We aspire to be your trusted business partner and warmly invite you to visit our factory in Foshan to experience our scale and technical prowess firsthand.
Uncompromising metallurgy, state-of-the-art extrusion machinery, and seasoned engineers form the bedrock of our high-quality door & window hinges.
We have obtained the exclusive "Special Aluminium Materials for Aerospace" Certificate, confirming our ability to process and manufacture profiles that withstand high tension and extreme thermal stresses.
We utilize high-quality Fenglu aluminum profiles. With extrusion lines ranging from 800T to 20,000T, we produce alloys 1xxx, 2xxx, 3xxx, 5xxx, 6xxx, and 7xxx up to 1.2m width or 28m length.
Our veteran engineering crew leverages 15 years of technical experience to analyze shear stress, load pathways, and installation kinematics, ensuring your customized window and door requirements are met flawlessly.
Understanding how gear profile geometry and material selection elevate door longevity and reduce maintenance costs.
Unlike traditional butt hinges that concentrate door weight onto two or three pinpoint screws, continuous geared hinges run the full length of the door header and jamb. This aligns the gears to distribute weight evenly, reducing wear on the frame and eliminating door sag.
Utilizing high-tensile 6000-series (such as 6063-T6) aluminum profiles ensures our hinges achieve exceptional yield strengths. These alloys exhibit excellent resistance to local shear cracking and are highly receptive to deep anodization processes.
Our anodization treatment reaches Class I thickness specifications. This chemical bond creates an aluminum oxide layer that protects hinges from coastal salt air, extreme humidity, aggressive cleaning agents, and direct UV radiation.
Architectural and industrial door systems require tailored hinge configurations based on traffic density, security risk, and climate exposure.
School and hospital entrance doors undergo thousands of cycles daily, often facing severe abuse. Standard hinges quickly develop play, causing alignment issues and latch failures. LVXING continuous geared hinges transfer the door's momentum smoothly across the entire frame. This minimizes tension on the fasteners, preventing door drop-off and keeping fire doors perfectly aligned for safe egress.
Retail and logistics centers in coastal regions face high winds and salt fog. By utilizing our T6 aluminum continuous hinges with stainless steel self-lubricating thrust bearings, facility operators avoid oxidation and mechanical seizing. The continuous structure also seals the vertical gap between the door and the frame, improving insulation and thermal efficiency.
For installations where physical security is critical, security doors must resist tampering, prying, and impact. Continuous geared hinges eliminate gaps along the hinge line, preventing intruders from inserting crowbars or tools. When paired with our aerospace-certified aluminum materials, they offer exceptional impact resistance.
Unlocking cost efficiencies and rapid turnarounds by manufacturing at the global center of aluminum processing.
Our manufacturing facility is located in Foshan City, Guangdong Province—the heart of China's premium aluminum industry. This location gives us direct access to high-quality raw materials, advanced mold makers, and specialist surface treatment plants. This cluster effect allows us to offer unmatched benefits to international buyers:
How LVXING is driving innovation in smart buildings, IoT integration, and low-carbon manufacturing.
Integrated Power Transfer: As smart access control, electric locks, and IoT monitoring systems grow in popularity, doors require safe wiring routes. LVXING's future technical roadmap focuses on continuous geared hinges with built-in, concealed multi-wire power transfers. This routes low-voltage cables from the frame to the door without exposing wires to tampering or wear.
Sustainable Green Aluminum: In support of global carbon reduction initiatives, we are expanding our use of recycled aluminum alloys. When processed through our advanced extrusion lines, these materials deliver the same structural strength as virgin aluminum but with a much lower carbon footprint, helping you meet LEED green building certification standards.
Protecting your investment with global certifications, thorough testing protocols, and robust shipping safeguards.
Our hinges undergo rigorous cycle testing to ensure long-term durability. We manufacture to meet CE requirements and follow international quality management guidelines under GB/T19001-2016/ISO9001:2015. Every production run is tested for dimensional tolerance, tensile strength, and anodization depth before packaging.
Continuous geared hinges are long, precise products that are vulnerable to bending if mishandled. We protect our shipments using custom heavy-duty cardboard sleeves, inner foam dividers, and reinforced wooden crates. Our logistics team handles export clearance from Foshan and Shenzhen ports, ensuring smooth customs processing and on-time delivery.
