Explore our engineering-grade OEM/ODM fenestration solutions customized for international architectural compliance, structural resilience, and high-traffic performance.
Chengdu Zenit Window & Door Co., Ltd. represents the peak of industrial manufacturing rigor, combining decade-long technical expertise with a global footprint across tier-one architectural markets.
Founded in 2015, Chengdu Zenit Window & Door Co., Ltd. operates a 25,000-square-meter manufacturing facility. Backed by 11 years of industry expertise and 8 years of global trade experience, the company achieves an annual export turnover of $26 million. Our primary export markets cover North America, Australia, and Western Europe, catering to residential home builders, architectural contractors, and building material wholesalers.
Quality control is managed by a team of 35 inspectors who perform rigorous air permeability testing, water tightness checks, and frame corner strength evaluations. Supported by over 600 supply chain partners, Zenit delivers comprehensive customization options including thermal break profiles, custom anodized finishes, and triple-pane soundproof glass. Driven by an active R&D division of 42 engineers, we released 50 new architectural window systems over the past year.
Analyzing the evolution of urban building envelopes, stringent energy mandates, and high-traffic architectural demands across North America, Europe, and Australasia.
Modern commercial developments require low U-factors and optimized Solar Heat Gain Coefficients (SHGC). Standard non-thermal aluminum profiles are no longer viable under North American IECC or European EPBD frameworks. Polyamide thermal breaks (PA66-GF25) are mandatory to mitigate linear thermal bridging and prevent interior condensation.
Storefront entrances endure severe cycle rates, physical wear, and potential forced entry risks. Enterprise-grade commercial doors demand 6063-T6 aluminum extrusions with wall thicknesses up to 3.0mm, heavy-duty continuous offset pivots, continuous gear hinges, and multi-point deadbolt locking options compliant with ANSI/BHMA standards.
Coastal and hurricane-prone geographical zones require validated impact performance. Aluminum storefront profiles engineered with SGP (SentryGlas®) laminated interlayers withstand high wind speeds and missile impact tests (ASTM E1886/E1996 and Florida Building Code TAS 201/202/203 protocols) without losing structural seals.
Pioneering advanced architectural fenestration technologies, sustainable material science, and intelligent building system integration.
Integration of electro-magnetic latches, motorized push-pull operators, hidden sensor headers, and biometric access technology. Zenit’s OEM engineering team optimizes aluminum extrusion door stiles to conceal wiring channels, smart locks, and sensor systems without compromising structural weather barriers.
Adopting thin-profile Vacuum Insulated Glass units delivers U-factors as low as 0.60 W/m²K (0.10 BTU/h·ft²·°F), matching solid insulated wall values. Combined with low-emissivity (Low-E) coatings and warm-edge spacer technology, our storefront profiles achieve net-zero energy building compatibility.
Transitioning to recycled 6063-T6 aluminum billets processed via hydro-electric energy reduces embodied carbon. Surface treatments utilize chrome-free passivation layers and VOC-free powder coatings, complying with REACH, RoHS, and LEED v4 Environmental Product Declarations (EPD).
To streamline architectural specifications, Zenit provides native Revit BIM models and parametric 2D/3D CAD files for all custom door profile systems. Architects and structural engineers can seamlessly run FEA (Finite Element Analysis) for wind loads and thermal simulations prior to extrusion tooling.
How Chengdu Zenit leverages vertical integration, massive component networks, and automated precision manufacturing to lower total cost of ownership for overseas partners.
Operating a 25,000m² manufacturing hub, Zenit manages aluminum profile extrusion, thermal break assembly, CNC precision notch milling, corner crimping, and insulated glass unit (IGU) fabrication under one roof. Vertical integration minimizes vendor handoff delays and eliminates intermediate markups.
Supported by more than 600 qualified supply chain vendors, we secure high-grade raw materials—from primary 6063 aluminum ingots to Technoform polyamide strips, Siegenia/KSS hardware, and Kuraray SGP interlayers—guaranteeing stable production cycles even during global supply chain volatility.
With an experienced R&D team of 42 engineers releasing 50+ new architectural profile designs annually, we rapidly prototype custom extrusion dies within 14 days, offering tailored storefront depth profiles, custom anodizing (up to 25 microns), and specialized architectural powder coatings.
