Explore our top-tier continuous geared bifold hinges designed to handle high loads, distribute door weight evenly, and offer lifetime reliability.
Established in 2015 and strategically located in Foshan City, Guangdong (China’s industrial hub for aluminum processing), LvXing Intelligent Equipment Co., Ltd. boasts a highly skilled R&D engineering team with extensive manufacturing experience. We leverage exceptional technical expertise to effectively transform our global clienteles’ blueprint concepts into market-ready architectural realities, consistently meeting and exceeding precise quality thresholds.
Our manufacturing philosophy relies on utilizing premium Fenglu aluminum, offering a diverse and customizable range of profiles for flexible, heavy-duty architectural installations. Our factory footprint includes world-class extrusion production lines ranging in capacity from 800T to 20,000T. This enables us to accommodate premium alloys including 1xxx, 2xxx, 3xxx, 5xxx, 6xxx, and 7xxx series, yielding complex shaped profiles with section dimensions reaching up to 1.2 meters in width and 28 meters in length.
Our structural bifold hinges and custom geared hardware systems find intensive application in high-tier aerospace projects, military equipment assemblies, professional medical sanitization areas, and high-performance commercial construction sectors. Committed to absolute production excellence, we strictly follow ISO protocols verified through quality system certification in accordance with GB/T19001-2016/ISO9001:2015 standards.
Lvxing integrates state-of-the-art aluminum extrusion capabilities with rigorous quality control to deliver superior, high-performance hardware products.
We have proudly obtained the official "Special Aluminium Materials for Aerospace" Certificate. This validates our capabilities to process high-strength structural alloys with extreme fatigue limits and zero tolerance for defect propagation.
We provide and utilize high-quality Fenglu aluminum profiles. With extrusion lines ranging from 800T to 20,000T, we can produce alloys 1xxx, 2xxx, 3xxx, 5xxx, 6xxx, and 7xxx. We can manufacture fully shaped products with section dimensions up to 1.2 meters in width or 28 meters in length.
We have a team of technicians with 15 years of invaluable experience. Our deep understanding of customer requirements allows us to identify potential issues and offer practical insights, turning customer ideas into tangible products that meet specific needs.
Leading the architectural industry through smart design, mechanical efficiency, and high-performance material sciences.
Moving beyond standard 6063-T5 aluminum, our materials division is rolling out tempered 6063-T6 & 6061-T6 variations. This ensures a 30% increase in tensile strength, preventing hinge bending and sagging under extreme panel weights of up to 400kg.
Integrating customized self-lubricating fluoropolymer bearings inside continuous geared mechanisms. This design eliminates metal-on-metal friction, preventing structural wear and yielding bifold operations that exceed 1,000,000 cyclic runs.
Currently researching and developing concealed wired pass-through hinges capable of housing IoT sensors and power lines. This lets door panels securely route digital signals directly through the core structure without weakening the profile.
Implementing aerospace-grade micro-anodizing (25-micron thickness) and architectural-grade fluorocarbon liquid coatings (PVDF) for maritime projects, ensuring over 2,000 hours of continuous ASTM B117 salt spray resistance.
Engineered to integrate seamlessly with global structural standards in heavy-traffic environments and luxury architectural designs.
Engineered for storefront entries, medical corridors, and public hubs. Continuous geared hinges distribute load across the full frame height, preventing door sagging from intensive public operations.
Provides ultra-sleek alignment for multi-panel glass patio doors. Smooth folding actions and narrow profiles optimize sightlines while supporting heavy double-glazed and triple-glazed energy efficient panels.
Specifically anodized for coastal properties exposed to high levels of humidity and wind-blown chlorides. Resists galvanic corrosion, keeping bifold pathways operating smoothly and cleanly.
By leveraging Foshan's extensive raw materials ecosystem, Lvxing operates a lean manufacturing pipeline with short lead times and pricing advantages. Our integrated production facilities utilize smart CNC machineries coupled with 800T to 20,000T heavy extrusion presses. This vertical integration means we handle everything in-house, including:
Our raw material sourcing contracts with premium suppliers like Fenglu Aluminum protect our production lines from metal price fluctuations on the LME (London Metal Exchange), providing stable long-term prices for global wholesale buyers.
