Established in 2015 and located in Foshan City, Guangdong—the silicon valley of aluminum extrusion in China—LvXing Intelligent Equipment Co., Ltd. has grown to become a premium pioneer in architectural hardware engineering. Our core competencies focus on transforming intricate customer concepts into high-tolerance structural profiles, specializing in heavy-duty commercial door solutions.
We strictly utilize premium Fenglu aluminum, offering a diverse, elite range of custom profiles for high-performance applications. Our extrusion lines range from 800T to 20,000T. This enables us to extrude advanced alloys including the 1xxx, 2xxx, 3xxx, 5xxx, 6xxx, and 7xxx series. We easily accommodate complex profile sections up to 1.2 meters in width and 28 meters in length, meeting the strict demands of military, aerospace, and medical engineering.
By enforcing GB/T19001-2016 and ISO9001:2015 quality control systems across every phase of production, Lvxing guarantees dimensional accuracy and component reliability. We invite global distributors, commercial developers, and hardware specialists to discover the engineering depth behind our products.
The Lx-02 Continuous Geared Hinge is engineered to distribute door weight evenly across the entire frame. This eliminates localized stress points common with traditional butt hinges. The geared design synchronizes leaf movement for consistent, low-friction operation in heavy-use environments.
Extruded from high-tensile 6063-T6 architectural grade aluminum, the Lx-02 offers excellent load bearing capabilities, rust prevention, and corrosion resistance. The T6 temper provides high yield strength to resist structural warping under high wind loads or physical impacts.
Standard finishes include Class I Clear Anodized (MIL-A-8625 Type II) and Dark Bronze. This protective layer measures over 18 microns thick, defending the profile against coastal humidity, urban pollution, industrial cleanings, and heavy wear.
Engineered with polymer bearings that resist temperature shifts, the Lx-02 eliminates metal-on-metal friction. This prevents leaf alignment issues and eliminates the need for manual grease maintenance over decades of operation.
Traditional butt hinges concentrate the load of heavy exterior doors onto three small spots on the frame. This localized tension often causes door sag and frame misalignment. The Lx-02 continuous geared hinge distributes the weight across the entire height of the frame. This profile strengthens the door system and helps mitigate lateral stress on both the door and the wall assembly.
We have obtained the "Special Aluminium Materials for Aerospace" Certificate, confirming our production quality meets strict aviation and high-load engineering standards.
We provide and utilize high-quality Fenglu aluminum profiles. With extrusion lines ranging from 800T to 20,000T, we can produce alloys 1xxx, 2xxx, 3xxx, 5xxx, 6xxx, and 7xxx. We can manufacture fully shaped products with section dimensions up to 1.2 meters in width or 28 meters in length.
We have a team of technicians with 15 years of invaluable experience. Our deep understanding of customer requirements allows us to identify potential issues and offer practical insights, turning customer ideas into tangible products that meet specific needs.
Standard architectural openings are transitioning from manual security barriers into integrated, digital, and energy-conscious system checkpoints. The engineering path for the Lx-02 series focuses on compatibility with modern smart building envelopes.
Modifying gear tooth geometry to extend tested performance to 3 million cycles, meeting high-security correctional facility standards.
Developing micro-sensors within the cap cavity to monitor door usage, speed variations, and alignment shifts for predictive maintenance.
Introducing specialized 7000-series alloys with advanced multi-layer anodization for marine and highly corrosive environments.
Standard commercial hinges often fail prematurely under heavy traffic, physical impact, or wind pressure. The Lx-02 geared hinge is designed to solve performance issues across several demanding sectors.
Cleanroom corridors and ICU entry doors require smooth, quiet, and reliable operation. The Lx-02's continuous structure prevents air infiltration and dust accumulation, while its self-lubricating bearings support quiet, cleanroom-compliant performance.
School entry doors face high daily use and occasional abuse. The Lx-02's continuous geared design eliminates leverage points to deter tampering, and it prevents pinched fingers by sealing the gap on the hinge side of the door.
Shopping mall entrances, corporate headquarters, and glass storefront doors require durable structural support. The Lx-02 supports doors weighing up to 1,000 lbs (450 kg), maintaining proper door alignment to reduce load on automatic door operators.
Our Foshan plant operates with high-degree vertical integration. This ensures complete control over raw billet chemistry, precision extrusion geometry, final anodization, and automated packaging. Our supply chain is structured to maintain consistent, resilient output despite fluctuating global raw material markets.
Lvxing utilizes automated material handling and computerized aging furnaces. This ensures each batch of 6000 and 7000 series alloys reaches a uniform hardness profile, minimizing internal stresses that could cause warping during milling. Our in-house machining facility features multi-axis CNC centers that mill hinge leaf templates to tolerances within microns.
By keeping raw materials, extrusion, CNC milling, surface finishing, and quality control on a single campus, we bypass third-party bottlenecks. This enables us to offer shorter lead times for custom anodized orders and consistent product delivery for large commercial projects.
Lvxing supports international procurement requirements by offering customized product packaging, clear compliance documentation, and optimized shipping logistics.
We supply standard lengths of 83", 95", and 120", and we can pre-drill custom hole patterns to match specific door templates. This helps speed up installation for field technicians.
Every geared hinge is wrapped in protective film and packed in heavy-duty cardboard tubes or crates. This prevents surface scratches or bending during shipping and port handling.
We offer standard FOB, CIF, and DDP terms, along with full custom clearance documentation, certificate of origin paperwork, and alloy test certificates for bulk orders.
Commercial hardware must meet clear safety and building code requirements. The Lx-02 continuous geared hinge is engineered to comply with key global standards, helping to ensure smooth project approval and long-term building safety.
Lvxing maintains quality control through rigorous testing protocols for every batch of Lx-02 hinges:
