Founded in 2015, Chengdu Zenit Window & Door Co., Ltd. operates a premier 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.
In modern sustainable architecture, the fenestration system serves as the critical barrier between interior microclimates and unpredictable exterior environments. Aluminium Tilt Turn Windows represent the apex of European engineering, offering dual-function operation within a single high-strength frame mechanism. Turn the handle 90 degrees, and the sash swings inward like a conventional casement for maximal airflow and easy exterior cleaning; turn it 180 degrees, and the top of the sash tilts inward, creating a secure top ventilation funnel that dissipates interior heat while preventing rain ingress and unauthorized entry.
Utilizing high-density 6063-T5 and T6 architectural aluminum extrusions with profile wall thicknesses ranging from 1.4mm to 2.0mm. Our proprietary multi-chamber design offers exceptional torsional rigidity, accommodating massive floor-to-ceiling glass loads with structural deflection performance exceeding structural wind load limits of 5000 Pa.
By integrating 24mm to 34mm technoform Polyamide PA66 reinforced with 25% fiberglass, our profiles eliminate thermal bridging. This thermal break technology effectively decouples exterior cold/heat from the interior frame, achieving system U-values as low as 0.79 W/m²K (0.14 BTU/h·ft²·°F) when combined with triple argon-filled glazing units.
Outfitted with German-engineered hardware (Roto Frank, Siegenia, or custom Zenit OEM fittings), our tilt turn systems feature mushroom-head locking cams engaged around the entire sash perimeter. This perimeter locking delivers unmatched anti-burglary resistance (RC2 / RC3 security grade) and continuous gasket compression.

Different geographic locations and architectural archetypes present unique structural and microclimatic challenges. Zenit provides tailored window profiles designed to fulfill complex structural building codes across global markets.
Designed for harsh northern climates in Western Europe, Canada, and the Northern US. Featuring triple glazing with dual low-E silver coatings, warm-edge composite spacers, and 95% argon gas fill. Combined with our deep 86mm profile thermal break frame, these tilt turn windows preserve radiant heat, reducing HVAC energy demands by up to 45%.
High-rise structures endure massive atmospheric wind pressures and severe structural deflection. Zenit engineering integrates structural corner keys, stainless steel reinforcement sleeves, and pressure-equalized drainage channels. Ideal for commercial towers requiring large spandrels and expansive glass vistas without sacrificing wind resistance.
Engineered specifically for hurricane corridors in Florida, the Caribbean, and coastal Australia. Features heavy-duty SentryGlas® (SGP) laminated glass interlayers with multi-chamber reinforced aluminum frames. Our impact-rated tilt turn windows withstand missile impact tests (ASTM E1996 / Florida Building Code TAS 201/202/203) and salt-spray corrosion.
Navigating foreign building codes requires rigorous compliance verification. Chengdu Zenit eliminates regulatory friction by designing and certifying systems directly aligned with regional building authorities in target export destinations.
Fully compliant with NFRC thermal performance ratings (U-Factor, Solar Heat Gain Coefficient - SHGC, and Visible Transmittance - VT). Tested under AAMA/WDMA/CSA 101/I.S.2/A440 for air infiltration, water resistance, and structural performance across North American climate zones.
Custom extruded and tested to comply with Australian AS2047 standards for window performance and AS1288 glass selection in buildings. Equipped with stainless steel flyscreens, specialized sub-head and sub-sill flashings, and specific bushfire resistance ratings (BAL 29 / BAL 40).
Adhering to CE marking requirements under EN 14351-1. Incorporating REACH-compliant EPDM gaskets, VOC-free powder coating finishes, and micro-ventilation position locks tailored to European residential ventilation regulations.
Operating out of our 25,000-square-meter Chengdu smart factory, Zenit fuses computer-controlled CNC machining with rigorous human craftsmanship. Our digital production tracking system ensures absolute dimensional accuracy across every custom window sash.
Anticipating future architectural demands, Zenit's R&D division (comprising 42 dedicated engineers) is pushing the boundary of intelligent, carbon-neutral window engineering.
Transitioning from standard double glazing to 8mm ultra-thin Vacuum Insulated Glass units. VIG delivers thermal isolation equivalent to solid brick walls (U-values below 0.40 W/m²K) while reducing total window weight by 40%, easing stress on hardware mechanisms.
Seamless integration of hidden electric drive motors coupled with Building Management Systems (BMS). Windows automatically adjust to micro-tilt ventilation based on interior CO2 levels, humidity sensors, or rain detection alerts without compromising home automation security.
Pioneering low-carbon aluminium billet manufacturing utilizing 75%+ post-consumer recycled content melted using hydroelectric powered smelters. Minimizing embodied carbon in commercial envelope construction for LEED Platinum point accumulation.
We streamline the international sourcing process for project developers, general contractors, and building material distributors across North America, Europe, and Oceania.
Every commercial order begins with 2D/3D CAD shop drawings and BIM models generated by our 42-engineer R&D team. We verify wind loads, structural anchors, perimeter flashing, and seal details prior to extrusion manufacturing.
Choose from standard RAL color powder coatings (AAMA 2604/2605 compliant for 15-30 year weatherability), fluorocarbon (PVDF) spray coatings for extreme UV exposure, or custom anodized finishes (silver, bronze, champagne, black).
Windows are protected with anti-scratch protective film, corner edge guards, fully enclosed fumigated plywood crates, and moisture-absorbing silica gel bags. Optimized for FCL container loading to eliminate maritime transit damage.
