View Product DetailsChengdu Zenit Window & Door Co., Ltd.
A global leader in high-precision aluminum architectural fenestration systems, delivering rigorous engineering and tailored manufacturing for international construction projects.
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.
CE Compliance Standards & Architectural Physics
Unpacking the European Standard EN 14351-1 requirements for external pedestrian doorsets and windows in modern structural envelopes.
CE certification demands rigorous air leakage testing. Our multi-chambered EPDM synthetic rubber gasket system and structural compression seals achieve Class 4 rating (≤ 3 m³/h·m² at 600 Pa test pressure), ensuring complete drafts elimination and maximum HVAC system energy preservation.
Water ingress prevention is dictated by dynamic pressure thresholds. Engineered with tiered drainage channels and concealed weeping systems, Zenit products withstand up to Class E1050 (1050 Pa pressure without leakage), suitable for extreme coastal and hurricane-prone zones.
Extruded from high-grade 6063-T6 aluminum alloys with a wall thickness up to 2.5mm, our door profiles deliver exceptional structural rigidity. Rated up to Class C5/B5, maintaining deflection rates under 1/300th of the span under high wind loads.
Integrating Technoform Polyamide PA66 GF25 thermal breaks and argon-filled warm edge spacer bars, our frame thermal transmittance (Uf) reaches down to 1.1 W/m²K, satisfying Passive House and low-carbon building directives across Europe.
Information Gain Insight: Unlike standard non-thermal aluminum frames that easily conduct ambient warmth or cold, Zenit’s thermal-break doors isolate external temperatures via structural polyamide barriers. This lowers operational building energy requirements by up to 38% annually compared to standard commercial profiles.
Architectural Performance Matrix & Certification Baseline
| Performance Indicator | Test Standard / Standard Code | Zenit Standard Specification | Architectural Impact |
|---|---|---|---|
| Thermal Transmittance (Uw) | EN ISO 10077-2 / NFRC 100 | 0.8 – 1.4 W/m²K (0.14 – 0.25 Btu/h·ft²·°F) | Optimized thermal insulation, zero interior condensation. |
| Acoustic Attenuation (Rw) | EN ISO 717-1 / ASTM E413 | Rw = 38 dB to 48 dB (Double/Triple Glazed) | Substantial noise dampening in dense urban or highway locations. |
| Air Permeability | EN 12207 / ASTM E283 | Class 4 (≤ 0.1 cfm/ft² at 6.24 psf) | Minimal air infiltration, high indoor air quality (IAQ). |
| Water Penetration Resistance | EN 12208 / ASTM E331 | Class E1050 (Static test up to 1050 Pa) | Zero water entry under heavy storms and tropical rainfall. |
| Structural Wind Deflection | EN 12210 / ASTM E330 | Class C5 (Design Load ≥ 5000 Pa) | High safety margin for coastal structures and super tall facades. |
Structural Alloy & Glazing Technologies
Advanced metallurgy combined with precision glazing delivers long structural lifespans and superior structural safety.
6063-T6 Structural Aluminium Alloys
Utilizing high-purity primary aluminum billets extruded at T6 temper condition. Tensile yield strength reaches over 170 MPa with ultimate tensile strength exceeds 205 MPa. Resists corrosion, UV deterioration, and thermal bowing even under continuous extreme direct sunlight exposure.
Advanced Architectural Glazing
Double or triple-pane tempered glass units filled with 95% Argon gas. Coatings include magnetron sputtering double/triple silver Low-E, privacy dynamic smart electrochromic glass, and PVB/SGP laminated hurricane impact glass that retains structural integrity upon severe impact.
European Hardware Systems
Equipped with heavy-duty multi-point locking mechanisms from top European suppliers (Siegenia, GU, HOPPE, Sobinco). System loading capacity supports up to 400kg per sash for oversized ultra-slim sliding glass panels, ensuring smooth operation across 100,000+ cycle durability tests.
State-of-the-Art Production Facility
A look inside Zenit's 25,000 m² automated manufacturing facility, from raw alloy extrusions to final quality control testing.
Localized Architectural Scenarios & Industry Economics
Understanding regional procurement criteria, compliance prerequisites, and Chinese supply chain efficiencies.
North American Residential & Commercial
Requirements in North America focus on strict NFRC thermal metrics and ASTM structural standards. Architectural trends demand large-span slimline sliding doors and hurricane impact bi-folds. Zenit delivers custom jamb depths and target U-factors tailored to North American building codes.
Western European Modern Architecture
European specifications demand strict CE compliance under EN 14351-1, prioritizing minimal profile sightlines and low U-values. Our systems seamlessly integrate into contemporary villas and high-density Passivhaus urban infill projects.
Australia & Oceania Cyclonic Standards
Oceanic regions require compliance with AS2047 and AS1288 certification. Products undergo high wind pressure testing and aggressive salt spray corrosion testing to withstand demanding coastal environments.
China Manufacturing Efficiency Advantage
Operating within Chengdu's advanced industrial ecosystem allows Zenit to leverage integrated supply chains (over 600 local specialized raw material partners). Automated CNC machining lines ensure 0.01mm tolerances, short turnaround times, and competitive volume pricing.
Smart Architectural Openings & IoT Automation
The convergence of minimal architectural design, building automation, and high-performance structural systems.
Motorized Vertical Guillotine Lifts
Automated electric guillotine glass windows serve as seamless dynamic balustrades and open-air dining space enclosures. Controlled via mobile applications, RF remotes, or integrated smart home systems (KNX, Zigbee, Creston).
Automated Environmental Sensors
Integrated wind and rain sensors trigger motorized skylights and sliding doors to automatically seal when adverse weather is detected. Air quality sensors trigger micro-ventilation modes to refresh interior ambient conditions.
Ultra-Slim Hidden Frame Aesthetics
Modern architecture favors expanded glass-to-frame ratios. Zenit’s ultra-slim profiles feature minimal visible frame widths (under 20mm), while hiding track frames inside wall and floor cavities for continuous sightlines.
