Explore our industrial-grade aluminum systems, custom-engineered for extreme weather durability, acoustic attenuation, and modern architectural aesthetics. All units are factory pre-hung and tested to ISO, CE, and AS2047 structural criteria.
In the contemporary B2B architectural procurement market, Custom OEM Aluminum Double Swing Doors (frequently designated as heavy-duty exterior French doors or double-leaf casement entry systems) represent a critical juncture between structural engineering, thermal performance, and high-end design aesthetics. As commercial developers, general contractors, and fenestration distributors navigate stringent building codes—such as ASHRAE 90.1 energy metrics, AS2047 structural displacement thresholds, and European CE EN 14351-1 standards—partnering with an authentic Original Equipment Manufacturer (OEM) becomes paramount.
Aluminum alloy profiles, specifically extruded 6063-T5 and 6063-T6 temper grades, have superseded traditional timber and unplasticized polyvinyl chloride (uPVC) in modern double swing door applications. This transition is driven by aluminum's exceptional tensile strength-to-weight ratio, structural resistance against wind load deflections (up to 4500 Pa), superior resistance to UV degradation, and compatibility with complex multi-point mortise locking gear. Furthermore, the evolution of polyamide (PA66GF25) thermal break technology has eliminated historic thermal conductivity drawbacks, positioning aluminum double swing systems as energy-efficient solutions for Passive House and LEED-certified building envelopes.
Understanding the engineering micro-components of a custom double swing aluminum entrance system allows procurement managers to differentiate between standard grade residential fenestration and commercial OEM solutions built for high-traffic, harsh climate exposure.
Our OEM profile wall thickness ranges strictly between 2.0mm and 3.0mm for structural door sashes. We incorporate 24mm to 34mm PA66 nylon thermal break strips reinforced with 25% glass fiber, stopping thermal bridging and eliminating frame condensation under extreme temperature differentials (ΔT > 40°C).
Equipped with Insulated Glass Units (IGU) ranging from double-pane (6mm + 12Ar + 6mm) to triple-pane acoustic laminated glass filled with 95% pure Argon gas. Warm-edge Swisspacer bars and Low-E coatings reduce overall U-Factors down to 1.1 W/m²K while boosting Acoustic STC up to 42 dB.
Integrates heavy-duty German hardware architecture (Siegenia, Hoppe, GU) alongside 316 marine-grade stainless steel adjustable flag hinges. The active sash features a 5-point key locking mechanism while the inactive slave sash utilizes concealed top and bottom flush bolts for absolute perimeter tightness.
Structural reliability in double swing doors depends entirely on corner joint rigidity. Unlike standard screw-fastened frames, our factory utilizes heavy-duty hydraulic corner crimping machines coupled with dual-component structural corner adhesives (German Weiss Cosmofen).
This automated fabrication protocol ensures millimetric diagonal tolerances, preventing door sash sagging over decades of heavy commercial usage while maintaining IP65 equivalent air and water tightness ratings.
Water infiltration is a primary cause of structural damage in exterior door openings. Our double swing systems employ continuous ternary ethylene-propylene (EPDM) sealing gaskets combined with vulcanized molded corner joints.
The bottom sill incorporates a multi-tier threshold barrier featuring integrated drainage channels and drop-down automatic acoustic seals, ensuring zero water penetration under dynamic wind-driven rain tests up to 700 Pa.

As global supply chains realign towards sustainable practices and smart building integration, B2B fenestration buyers must align their procurement strategies with critical technological shifts emerging over the next decade.
Modern luxury residential projects demand maximum glass area with minimal frame interference. Sourcing trends show a 40% YoY increase in demand for narrow-stile double swing doors (interlock profiles under 30mm) that retain full structural integrity through hidden steel reinforcers and heavy-duty concealed hinges.
Traditional mechanical keyways are rapidly evolving into electro-mechanical smart locking ecosystems. Commercial OEM contracts increasingly specify factory-prewired door frames compatible with motorized multi-point locks, facial recognition sensors, RFID keypads, and building management system (BMS) integration.
European and North American markets are introducing embodied carbon penalties. Future-proof factories are adopting post-consumer recycled aluminum billets (using hydro-powered smelting process) reducing embodied carbon emissions from 18kg CO2/kg to under 4.0kg CO2/kg without altering metallurgical strength.
Established in 1993 in Dali Town, Foshan City—China's global capital of aluminum extrusions—Window Wurx Industry Co., Ltd. has evolved into a premier OEM/ODM manufacturer specializing in custom windows, doors, sunrooms, and curtain wall systems for international export markets.
Long-distance maritime logistics present significant risks to pre-finished aluminum surfaces and glass integrity. Our factory implements a rigid 5-layer packaging standard:
