Welcome to Lvxing: Specialists in Aluminum Solutions for Demanding Applications
Established in 2015 and located in Foshan City, Guangdong, LvXing Intelligent Equipment Co., Ltd. boasts a skilled R&D team with extensive experience in the engineering, design, and manufacturing of architectural components. We leverage exceptional technical expertise to effectively transform customers' ideas into reality, consistently meeting their precise requirements.
We utilize premium Fenglu aluminum, offering a diverse range of profiles for flexible architectural and mechanical applications. Our advanced extrusion lines, ranging from 800T to 20,000T, accommodate high-performance alloys including 1xxx, 2xxx, 3xxx, 5xxx, 6xxx, and 7xxx series. This massive machinery enables us to produce complex shaped products with section dimensions up to 1.2 meters in width and 28 meters in length. These products are recognized worldwide for their structural precision and meticulous post-processing, finding broad application in aerospace, military, medical, and high-load industrial sectors.
Our commitment to manufacturing excellence is evident throughout our entire production process, including rigorous quality control checks, thorough packaging configurations, and efficient global shipping procedures. This dedication has earned Lvxing recognition as a national excellent and honest enterprise, along with quality system certification in accordance with GB/T19001-2016 / ISO9001:2015 standards. We aspire to be your trusted business partner and warmly invite you to visit our factory in Foshan to inspect our capabilities first-hand.
Uncompromising quality backed by certified materials and 15 years of technical expertise.
We have obtained the prestigious “Special Aluminium Materials for Aerospace” Certificate, ensuring our processes satisfy the highest structural safety standards.
We utilize premium Fenglu aluminum profiles. With extrusion lines from 800T to 20,000T, we process alloys 1xxx through 7xxx, manufacturing complex profiles up to 1.2m wide and 28m long.
Our engineering team features technicians with 15 years of invaluable experience. We identify potential site installation issues early, custom-engineering hinges to match precise architectural constraints.
An Industrial Whitepaper on Metallurgy, Physics of Load Distribution, and Specification Guidelines
Unlike traditional butt hinges or pivot assemblies, which concentrate the door's total dead weight onto two or three localized screws, a continuous geared hinge distributes load uniformly along the entire height of the frame. This eliminates lateral stress, prevents door sag, and dramatically reduces wear on the door closer mechanism.
The gear teeth run vertically along the length of the hinge, meshing together perfectly under high pressure. They are held in alignment by a full-length gear cap. This design creates a smooth rotation axis, reducing the force required to open exceptionally heavy security or industrial doors.
The selection of the base material defines the tensile yield strength and fatigue resistance of the geared hinge. At LvXing, we utilize premium Fenglu aluminum, focusing primarily on 6060, 6063, and 7000-series alloys:
To resist harsh environments, our aluminum geared hinges undergo architectural anodizing processes (Class I, 18-micron thickness). This treatment prevents atmospheric oxidation, resists scratching, and is available in architectural bronze, black, and clear satin finishes to match standard storefront mullions.
How the Foshan industrial cluster enables cost optimization, compliance, and custom hardware engineering at scale.
Foshan is the global capital for aluminum extrusion and hardware fabrication. This proximity allows LvXing to source high-grade raw billets, perform in-house extrusion on presses ranging up to 20,000T, execute precision CNC milling, and conduct anodizing treatments within a tight radius. The result is minimized internal transit costs, strict carbon footprint controls, and unprecedented manufacturing lead times for large-scale custom hardware orders.
Our 15-year experienced design team handles complex custom drilling patterns, continuous hinges with integrated power transfer cables (electrified hinges), custom leaf cuts for uneven frames, and heavy-duty load configurations. Global procurement teams benefit from full-cycle support, starting with detailed CAD drawing sign-offs and ending with structural physical load-testing simulations before shipping.
Continuous geared hinges are ideal for lead-lined cleanroom and radiation doors. They seal the gap between the door and the frame, preventing the escape of dust, contaminants, or radiation.
Schools have high-traffic entrance doors prone to abuse. Geared hinges prevent fingers from getting pinched in the hinge gap (safety-clear design) and resist heavy wind-loads.
Because a continuous geared hinge leaves no gap between the door and frame, it is virtually pry-proof, providing an excellent deterrent against forced entry.
Ensuring compliance with international building regulations and strict factory quality controls.
When purchasing custom hardware from China, compliance with global building codes is paramount. At LvXing, we address these requirements with the following standards:
