In high-traffic architectural design and heavy industrial environments, standard butt hinges frequently fail under rotational fatigue and uneven weight loads. Continuous geared hinges solve these failures by transforming localized stress points into a unified distribution system.
A continuous geared hinge consists of two gear-toothed leaves secured by an extruded channel profile. Unlike traditional hinges that focus the entire load of a door on two or three localized pins, a geared hinge distributes the weight along the full height of the frame. This reduces wear on the door closers, frame components, and the structural wall itself. By eliminating traditional pivot points, these hinges resist sagging, withstand extreme shearing forces, and provide exceptional security by eliminating gap access points where pry bars could be inserted.
Lvxing Intelligent Equipment utilizes precise CNC milling alongside state-of-the-art aluminum extrusions to manufacture hinges that meet and exceed industry demands. This translates to lower maintenance costs and structural stability that lasts for millions of operating cycles.
Established in 2015 and based in Foshan City, Guangdong, Lvxing Intelligent Equipment Co., Ltd. has developed into a leading supplier of complex structural aluminum solutions. We use premium Fenglu aluminum to produce engineered profiles that offer flexibility, durability, and strict tolerance control.
Our advanced production facility houses extrusion lines ranging from 800T to 20,000T. This enables Lvxing to manufacture components across a wide range of alloys, including the 1xxx, 2xxx, 3xxx, 5xxx, 6xxx, and 7xxx series. We can process shaped profiles up to 1.2 meters in width and 28 meters in length. This capability supports specialized applications across the aerospace, military, medical, and heavy industrial sectors.
Our focus on engineering standards is reflected in our certifications. We comply with GB/T19001-2016/ISO9001:2015 quality management systems. This ensures every geared hinge matches original drawing specifications from alloy chemistry to surface treatment.
We hold the official "Special Aluminium Materials for Aerospace" Certificate. This guarantees our raw aluminum materials feature the uniform grain structure and tensile strength required for high-stress industrial applications.
Utilizing premium Fenglu profiles and extrusion presses from 800T to 20,000T, we supply alloys across multiple series. We support shaped elements up to 1.2m wide or 28m long, allowing us to manage custom architectural dimensions in-house.
Our engineering department has over 15 years of experience in structural metal fabrication. We identify potential load and wear issues during the design phase, turning custom conceptual designs into functional products.

In municipal buildings, universities, and hospitals, doors undergo continuous operation. Our continuous geared hinges prevent alignment shift. Anodized surfaces resist cleaning solutions and sanitize protocols, making them suitable for sterile environments.
Coastal facilities require robust protection against saltwater corrosion. By utilizing marine-grade aluminum treatments (Class I clear anodizing or custom polyester powder coating), our geared hinges resist pitting and oxidative degradation.
For specialized server cabinets, electrical substations, and cleanroom air showers, doors require tight, continuous seals. The continuous contact profile of our hinges maintains seal compression, preventing particulate infiltration.
Operating within Foshan City, Guangdong—the hub of global aluminum processing—Lvxing benefits from direct access to raw material markets, specialist surface treatment services, and integrated transport networks. This geographic concentration helps insulate our production lines from raw material shortages and logistical bottlenecks.
Our integrated vertical setup covers the full manufacturing sequence: alloy billet cast validation, precision extrusion, thermal hardening treatments, anodizing, and multi-axis CNC machining. Because we manage these steps in-house rather than outsourcing, we maintain consistent quality and shorten lead times.
For international procurement, this means stable pricing, predictable scheduling, and reliable compliance documentation (including certificates of origin and raw material analysis reports).
Modern smart buildings require electrified access control. Our upcoming technical roadmap focuses on integrating internal power transfer cables within the geared core. This design routes power to locksets and sensors while keeping cables hidden and protected from physical tampering.
Through research into aerospace aluminum profiles, we are adapting high-yield 7xxx series alloys for architectural hardware. This produces hinges with high shear resistance and low overall profile weight, making installation easier while maintaining structural strength.
We are developing internal tension systems directly inside the geared hinge barrel. This integration removes the need for separate overhead door closers, creating a cleaner look in modern interior architectural projects.
International building codes demand rigorous compliance certification. Our continuous geared hinges are designed and manufactured to meet major global standards:
Each shipment undergoes cross-section dimensional checks using optical measurement systems, as well as coating thickness validation using digital eddy-current gauges.
We specialize in contract manufacturing and OEM customization. Contact us for direct factory pricing on custom specifications.
