Explore our core product portfolio of continuous geared hinges, engineered for structural resilience, aesthetic concealment, and certified performance.
Established in 2015 and strategically situated in Foshan City, Guangdong—the core of global metallurgical manufacturing—LvXing Intelligent Equipment Co., Ltd. has established itself as an industry-leading manufacturer of high-performance architectural and industrial gear hinges. Driven by an elite R&D team with extensive experience, we translate challenging engineering blueprints and architectural requirements into high-load, reliable hardware systems.
Our operation utilizes premium Fenglu Aluminum profiles, enabling us to manufacture continuous geared hinges that endure severe cycles. With our high-end extrusion infrastructure, ranging from 800T to an advanced 20,000T capacity, we process architectural alloys across the 1xxx, 2xxx, 3xxx, 5xxx, 6xxx, and 7xxx series. This allows the production of complex profiles with dimensions reaching 1.2 meters in width and 28 meters in length, tailored for high-specification projects.
Lvxing’s quality control aligns with global standards. Certified under the GB/T19001-2016/ISO9001:2015 standard, we ensure that every batch of concealed geared continuous hinges meets load-bearing, corrosion resistance, and alignment criteria before leaving our facility.
An in-depth analysis of how high-performance continuous hinges solve load-bearing and alignment challenges in high-traffic applications.
Traditional butt and pivot hinges focus weight on concentrated stress points, leading to sag and misalignment over time. In contrast, geared continuous hinges distribute door weight evenly along the entire height of the frame. The meshing gear design inside the hinge cover ensures smooth rotational movement, reducing stress on the door structure and building envelope.
Concealed continuous hinges fit within the clearance between the door leaf and the frame. This design conceals mechanical components, protecting them from vandalism, and eliminates the visual gap. This provides a flush profile and serves as an integrated finger guard, which is essential in educational and commercial environments.
Using premium 6000-series (such as 6063-T6) and 7000-series architectural aluminum alloys ensures tensile strength and resistance to mechanical fatigue. Under constant friction, the internal gears undergo anodizing treatments that prevent metal-to-metal galling, ensuring millions of maintenance-free cycles.
Combining technological superiority with decades of engineering experience to deliver high-quality aluminum profiles.
We have officially obtained the "Special Aluminium Materials for Aerospace" Certificate, confirming our technical capabilities to supply high-stress profiles for demanding applications.
We utilize high-quality Fenglu aluminum profiles. With extrusion lines ranging from 800T to 20,000T, we produce alloys 1xxx, 2xxx, 3xxx, 5xxx, 6xxx, and 7xxx up to 1.2m wide and 28m long.
Our team of technicians has 15 years of industry experience. We assist clients in designing, prototyping, and refining custom continuous hinges to meet complex installation requirements.

Custom-engineered continuous hinges adapted to diverse environmental constraints and regional building regulations.
Designed for public entrances, transit hubs, and retail doors. Continuous geared hinges prevent door sagging caused by high-volume use or wind load stresses.
With CE-certified, clean-profile designs, our hinges minimize micro-particle generation and withstand harsh sanitization solutions in pharmaceutical and medical cleanrooms.
Continuous profiles prevent gaps at the hinge side, acting as a built-in safety guard to prevent fingers from getting pinched in heavy classroom doors.
As smart cities and building automation expand, the demand for integrated access points is growing. Lvxing’s current engineering developments focus on embedding micro-wiring channels directly within the gear assembly. This enables the transfer of power and communication protocols (such as PoE and Ethernet) from frame to door without exposed cabling, supporting smart locking systems, biometric sensors, and automated entryways.
In addition, our sustainability roadmap prioritizes using recycled aluminum alloys processed with renewable green energy, helping builders achieve higher LEED certification scores.
Technical guidance and purchasing information for architects, structural engineers, and wholesale buyers.
Concealed geared continuous hinges distribute load evenly along the full height of the frame, rather than focusing weight on two or three points. This design reduces sagging, wear, and structural stress on the frame. It also provides clean aesthetics and minimizes pinch hazards by eliminating gaps on the hinge side.
Yes. Utilizing Lvxing's high-capacity extrusion lines (up to 20,000T) and 15 years of R&D experience, we can engineer custom continuous profiles with thick-walled sections and robust internal gears. This allows us to handle doors weighing up to 1,000 lbs in heavy-duty or high-security applications.
We typically utilize 6063-T6 aluminum for commercial and architectural projects due to its balance of strength, corrosion resistance, and finish quality. For high-stress applications, we also process high-strength 7xxx series and other specialized alloys depending on project specifications.
Our manufacturing facilities are certified under the GB/T19001-2016/ISO9001:2015 standard. Additionally, we manufacture products to meet CE certification requirements, verifying they conform to international standards for safety, performance, and durability.
Pricing is based on several key factors: alloy grade selection, profile thickness, surface treatment class (e.g., hard-coat anodizing), custom length requirements, and order volume. Please contact our technical team to receive a detailed quote tailored to your project requirements.
