Precision-engineered aluminum alloy products tested for air permeability, water tightness, and maximum structural integrity.
Chengdu Zenit Window & Door Co., Ltd. delivers world-class OEM and ODM architectural fenestration solutions backed by robust operational metrics and continuous engineering innovation.
Founded in 2015, Chengdu Zenit Window & Door Co., Ltd. operates a state-of-the-art 25,000-square-meter manufacturing facility dedicated to producing high-performance aluminum net doors, security screen systems, and thermal break fenestrations. 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 directly to residential home builders, architectural contractors, and Tier-1 building material wholesalers.
Quality control is strictly managed by a team of 35 certified inspectors who perform rigorous air permeability testing, water tightness checks, and frame corner mechanical strength evaluations on every batch. Supported by over 600 supply chain partners, Zenit delivers comprehensive customization options including thermal break profiles, custom anodized finishes, and triple-pane soundproof glass integrated with high-tensile stainless steel security mesh. Driven by an active R&D division of 42 design engineers, we successfully released 50 new architectural window and net door systems over the past year.
An authoritative guide to material grades, structural mesh options, and custom engineering capabilities for enterprise buyers.
Extruded using high-precision 6063-T5 / 6063-T6 architectural grade aluminum. Profile wall thicknesses range from 1.4mm for residential applications to 2.0mm–3.0mm for high-rise security and heavy commercial applications, ensuring exceptional flexural strength and wind-load deflection resistance.
Equipped with 304 or 316 marine-grade stainless steel wire mesh (wire diameters 0.7mm to 0.9mm, 11x11 or 14x14 mesh density). Black electro-static powder-coated to deliver knife-shear protection, anti-burglary barrier security, and superior resistance against salt spray and coastal corrosion.
Incorporates high-performance Polyamide (PA66GF25) reinforced thermal break strips. Effectively decouples interior and exterior thermal transfer, drastically reducing U-values to meet stringent international green building envelope energy requirements (NFRC/CE certified).

Engineered specifically to satisfy localized building code requirements across major Western and global procurement regions.
Our net doors and security screens are manufactured to meet Australia’s rigorous AS2047 fenestration standards and AS5039 security screen test requirements, including dynamic impact, knife shear, and gem pull testing.
Tested for solar heat gain coefficient (SHGC) and U-factor ratings via NFRC guidelines. Select hurricane-resistant lines comply with High-Velocity Hurricane Zone (HVHZ) impact standards for coastal usage in Florida and North American territories.
Fully compliant with EU Construction Products Regulation (CPR). Features low-VOC surface treatments, certified acoustic insulation ratings, and REACH-compliant EPDM weather seals.
Inside Chengdu Zenit's 25,000m² facility: High-precision CNC machining, strip threading, systematic quality inspection, and automated assembly line operations.


















Versatile OEM customization engineered to fit diverse geographical climates and building designs.
Combining heavy-duty bi-fold or sliding aluminum net doors with double-glazed patio systems. Provides unobstructed panoramic garden views, ventilation, and maximum security against unauthorized intrusion without visual clutter.
Heavy-traffic push-pull or glass storefront doors integrated with high-durability stainless steel mesh. Ensures insect protection and air circulation during non-business hours or outdoor dining conversions.
Reinforced aluminum frames paired with corrosion-resistant 316 marine-grade mesh. Specifically designed to withstand high salt air exposure, heavy wind loads, and debris impact in coastal regions.
How Chengdu Zenit protects project timelines, quality control standards, and overall total cost of ownership for international clients.
With an ecosystem of over 600 vetted supply chain partners and a $26M export infrastructure, Zenit buffers raw material price volatility, guarantees extrusion alloy purity, and ensures on-time container shipments even during peak demand seasons.
Our 42 R&D engineers produce 3D CAD modeling, structural load simulations, and sample extrusion prototypes within 10 to 15 business days. This allows architectural contractors to verify fit and finish prior to full mass production runs.
Every order undergoes a multi-stage audit by our 35 QC inspectors. From incoming raw aluminum spectral analysis to finished frame corner tensile tests and hardware cycle trials, zero defective units leave our warehouse.
Discover how next-generation smart automation and material sciences are shaping the future of aluminum net door systems.
Integrating ultra-quiet electric motor drives with smart home automation (Tuya, Zigbee, KNX). Users can control retractable fly screens and security net doors via voice commands, smartphone apps, or environmental rain sensors.
Architectural demands favor minimalist visual footprints. Zenit's new micro-frame series reduces visible frame sightlines to under 20mm while maintaining high structural resistance against forced entry and high wind pressures.
Incorporating hydrophobic and anti-dust nano-coatings onto stainless steel and aluminum mesh wires. This prevents dust accumulation, reduces maintenance costs, and improves optical clarity over prolonged outdoor usage.
