Top China Aluminium And Glass Window Manufacturers & Factories

We do not produce generic one-size-fits-all products. Each production lot is custom-configured to the statutory building requirements of the project site. For North American projects, we supply official NFRC simulation and physical test reports detailing thermal transmittance (U-factor), Solar Heat Gain Coefficient (SHGC), and Visible Transmittance (VT) in compliance with IECC and ENERGY STAR® v7.0 zones. For structural and wind-driven rain codes, our systems comply with NAFS / AAMA / WDMA / CSA 101/I.S.2/A440 ratings. In hurricane regions (Florida and the Gulf Coast), we specify ASTM E1886/E1996 tested assemblies featuring laminated glass with Kuraray SentryGlas (SGP) or high-grade PVB interlayers capable of passing missile impact and 9,000 cyclic wind cycles. For Australia, our extrusions and assemblies are strictly tested against AS2047 and glazing AS1288 standards.

We use exclusively 100% virgin aluminium billets conforming to architectural 6063-T5 and 6063-T6 temper specifications (chemical composition: Si 0.20–0.60%, Mg 0.45–0.90%, Fe ≤ 0.35%). We never allow low-grade post-consumer scrap remelts that compromise tensile strength or cause surface blistering under anodizing or PVDF coatings. Wall thicknesses strictly fulfill or exceed 1.4mm to 2.0mm for residential windows and 2.0mm to 3.0mm+ for heavy-duty commercial sliding doors and curtain wall transoms. Extrusions adhere to high-precision DIN EN 12020-2 / GB 5237 high-accuracy standards. Surface finishing options include Qualicoat-certified AkzoNobel or PPG architectural powder coatings (guaranteed 10 to 15 years against chalking and fading) and AAMA 2605-compliant 70% Kynar 500 fluorocarbon (PVDF) three-coat systems for severe coastal exposure.

Transit damage is entirely engineered out through an industrial crating protocol. All frames are clad with protective anti-scratch peel-off tape, corners are armored with impact-absorbing high-density polyethylene protectors, and individual units are wrapped in multi-layer pearl foam and waterproof vacuum-sealed shrink film. For containerization, units are packed into fully enclosed fumigated plywood or steel-reinforced A-frame crates compliant with ISPM 15 standards. Crates are loaded using heavy overhead gantry cranes, blocked, and strapped within 40ft HQ dry van or open-top containers with heavy ratcheted polyester tie-downs. We regularly ship multi-million dollar architectural packages into ports such as Los Angeles, Vancouver, Long Beach, Sydney, and Rotterdam with a verified 99.8% damage-free delivery track record.

Yes. Our engineering division works fluidly with both metric systems and imperial feet/inches. We regularly produce shop drawings incorporating standard North American 1-3/8 inch or 1-1/2 inch nail fin (flange) extrusions for wood-frame construction, brick mold accessories for masonry cavity walls, and flush fin retrofits for existing aluminum/wood replacements. Prior to casting or cutting a single bar of aluminum, we draft complete shop drawings detailing full cross-sections, head, jamb, sill flashings, and anchoring details. Production begins only after the client's project architect, GC, or facade consultant formally signs off on the shop submittals.

Our standard manufacturing turnaround is 25 to 35 calendar days following shop drawing sign-off and receipt of the project deposit (custom die extrusion or specialized tinted low-iron Low-E coatings may add 7 to 10 days). Standard commercial terms are 30% to 50% deposit upon formal order contract confirmation, with the balance payable upon completed quality audit, video inspection, and submission of the ocean bill of lading (B/L) copy. We welcome third-party international quality assurance inspections (such as SGS, Bureau Veritas, or TÜV Rheinland) at our Foshan manufacturing base prior to container sealing.

We provide a comprehensive 10-year structural warranty on our aluminum frames and surface coatings, alongside a 5-year hermetic warranty on insulated glass units against seal failure or internal fogging. All hardware systems (Siegenia, Roto, Hoppe, or our proprietary patented locks) are tested to 50,000 to 100,000 cycles and backed by a 5-year mechanical warranty. Every exported shipment includes an additional 2% to 3% buffer of critical hardware components, gaskets, and roller bearings free of charge. In the rare event of damage or component defect, express replacement parts are dispatched via DHL/FedEx air freight at our expense within 48 hours.
