Explore our industrial-grade, certified continuous gear hinge models designed to handle extreme cycle operations.
Founded in 2015 and located in the industrial metal-processing hub of Foshan City, Guangdong Province, LvXing Intelligent Equipment Co., Ltd. (also known as LVXING) has set a global standard in advanced aluminum architectural solutions. Over the past decade, we have transitioned from a localized manufacturing firm into a prominent global supplier of customized continuous geared hinges, serving prominent contractors, distributors, and security architects worldwide.
Our operational capabilities are built upon the foundation of premium Fenglu aluminum, renowned globally for its consistent grain structures and mechanical properties. Empowered by heavy-duty extrusion lines ranging from 800T to a massive 20,000T capacity, LVXING possesses the capability to work with diverse alloy classes—spanning the 1xxx, 2xxx, 3xxx, 5xxx, 6xxx, and 7xxx series. This enables us to extrude sophisticated geometries with cross-sectional widths reaching 1.2 meters and linear lengths extending up to 28 meters.
Our commitment to rigorous manufacturing protocols and engineering precision is certified by national standards bodies and quality system credentials, strictly adhering to the GB/T19001-2016 / ISO9001:2015 frameworks. This guarantees that every geared hinge produced is optimized for structural integrity and cycle durability.

How we leverage high-grade aerospace engineering and specialized alloy manufacturing to outclass traditional hardware suppliers.
Aerospace-Grade Standards: We have successfully obtained the prestigious "Special Aluminium Materials for Aerospace" Certificate. This ensures that the metallurgical composition and grain refinement of our raw aluminum exhibit outstanding tensile and yield strength profiles.
Extrusion Scale: Powered by 800T to 20,000T extrusion lines using premium Fenglu aluminum. We process complex profiles in 1xxx, 2xxx, 3xxx, 5xxx, 6xxx, and 7xxx alloys, generating structural sections up to 1.2 meters wide or 28 meters long with exceptional dimensional tolerances.
15+ Years Engineering Expertise: Our senior R&D and tooling technicians average 15 years of field experience in heavy-duty hinges. We review customer architectural blueprints, identify structural failure modes, and provide solutions that translate custom concepts into viable hardware products.
In high-traffic commercial environments—such as airports, educational facilities, healthcare institutions, and logistics terminals—doors undergo thousands of operations daily. Traditional butt hinges distribute the structural load of the door panel to localized hinge knuckles, causing progressive frame sagging, latch misalignment, and wear on the lockset. This structural failure pattern introduces high maintenance costs and security vulnerabilities.
To address this challenge, global architectural buyers are increasingly transitioning to continuous geared hinges. Unlike traditional hinges, continuous geared hinges distribute the weight of the door uniformly along the entire height of the frame. This reduces structural stress on both the door panel and the frame, preventing sag and ensuring smooth long-term operation, even with extremely heavy door profiles.
Standard architectural catalogs often fall short when addressing complex architectural challenges—such as oversized entryway profiles, heavy glazed thermal-barrier storefronts, or lead-lined radiation shielding doors. As a factory supplier, LVXING addresses these challenges by developing tailored structural profiles:
Leveraging our 20,000T extrusion system, we manufacture continuous profiles for heavy commercial assemblies. We support custom heights matching monumental architectural designs, including doors over 10 feet tall, ensuring structural rigidity without multi-piece splicing.
We supply specialized high-strength alloys (such as 7xxx series) for military, aerospace, and high-security cleanrooms. This allows us to optimize wall thicknesses while increasing resistance to high shear stress and physical impacts.
Our solutions support continuous geared hinges prepared for electrified hardware (EPT - Electrical Power Transfer). We route electrical pathways through the gear structure to power locksets, sensors, and panic hardware without exposing wire assemblies to vandalism.
We offer specialized coatings including multi-stage powder coat colors, specialized marine coatings, and anti-microbial clear coats for healthcare environments, preventing bacterial transmission while resisting chemical cleanings.
Exporting structural building products requires strict adherence to international building regulations, material declarations, and supply-chain logistics. LVXING maintains dedicated compliance protocols to facilitate smooth project execution for global clients:
Our hinge profiles undergo verification testing for CE EN1935 regulations. This covers load capacity, friction resistance, deformation, and cycle life, enabling direct import for European structural applications.
Designed in alignment with ANSI A156.26 standards for continuous hinges, ensuring performance compliance. We verify cycle-test ratings to ensure structural stability in educational and public projects.
To prevent scratching during transit, hinges are individually packaged in heavy-gauge protective sleeves and packed in custom export-grade wooden crates, minimizing shipping damage.
The next generation of commercial opening systems: Innovation, Sustainability, and Intelligence.
Developing low-carbon and recycled aluminum extrusion profiles, aligning with LEED and BREEAM green building certifications. Transitioning to zero-VOC waterborne finishing processes for reduced environmental impact.
Developing smart geared hinges featuring integrated cycle-counters and alignment sensors. These hinges collect usage data and alert facility managers when maintenance is required before structural misalignment occurs.
Testing specialized nano-composite inserts for continuous gear teeth. These inserts reduce mechanical friction, eliminating the need for periodic lubrication and achieving maintenance-free life cycle performance.
Answers to common questions from architectural hardware consultants, project estimators, and global distributors.
Continuous geared hinges distribute weight evenly along the entire height of the frame, rather than focusing it on discrete spots. This prevents door sag, reduces stress on frame anchors, and extends the lifespan of both the door and locksets. They also eliminate gap points between the door and frame, enhancing safety, energy efficiency, and security against tampering.
For standard commercial applications, 6063-T6 aluminum offers an optimal balance of structural strength, corrosion resistance, and finish quality. In high-abuse settings, we recommend higher tensile alloys like 6082-T6 or 7075, which we can extrude on our heavy-duty lines to meet demanding structural specifications.
Yes. With extrusion lines ranging from 800T to 20,000T, we can produce profiles matching specific frame heights up to 28 meters. We offer custom powder coatings in any standard RAL color, as well as Class I and Class II clear, dark bronze, and black anodized finishes to meet design requirements.
Our quality control process complies with GB/T19001-2016 and ISO9001:2015 standards. We utilize computerized dimensional testing, digital surface checks, and load cell stress analysis on every batch, ensuring compliance with international project specifications.
Lead times range from 15 to 30 days depending on extrusion complexity, order volume, and finish requirements. For custom tooling, we design, test, and approve profiles within 14 days. We work with leading global shipping lines to arrange efficient container freight from the Port of Guangzhou or Shenzhen.
