Engineered for Hurricane Resistance, Structural Thermal Efficiency, and High-Traffic Architectural Performance.
Founded in 2015, Chengdu Zenit Window & Door Co., Ltd. operates a state-of-the-art 25,000-square-meter manufacturing facility. Backed by 11 years of deep industry expertise and 8 years of dedicated global trade experience, the company consistently achieves an annual export turnover exceeding $26 million USD. Our primary export footprints span across North America, Australia, and Western Europe, positioning Zenit as the preferred strategic OEM/ODM factory partner for high-end residential home builders, architectural master contractors, facade engineering firms, and international building material wholesalers.
Quality assurance and structural integrity are integrated into every phase of production. Our internal quality control system is executed by a specialized team of 35 senior inspectors who perform rigorous air permeability testing, dynamic water tightness checks under intense pressure cycles, and structural frame corner strength evaluations. Supported by a robust network of over 600 vetted supply chain partners, Zenit delivers comprehensive customization options—ranging from ultra-low thermal break extrusion profiles and custom anodized architectural finishes to triple-pane soundproof laminated glass assemblies. Driven by an active R&D division of 42 system engineers, we successfully released 50 new architectural door and window systems over the past year alone, staying ahead of international building energy codes and design trends.
Inside Zenit’s 25,000 m² Advanced Fabrication Facility: From Raw Aluminum Alloys to Certified Architectural Door Systems


















Customized Exterior Aluminum Door Engineering tailored to regional climates, safety codes, and aesthetic demands.
Designed specifically for Florida, the Caribbean, and Southeast Asian typhoons. Utilizing high-tensile 6063-T6 aluminum alloys and SGP multi-layer laminated impact glass. Tested to withstand wind-load pressures exceeding 5000 Pa (ASTM E1886/E1996 standards), preventing structural deflection during major storm events.
Incorporating polyamide PA66 GF25 thermal breaks with multi-cavity insulation inserts. Zenit exterior aluminum doors achieve overall U-values as low as 0.8 to 1.2 W/m²K. Combined with Argon-filled Low-E triple glazing, these systems dramatically reduce HVAC power requirements in Northern Europe and North America.
Featuring heavy-duty European multi-point gear locking mechanisms, integrated smart biometric access control (fingerprint/keypad/smart app), and hidden reinforced heavy-duty hinges capable of supporting door sash weights up to 400 kg. Engineered for high-traffic hotels, retail malls, and luxury modern villas.
The global exterior fenestration market is undergoing a structural transition toward digital automation, circular economy raw materials, and extreme thermal resilience. As a pioneering manufacturer based in China with global trade reach, Chengdu Zenit Window & Door Co., Ltd. continuously invests in next-generation R&D roadmaps to ensure our B2B partners maintain competitive differentiation in local markets.
Future architectural aluminum outside doors are no longer passive physical barriers; they are intelligent building components. Zenit’s latest system R&D integrates low-voltage electrochromic smart glass directly powered by concealed wiring within the aluminum frame. Users can modulate tint density, solar heat gain coefficient (SHGC), and privacy settings via automated building management systems (BMS) or mobile applications. Electric lift window-door hybrid units and motorized garage portals feature automatic rain-sensing closing triggers and obstacle-detection safety loops.
Traditional single-chamber thermal break profiles are quickly being replaced by multi-chamber structural polyamide strips (PA66 GF25 reinforced with 25% glass fiber). In our latest 2024–2025 product iterations, Zenit engineers have integrated localized nanoporous aerogel insulation within the extrusions. This innovation reduces frame thermal bridging by up to 35%, ensuring compliance with strict European Energy Performance of Buildings Directive (EPBD) standards and US Energy Star v7.0 specifications.
To support global Net-Zero initiatives, Zenit is prioritizing prime 6063-T6 aluminum alloys incorporating high percentages of post-consumer recycled metal smelted using clean hydroelectric energy. Furthermore, our surface finishing lines utilize eco-friendly chromate-free pretreatment processes and high-durability AkzoNobel/PPG fluorocarbon (PVDF) powder coatings guaranteed against UV degradation, chalking, and salt-spray corrosion for over 25 years.

Custom Front Entry Doors, Unitized Curtain Walls, Heavy-Duty French Doors & Specialized Architectural Louvres.
In-Depth Answers for Architectural Engineers, Contractors, and Global Importers
Standard solid aluminum is a highly conductive metal, meaning heat and cold easily transfer through the frame, causing energy loss and condensation issues. Thermal break aluminum profiles feature an engineered non-conductive barrier—typically Polyamide PA66 GF25—inserted between the interior and exterior aluminum sashes. This structural break dramatically lowers the thermal conductivity (U-value), prevents interior frame sweating, improves acoustic isolation, and allows buildings to pass modern energy compliance codes like NFRC and Title 24.
Zenit operates a dedicated R&D division of 42 system engineers who work directly with client CAD architectural drawings and BIM models. We provide shop drawing generation, structural wind-load calculation modeling, custom profile extrusion matrix engineering, and bespoke color-matching (RAL codes, anodized grain, metallic fluorocarbon). Our 35 QC inspectors verify every detail from extrusion tolerances to glass sealant adhesion prior to international container loading.
Our hurricane impact door systems are engineered using heavy-wall 6063-T6 aluminum alloys and double/triple glazed units with interlayer options including SentryGlas (SGP) or high-flex PVB films. These systems undergo testing according to ASTM E1886 / E1996 and Florida Building Code TAS 201/202/203 standards to resist missile impact, cyclic pressure loading, and severe wind-driven water intrusion.
Standard production lead time ranges between 25 to 35 business days depending on custom extrusion requirements and anodizing finishes. To prevent transit damage, products undergo a 5-layer packaging process: protective protective film on profiles, corner guards, EPE foam wrapping, fully enclosed fumigated wooden crates or steel transport racks, and moisture-absorbing desiccant placement inside container shipments.
Yes. Our intelligent electric lift window-doors and motorized garage/entrance doors are compatible with major home automation protocols (Zigbee, Z-Wave, KNX, RS485). They feature hidden linear actuators, electric multi-point locks, proximity sensors, and remote app integration for seamless modern living.
