Top 10 Aluminium Double Glazed Windows Supplier & Exporter

Every window and door series destined for Australia undergoes independent NATA-accredited laboratory test protocols. We test for deflection under structural design wind pressure, air infiltration, water penetration resistance, and ultimate limit state pressures pursuant to AS 2047. Furthermore, glass types, thicknesses, and safety toughening or laminating comply directly with human impact regulations outlined in AS 1288. Comprehensive laboratory certificates and engineering schedules accompany all container shipments for direct sign-off by local private certifiers and municipal building surveyors.

Yes. With the implementation of the revised New Zealand Building Code Clause H1 (Energy Efficiency), thermal envelope targets mandate significantly lower U-values for vertical fenestration. DERCHI provides thermally broken aluminium profiles paired with double and triple-glazed units utilizing high-performance double-silver Low-E coats, warm-edge spacers, and pure argon fills, achieving system U-values down to 1.4 W/m²K or lower. Pre-production thermal modeling and schedule calculations are coordinated with your project's facade consultants prior to profile extrusion.

For beachfront developments, coastal salt mist represents the primary failure point for standard zinc alloy mechanisms. We equip our export assemblies with 304 or 316-grade austenitic stainless steel friction stays, rollers, hinges, and multipoint lock tongues. Additionally, our aluminium extrusions receive marine-grade electrostatic powder coating complying with Qualicoat Class 2 / AAMA 2604/2605 specifications, or deep hard-anodized coatings (>25 microns) rated for over 3,000 hours of continuous neutral salt spray exposure.

Production lead time typically ranges between 25 and 35 business days following final architectural shop-drawing sign-off and glass build confirmation. Ocean transit from our Foshan facility via Guangzhou or Shenzhen ports ranges between 13 to 22 days to major Oceania destinations (Sydney, Melbourne, Brisbane, Auckland) and 18 to 30 days to Pacific island hubs. All cargo is crated in fully enclosed, fumigated, forklift-accessible timber cases, complete with impact desiccant packages to eliminate moisture sweat during equatorial maritime transit.

Absolutely. Our engineering department operates fully in AutoCAD, Revit, and BIM workflows. We generate detailed opening schedules, structural sub-frame tie-in details, perimeter flashing interfaces, and water weep layouts directly from your architectural elevations. For large-scale developers and long-term distributor partners, our R&D center can design and cut dedicated extrusion dies to establish bespoke proprietary aesthetic profiles for brand-exclusive systems.
