Explore our primary line of precision-engineered, high-performance continuous hinges optimized for commercial aluminum frames.
Modern commercial facades demand structural integrity, thermal efficiency, and long-term durability. Traditional butt hinges concentrate the physical load of heavy entrance doors onto isolated pivot points. This concentration causes localized structural fatigue, sagging frames, and misalignments that compromise perimeter security and weatherproofing.
For aluminum profile structures, the introduction of CE Certified Continuous Geared Hinges provides a radical shift in load distribution. Rather than pivoting on individual pins, continuous geared hinges run the entire vertical span of the frame. The weight of the door leaf is distributed evenly along the channel, virtually eliminating shear stress on the aluminum extrusion.
As an industry-leading OEM/ODM manufacturer, Lvxing bridges the gap between raw extrusion capacities and precision mechanical fabrication. Utilizing premium aerospace-grade alloys, our geared hinges undergo exhaustive quality validation to ensure compliance with European standards, rendering them resilient to millions of opening and closing cycles.
Established in 2015 in Foshan City, Guangdong, LvXing Intelligent Equipment Co., Ltd. delivers high-precision aluminum solutions based on heavy industrial capability.
Our state-of-the-art production base leverages premium Fenglu aluminum, offering a diverse range of profiles for flexible applications. Our extrusion lines, ranging from 800T to 20,000T, accommodate alloys in the 1xxx, 2xxx, 3xxx, 5xxx, 6xxx, and 7xxx series, allowing us to produce shaped products with section dimensions up to 1.2 meters in width and 28 meters in length.
These products are recognized for their precision and meticulous processing, finding broad application in aerospace, military, medical, and industrial sectors. Our commitment to excellence is evident throughout the manufacturing process, rigorous quality control, thorough packaging, and efficient shipping procedures, earning us recognition as a national excellent and honest enterprise under GB/T19001-2016 / ISO9001:2015 quality system standards.
Aligning physical durability with smart commercial building infrastructure trends.
By integrating CNC tooling configurations with high-output extrusions, Lvxing ensures gear profiles possess pitch tolerances beneath 0.05mm. This guarantees consistent mesh along the whole length of the hinge, reducing rotational drag and minimizing wear.
We are engineering future-ready hinges with hollow electrical pass-through lines. These pathways enable concealed power transfer from the aluminum frame into the door panel, facilitating hidden wiring for motorized locks, access card systems, and smart sensor integration.
Utilizing hydro-powered smelting inputs from Fenglu profiles, Lvxing continuous hinges meet stringent environmental declarations. This green footprint assists global architects in securing LEED v4 and BREEAM certifications for sustainable building envelopes.

From extreme high-traffic retail storefronts to sterile medical isolation chambers.
In busy North American shopping malls and European transport hubs, doors endure millions of impacts. Continuous geared hinges distribute these dynamic loads across the entire frame channel, minimizing pivot stress. This keeps doors aligned and prevents dragging on floors, reducing maintenance costs.
Modern clinical facilities demand dust-free environments and tight acoustic seals. With a smooth gear mechanism and non-shedding polymer bearings, Lvxing geared hinges operate smoothly without creating metallic dust, making them ideal for ICU vestibules and lab entries.
Heavy industrial generator cabins and soundproof control rooms require structural panel stability. The strength of Lvxing 6063-T6 aluminum profiles handles heavy acoustic doors, providing reliable sealing and sound reduction.
Our factory in Foshan, Guangdong—the heart of China's aluminum fabrication industry—gives us direct access to the entire supply chain. By utilizing raw materials from Fenglu Aluminum and managing every step in-house, we control costs and ensure high quality at every stage.
This concentrated cluster allows Lvxing to source premium billets, execute precision hot extrusion, perform CNC milling, and apply architectural anodizing coatings all within a tight geographical area. For global buyers, this means reduced lead times, consistent material quality, and reliable deliveries, even during global shipping disruptions.
Our heavy industrial capability is anchored by extrusion presses up to 20,000T, allowing us to produce custom long hinges (up to 28m) that meet structural demands for large-scale skyscrapers, high-end infrastructure, and aerospace applications.
Ensuring our hardware passes inspection in any regulatory jurisdiction.
Lvxing's geared hinges are engineered and tested in accordance with EN 1935 requirements. This covers pivot friction, load capacity, dynamic wear tolerances, and safety classifications required for European construction projects.
Designed for fire-rated door assemblies, our hinges help maintain structural integrity under extreme heat. This prevents the door from sagging or buckling, keeping smoke and fire contained within fire barriers.
By minimizing rotational friction, Lvxing continuous hinges help door systems meet opening force limits (such as ADA-specified forces), ensuring easy access in public spaces.
