Explore our premium range of continuous geared aluminum hinge products, certified for durability, precision extrusion, and extreme load capacity.
Traditional butt hinges and pivot hinges concentrate the entire door's weight onto limited anchor points, generating extreme shear stress on both the door frame and the wall structure. Over time, high-traffic commercial installations inevitably suffer from door sag, misalignment, and structural fatigue.
Continuous geared aluminum hinges fundamentally revolutionize load distribution. By running the full height of the door, they distribute weight uniformly, transferring loads to the frame and wall structure. Fabricated from premium architectural-grade aluminum extrusions, these assemblies utilize a gear tooth design with full-length bearings that ensure flawless alignment, low opening forces, and a life expectancy measured in millions of cycles.
A national excellent and honest enterprise leveraging high-precision metallurgy and design capability to turn engineering ideas into reality.
Lvxing has obtained the prestigious "Special Aluminium Materials for Aerospace" Certificate. We conform to tight aerospace-grade tolerances and microstructural requirements, assuring unyielding durability.
Utilizing high-quality Fenglu aluminum, we process 1xxx, 2xxx, 3xxx, 5xxx, 6xxx, and 7xxx alloy formulations. We can manufacture complex geometries with sections up to 1.2m wide and lengths extending to 28m.
Our deep engineering understanding allows us to detect design anomalies, prevent tolerance mismatch, and deliver practical insights. We transform custom architect briefs into commercial-ready profiles.
Established in 2015 and situated in the industrial cluster of Foshan City, Guangdong Province, LvXing Intelligent Equipment Co., Ltd. specializes in advanced aluminum hardware and structural solutions. Our enterprise utilizes premium Fenglu aluminum billets, providing a diverse, stable range of alloys designed for extreme mechanical performance. Our factory operations, certified under the GB/T19001-2016/ISO9001:2015 standard, are managed with meticulous attention to process optimization, quality control, packaging, and logistical efficiency.
Our engineered extrusion capacities—ranging from 800T to 20,000T—make us a critical supply chain partner for aerospace, military defense, medical cleanrooms, and high-frequency commercial entrances worldwide. We collaborate closely with engineers, procurement specialists, and architectural distributors to supply custom and wholesale continuous geared hinges that exceed international regulatory benchmarks.
How we are engineering the next generation of building envelope solutions and smart entrance technologies.
We are actively developing smart hinge systems embedded with ultra-thin piezoelectric cycle counters and strain gauges. These components monitor door alignment, cycle counts, and load fatigue in real-time, feeding diagnostic data directly into centralized Building Management Systems (BMS).
In alignment with global net-zero mandates, Lvxing is transitioning to low-carbon aluminum sourcing. By processing green billets smelted via clean energy grid inputs, we aim to reduce the embedded carbon footprint of our architectural hardware range by 35% over the next three years.
Our engineers are testing advanced fluoropolymer composite bearings that minimize friction between gear teeth. This innovation promises to eliminate maintenance schedules entirely, guaranteeing smooth opening action for up to 3 million cycles without lubricating grease.
Engineered to adapt to distinct high-intensity environments where standard hinges fail.
Schools, airport terminals, shopping plazas, and public transit nodes experience millions of entries annually. Our continuous geared hinges prevent door sagging and alignment failures caused by constant physical force.
In medical and microelectronic cleanrooms, hinges must prevent particulate accumulation and withstand harsh chemical disinfectants. Our anodized aluminum profiles offer non-corrosive, easy-to-clean interfaces.
Automated manufacturing environments rely on heavy protective guards and access panels. Utilizing heavy-duty 6000-series alloys, our continuous hinges carry significant loads without micro-deformation over time.
Certified under specialized aerospace alloy guidelines, our high-strength hinges (such as 7xxx series) deliver outstanding strength-to-weight ratios, crucial for transportable shelters and radar installations.
Foshan City in Guangdong is the world's most dense aluminum extrusion and hardware manufacturing ecosystem. This proximity allows LvXing to minimize logistics, tooling development, and manufacturing lead times.
By partnering directly with Fenglu Aluminum, one of China's premier raw material producers, we secure a stable supply of high-purity aluminum billets. This integration shields our international wholesale buyers from material shortages and price volatility.
Our in-house capabilities extend from die design and high-pressure extrusion (up to 20,000T) to automated CNC milling, chemical anodization, and rigorous mechanical performance testing.
Ensuring our heavy-duty continuous geared aluminum hinges comply with international building and safety standards.
Our continuous geared aluminum hinges carry full CE Certification, validating compliance with European health, safety, and environmental protection standards.
Designed to support low opening and closing resistance, our gear configurations help doors conform to the strict operational force standards mandated by the Americans with Disabilities Act (ADA).
Our quality system is verified under the GB/T19001-2016/ISO9001:2015 framework. We enforce systematic monitoring at every manufacturing checkpoint, from billet verification to packaging.
Comprehensive answers to complex questions regarding aluminum alloys, mechanical properties, and installation configurations.
For architectural geared continuous hinges, we predominantly use 6000-series aluminum alloys, specifically 6063-T6. 6063-T6 offers an optimal balance of structural strength, corrosion resistance, and excellent surface finish during extrusion and anodization. For extreme stress aerospace or military enclosures, we process high-strength 7000-series alloys (like 7075), which provide exceptional yield and tensile strengths to handle dynamic forces.
Butt hinges concentrate a door's load on two or three localized points. This structural load applies concentrated lateral stress to the top hinge, causing structural frame deformation and door sag. A continuous geared hinge spans the full height of the door, distributing weight uniformly along the frame. The dual geared sections roll against one another using polymer bearings, neutralizing lateral stress and ensuring long-term alignment.
Extrusion line tonnage indicates press capacity. Lower tonnage presses (like 800T) are suited for thin, detailed architectural hardware profiles. Higher tonnage presses (ranging up to 20,000T) allow the manufacturing of large-format structural aluminum elements—up to 1.2m wide and 28m long. This dynamic range allows us to produce both delicate hinge components and large-scale industrial frames in the same facility.
We provide Class I (minimum 0.7 mil / 18 microns thickness) and Class II (minimum 0.4 mil / 10 microns thickness) clear and color-anodized finishes. Class I anodizing is recommended for coastal settings, medical cleanrooms, and exterior entryways subject to high wind and moisture exposure. It resists corrosion, color degradation, and scratching over decades of service.
Yes. We specialize in custom-extruded continuous geared hinges. We cut profiles to match exact door frame specifications, up to 10 feet (3.05 meters) or taller for heavy industrial access gates. Pre-drilled screw holes are precision CNC-machined to ensure quick installation.
Every batch undergoes comprehensive testing, including: dimensional inspection using high-resolution optical projectors, alloy chemistry confirmation via spectrometry, tensile/yield strength testing, hardness verification (Barcol/Webster), film thickness analysis for anodization, and dynamic load testing on pneumatic test stands to verify smooth operation.
