Explore our premium architectural catalog of continuous geared hinge configurations. Fully compliant with international fire and mechanical load certifications.
Continuous geared aluminium hinges represent a quantum leap in commercial entrance engineering. Unlike traditional butt hinges that concentrate door weight onto two or three localized stress points, continuous geared hinges distribute gravity, kinetic impact, and shear forces evenly along the full height of the frame. This prevents door sag, minimizes maintenance costs, and dramatically extends the lifecycle of heavy glass, wood, and metal doors in high-frequency commercial entries.

We have a team of technicians with 15 years of invaluable experience. Our deep understanding of customer requirements allows us to identify potential structural issues and offer practical design insights, turning complex architectural ideas into tangible products that meet specific structural load needs.
For modern commercial developments, access controls, and escape route assemblies, hinges must carry official CE Certification. Lvxing’s heavy-duty continuous geared hinges are tested to meet the performance criteria established under European Harmonized Standards.
Our heavy-duty aluminum hinges undergo cyclic load testing and corrosion mapping to ensure compatibility with European and North American building codes. Under the scope of EN 1935, heavy-duty building hardware must demonstrate load retention and zero structural deformation under intensive cycle loads. When specifying hinges for emergency egress, escape routes, or heavy structural glass frames, utilizing certified hardware guarantees that the doorset meets life safety codes.
Furthermore, our surface treatment technologies yield hard coat anodizing layers (often exceeding 20 microns) that comfortably satisfy Grade 5 (Very High Resistance) of the EN 1670 corrosion standard. This makes them ideal for pool environments, coastal projects, and chemical processing facilities.

Get Engineering ConsultationContinuous geared aluminium hinges are installed in areas where standard pivot or butt hinges often experience premature wear or failure.
School doors experience high physical impact and occasional abuse. Continuous hinges prevent door sag, protect children's fingers by covering the gap between the door and the frame, and lower maintenance costs in busy school corridors.
Cleanroom environments and hospital entrances need to operate smoothly for heavy gurney traffic. Geared hinges are clean, operate without oil, and can be optioned with integrated hospital tips to simplify sterilization and dust management.
Retail storefronts, airports, and public transport hubs require door hardware that can withstand millions of cycles. Our continuous geared hinges distribute loads evenly, making them suitable for heavy glass storefront entrances subject to high wind loads.
Architectural hardware is adapting to modern energy performance standards and smart building technologies. Three main design trends are currently shaping heavy-duty continuous geared hinge manufacturing:
1. Seamless Smart Access Control Integration: Commercial doors are increasingly utilizing smart access systems, electrified panics, and digital locksets. Modern continuous hinges feature concealed electrical power transfers (EPT) and pass-through wiring, protecting low-voltage power lines within the gear assembly.
2. Structural Sustainability and Circular Design: High-performance aluminum profiles are highly recyclable. Our production utilizes low-carbon aluminum billets extruded using clean-energy systems, helping architects secure credits under environmental rating systems like LEED and BREEAM.
3. Enhanced Heavy-Duty Load Profiles: Modern architectural designs favor taller, wider, and heavier entry doors, which require high-strength hardware. We develop advanced profile designs and use durable thrust bearings to ensure reliable performance under high structural loads.
Answers to common questions from commercial architects, structural designers, and global procurement agents.
Continuous geared hinges run the full height of the door, distributing weight along the entire frame. This design eliminates localized pulling forces, preventing door sag and frame deformation even with heavy, high-traffic commercial doors.
Fenglu aluminum is recognized for high-grade alloy formulations and dimensional consistency. Using this raw material ensures our structural extrusions have high tensile strength and yield performance, allowing our hinges to meet demanding cycle and load ratings.
Yes. We can customize the extrusion profiles to include electric power transfers (EPT) or concealed flat cables. This design allows low-voltage wiring to pass from the frame into the door leaf securely, protecting it from physical wear and tampering.
