Enterprise Engineering Capability & Scale
Chengdu Zenit Window & Door Co., Ltd. is a modern manufacturer of architectural aluminum systems, combining precision metallurgy, thermal break engineering, and automated production pipelines.
Operational Profile & History
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 Assurance & R&D Innovation
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.
Technical Engineering: OEM Customization Standards
For procurement officers and architects, selecting the right aluminum alloy, thermal insulation strip, and structural hardware is critical to meeting building envelope code requirements.
6063-T5 / T6 Aluminum Extrusions
We utilize prime-grade 6063-T5 and 6060-T6 architectural aluminum alloys with wall thicknesses ranging from 2.0mm to 3.5mm for heavy-duty main entry doors. These alloys provide exceptional yield strength, structural rigidity under high wind pressures (up to 5000 Pa), and optimal surface purity for anodizing and powder coating finishes.
Polyamide PA66-GF25 Thermal Breaks
To eliminate heat transfer across metal profiles, our custom doors integrate imported Polyamide PA66 reinforced with 25% glass fiber (PA66-GF25). Combined with optional aerogel isolation inserts, this technology achieves structural U-values as low as 0.85 W/m²K (U-Factor ≤ 0.15), complying with NFRC and Passive House specifications.
Multi-Point Security Locking Hardware
Security is non-negotiable for commercial and luxury residential entry systems. Our OEM configurations feature German-engineered multi-point locking systems (HOPPE, Siegenia, GU) with anti-pry locking bolts, concealed heavy-duty 3D adjustable pivot hinges rated up to 500kg per leaf, and integration capabilities for smart biometric / RFID keyless entry.
Information Gain Insight: Unlike standard off-the-shelf residential doors, OEM aluminum entry doors manufactured by Zenit are engineered with double and triple EPDM weatherstripping seals alongside continuous corner vulcanization, guaranteeing long-term durability, zero water infiltration under hurricane conditions, and superior STC acoustic attenuation above 42 dB.

China Supply Chain Virtues & OEM Procurement Strategy
Leveraging Chengdu's advanced industrial ecosystem, Zenit provides global developers, architectural firms, and distributors with significant lead-time, engineering, and cost advantages.
Vertical Supply Integration
Our ecosystem incorporates over 600 verified material suppliers, spanning ingot smelting, extrusion dies, surface treatments, glass tempering, and hardware manufacturing. This vertical cohesion guarantees uninterrupted raw material supply, standardized alloy purity, and stable bulk pricing even during global market shifts.
Rapid OEM CAD/BIM Prototyping
Backed by our 42-engineer strong R&D department, we offer 48-hour turnarounds for custom structural shop drawings (DWG/STEP/BIM models). Whether modifying thermal break depth, designing oversized pivot profiles, or tailoring flush threshold details, our team translates complex architectural concepts into factory-ready tooling.
Export Logistics & Protection
With 8 years of international export expertise delivering to North America, Western Europe, and Australia, we enforce strict sea-freight packaging protocols: full film wrapping, corner foam protection, steel-framed pallets, and fumigated wooden crates ensuring 100% scratch-free and warp-free arrival at project sites.
Global Building Code Compliance & Certifications
We systematically test and certify our architectural door systems with accredited international laboratories to meet regional structural, water, and thermal building mandates.
North America (NFRC / AAMA / Florida FBC)
Our thermal break doors meet NFRC thermal performance standards and ASTM E283/E330/E331 structural wind and air infiltration metrics. Special hurricane-impact series feature laminated SGP glass engineered for Florida HVHZ (High-Velocity Hurricane Zone) compliance.
Australia & New Zealand (AS2047 / AS1288)
Tested explicitly for the Australian market, our sliding, bifold, and entry systems satisfy AS2047 (Windows and doors in buildings) and AS1288 glass selection guidelines, enduring intense UV exposure, cyclonic wind loads, and severe rain penetration.
Western Europe (CE / EN 14351-1 / Passive House)
Designed to conform to European Union CE directives under EN 14351-1, our ultra-thermal entry series integrates multi-chambered profile designs and warm-edge spacer technology suited for Low-Energy and Passive House residential projects across Europe.
