Chengdu Zenit Window & Door Co., Ltd. combines advanced metallurgical extrusion engineering with Industry 4.0 automation to deliver hurricane-rated storm protection across global B2B supply chains.
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 global trade operations, the company consistently achieves an annual export turnover exceeding $26 million. Our primary export corridors span North America, Australia, and Western Europe, where we directly serve commercial contractors, architectural firms, and premier building material wholesalers.
Quality control is rigidly executed by a specialized team of 35 inspectors who perform exhaustive air permeability testing, high-pressure water tightness verification, and mechanical frame corner strength evaluations. Supported by over 600 qualified supply chain partners, Zenit delivers uncompromised customization options including structural thermal break profiles, architectural anodized finishes, and triple-pane soundproof glazing units.
Driven by an active R&D division of 42 senior fenestration engineers, Zenit engineered and released 50 new architectural window and storm door systems over the past 12 months alone. Our continuous investment in CAD/CAM die design and extrusion physics guarantees that custom OEM partners receive products meeting the strictest structural wind-load requirements (DP70+) and modern energy performance metrics.
Step inside Zenit's smart manufacturing facility. Every aluminum storm door profile undergoes meticulous automated processing, thermal stripping, CNC milling, and structural stress debugging.

Engineered to withstand extreme structural pressure differentials exceeding 4500 Pa (equivalent to Category 5 hurricane winds). Profile corner gussets are crimped using heavy hydraulic corner keys and sealed with two-component polyurethane corner adhesive.
Utilizing multi-layered EPDM weatherstripping gaskets and asymmetric double-glazed acoustic laminated glass, our custom storm doors achieve Sound Transmission Class (STC) ratings up to 45 dB, keeping urban noise outside.
Offered in custom RAL powder coating, authentic wood grain transfers, and hard-anodized architectural finishes designed to endure high UV exposure and harsh coastal salt-spray environments without chalking or fading.
Tailored OEM/ODM architectural solutions fulfilling the strategic, legal, and structural mandates of international developers and distributors.
High-volume custom aluminum storm doors for master-planned suburban communities. Designed for fast jobsite installation with self-storing glass panels, integrated roll-away screen mesh systems, and pre-drilled installation flanges.
Heavy-duty shopfront storm entry systems designed to comply with strict high-velocity hurricane zone (HVHZ) building codes. Equipped with heavy-gauge 6061-T6 structural sub-frames and low-E energy efficient glass matrixes.
Custom retrofitting options that allow historical and modern building owners to add secondary storm protection without disrupting primary entry door architecture. Custom arch shapes, divided lite grilles, and vintage finishes available.
How Zenit leverages China's advanced industrial ecosystem and integrated raw material supply lines to provide cost, capacity, and quality advantages.
From raw aluminum ingot processing and die design to extrusion, thermal break stripping, powder coating, glass tempering, and final assembly—our integrated supply chain minimizes outsourced delays.
Our in-house CNC toolmaker room enables rapid prototype production within 7 to 10 days for custom extrusions. This allows B2B clients to test custom architectural profiles with minimal upfront capital risk.
State-of-the-art 5-axis CNC machining centers perform milling, lock-hole routing, hinge pocketing, and corner keying with sub-millimeter tolerances (±0.1mm), eliminating human assembly errors.
Strategically located in Chengdu's industrial hub with direct multimodal rail and sea export routes, guaranteeing container shipment continuity and standardized export packaging with custom wood crates.
We cross-certify our fenestration engineering against the strict regional building safety and thermal efficiency codes of our target markets.
Engineered in alignment with NFRC (National Fenestration Rating Council) standards for U-factor and Solar Heat Gain Coefficient (SHGC), and tested according to AAMA/WDMA/CSA 101/I.S.2/A440 benchmarks. Florida NOA (Notice of Acceptance) ready profiles available.
Completely compliant with AS2047 and AS1288 requirements. Tested for ultimate limit state (ULS) structural deflection, air infiltration, and water penetration resistance suitable for harsh Outback and coastal environments.
Carries full CE certification under EN 14351-1:2006+A2:2016. Fully audited thermal insulation (EN ISO 10077), safety glass tempering (EN 12150), and air permeability (EN 12207 Class 4) ratings for European Union tenders.
Leading the next generation of intelligent, carbon-neutral, and ultra-insulated storm entry systems through proactive engineering innovation.
