experience significant diurnal temperature shifts and high moisture. Thermal break insulation prevents indoor frame condensation while holding heat inside during cool highland nights, reducing reliance on electric heating.
Eliminating middleman markups by connecting Sri Lankan developers directly with China's top-tier fenestration production lines.
Leveraging over 30 years of manufacturing heritage, our automated production base utilizes high-precision CNC double-head cutting saws, automatic corner crimping machines, and robotic sealant application lines. Every aluminum frame is extruded strictly using virgin 6063-T5 billets, ensuring superior structural stability and flawless surface finishing.
Our full supply chain capability spans custom aluminum profile extrusion, thermal strip insertion, powder coating/PVDF treatment, insulated glass unit (IGU) assembly, and rigorous water-tightness testing prior to export packing.
Direct oceanic shipping routes connect our coastal manufacturing hub in China directly to the Port of Colombo (FCL & LCL shipping options available). Our dedicated international trade team handles all shipping manifests, certificates of origin, CE/AS2047 test documentation, and customs clearance paperwork.
Whether you require direct sea shipment for volume multi-family projects or consolidated container deliveries for custom boutique villas, we provide factory-direct pricing that lowers total procurement costs by 25%–40% compared to local sourcing.
Addressing essential technical, logistical, and custom clearance queries for Sri Lankan architects, builders, and importers.
Standard aluminum is a metal conductor that transfers intense solar heat directly into air-conditioned interior spaces. A thermally broken profile uses a low-conductive polyamide strip (PA66-GF25) to isolate the exterior and interior aluminum extrusions. This stops thermal bridging, keeping interior surfaces cool, reducing AC power consumption, and preventing surface sweating during humid mornings.
Our window and door systems are fully tested and certified to international standards including AS2047 (Australian Standard for Windows and Doors in Buildings), CE (European Conformity), and ISO9001. Performance test reports cover air infiltration resistance, water penetration resistance (up to 700 Pa), structural wind pressure capacity (up to 5000 Pa), and acoustic STC ratings.
For coastal projects within 5 km of the ocean, we recommend specialized surface treatments: either 3-coat PVDF fluoropolymer coating or 25-micron high-depth anodization certified under Qualicoat rules. Combined with 304 or 316 marine-grade stainless steel hardware and EPDM weatherstripping, our systems resist rust, surface pitting, and salt mist degradation for decades.
Production cycles typically take 25 to 35 days depending on profile customization and glass specifications. Sea freight transit from major Chinese shipping ports (Ningbo, Shanghai, Shenzhen) to the Port of Colombo takes approximately 12 to 16 days. Units are securely crated in steel-framed fumigated wooden boxes designed for safe unloading by local crane or forklift operators.
Yes. Every order is 100% custom-engineered based on your project's rough opening dimensions and structural requirements. Our engineering team prepares detailed CAD shop drawings detailing profile cross-sections, glass build-ups, anchor points, and drainage details for approval prior to raw material extrusion and cutting.
Purchasing direct from our Chinese manufacturing facility eliminates multiple layers of local distributor, dealer, and agent markups. Even after factoring in oceanic sea freight, insurance, and local Sri Lanka import tariffs, developers typically achieve 25% to 40% overall cost savings while acquiring significantly higher-tier extrusions, double Low-E glass, and premium German hardware.
