Engineered for extreme performance, compliance-certified, and custom-manufactured in our Foshan precision extrusion plant.
In modern commercial construction, high-frequency entryways are subjected to immense structural stress. Conventional butt hinges concentrate the door's entire weight onto two or three localized points on the frame, leading to eventual door sag, frame misalignment, and secure latching failures.
A geared continuous hinge solves this fundamental mechanical flaw by distributing the door's weight uniformly along the full height of the frame. Through a system of interlocking gears housed within a continuous extruded aluminum cap, these hinges ensure smooth operation, high security, and exceptional longevity, making them standard for high-traffic environments like schools, hospitals, and transit hubs.
As a leading China manufacturer, LvXing Intelligent Equipment Co., Ltd. combines premium aluminum materials (featuring Fenglu profile technology) with advanced engineering to supply globally certified architectural solutions at factory-direct pricing.
Established in 2015 and based in Foshan City, Guangdong—the global capital of aluminum extrusion—we deliver world-class structural solutions.
We utilize premium Fenglu aluminum, offering a diverse range of profiles for flexible applications. Our extrusion capacity spans 1xxx, 2xxx, 3xxx, 5xxx, 6xxx, and 7xxx alloys.
Operating production lines ranging from 800T to 20,000T, we can manufacture complex shapes with section widths up to 1.2 meters and total profiles reaching 28 meters.
Our operations are fully certified to GB/T19001-2016 and ISO9001:2015 quality system protocols. We prioritize meticulous material traceablity and precision testing.
Integrating military-grade material standards, state-of-the-art aluminum extrusion, and years of engineering expertise.
Aerospace Certification: We hold the "Special Aluminium Materials for Aerospace" Certificate, confirming our ability to meet stringent mechanical criteria.
Our continuous hinges rely on the same alloy standards required by aerospace programs. This guarantees excellent fatigue resistance under high frequency operations.
Advanced Profiles: Made using Fenglu aluminum profiles. Custom shapes up to 1.2 meters wide or 28 meters long.
By partnering with premium extrusion clusters, we gain access to 800T to 20,000T hydraulic presses capable of processing highly complex profiles with tight dimensional tolerances.
R&D Team: 15 years of experience translating client concepts into verified physical products.
Our engineers understand localized construction requirements, wind-load ratings, and architectural hardware specifications, allowing us to prevent common field issues before production begins.
For international hardware distributors, commercial building contractors, and OEM specifiers, sourcing geared continuous hinges directly from a China manufacturer provides a balance of price and performance. By anchoring production in Foshan—a major global base for aluminum metallurgy—we deliver cost efficiencies through raw material sourcing, automated processing, and proximity to major deep-water ports.
Over 85% of high-traffic door service calls are due to structural door sag caused by standard butt hinges. Upgrading to a geared continuous hinge distributes the load over the full frame height, preventing maintenance issues and door drop.
Our manufacturing processes utilize automated milling, drilling, and multi-stage anodizing. This guarantees that every hinge meets strict dimensional requirements and maintains protective finishes, even in coastal or industrial environments.

For major construction projects, hardware must comply with strict national and international building codes. Our geared continuous hinges are designed to meet global standards:
Quality assurance begins with raw material verification. We analyze chemical compositions and mechanical properties of all received aluminum billets. Extrusions are monitored to ensure uniform profile thickness and straightness.
For geared hinges, teeth engagement profiles must be precise. Our CNC machines cut gear patterns within a 0.05mm tolerance, preventing loose movement or binding. Final assembly includes manual inspections to confirm smooth rotational operation before packaging.
