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. This scale allows us to produce continuous geared hinges of extreme length and durability, perfectly aligned for heavy curtain walls and oversized industrial window panes.
We have a team of technicians with 15 years of invaluable experience. Our deep understanding of customer requirements allows us to identify potential design and engineering issues, offering practical insights and turning complex architectural concepts into tangible products that meet specific structural demands.
Combining automated material processing, high-pressure die casting, and real-time Quality Assurance to secure global supply chains.
Located in Foshan, China's core aluminum capital, our manufacturing hub guarantees immediate access to high-purity aluminum billets, advanced mold toolings, and surface treatment facilities. This minimizes transportation lead times and ensures raw material consistency from melt to finished extrusion.
Our workshop houses high-precision CNC multi-axis milling machines capable of processing aluminum profiles up to 28 meters in length. Hinge hole patterns, countersinks, and gear profiles are milled in single-setup operations, ensuring tolerance variations are kept within a strict ±0.05mm margin.
To prevent scuffs and mechanical distortion during international maritime shipping, each continuous geared aluminum hinge is sleeved in custom polyethylene film, boxed in shock-absorbing honeycomb cardboard, and secured within export-grade steel-framed wooden crates.
Innovation in surface finishing, alloy compositions, and structural integration to meet the next generation of architectural standards.
Architectural aluminum hinges face aggressive atmospheric pollutants and coastal salt spray. Our roadmap incorporates automated electrostatic PVDF coating systems and hard anodizing to Class I (minimum 18-micron thickness) requirements. This ensures protection against corrosion, discoloration, and mechanical wear over decades of service.
Leveraging our 20,000T extrusion capacity, we are engineering ultra-high-strength architectural hinges using 7075-T6 aluminum alloys. Typically reserved for aerospace components, these alloys offer tensile yields matching mild steel while maintaining the lightweight, corrosion-free advantages of high-purity aluminum.
We are developing next-generation hinges integrated with low-voltage wiring pathways, enabling seamless power transmission to electronic locks and monitoring systems. These hinges feature integrated thermal-break structures and micro-sensors that report door cycle counts and mechanical alignment drift in smart commercial facades.
From heavy-traffic educational complexes to sterile pharmaceutical cleanrooms, we deliver custom hinges designed to handle high loads and cycle counts.
Heavy-duty, high-load structural glazing demands hardware that prevents door sag. Our continuous geared hinges distribute heavy glass panels' weight evenly across the entire length of the door jamb, reducing stress on structural silicone joints and ensuring smooth long-term operation.
Educational institutes, transit terminals, and retail developments subject doors to millions of open-close cycles. Our continuous geared hinges utilize self-lubricating polymer bearings, reducing friction and wear to eliminate the risk of hinge failure in emergency egress pathways.
Sterile industrial settings require dust-free hardware. Traditional butt hinges create metal-to-metal wear that sheds microscopic particles. Our geared continuous hinges are sealed with specialized protective gear caps and require no external grease, keeping air particulate counts low.

Expert engineering insights and technical answers concerning aluminum window hinge manufacturing, customization, and deployment.
Continuous geared hinges run the full height of the frame, distributing the door's load evenly across the entire frame. This eliminates localized gravity pulling and sag, which commonly cause misalignments in heavy glass facades. They also prevent wind infiltration along the hinge line and eliminate pinch points, increasing overall security and safety.
Fenglu is recognized globally for producing high-purity aluminum profiles with reliable structural consistency. Using Fenglu aluminum ensures that our hinges have uniform thickness, lack micro-voids, and anodize smoothly, preventing structural failures under heavy wind loads or repetitive impact.
A wider range of extrusion presses allows us to match specific profiles with the most efficient production tonnage. Our 20,000T press is designed to handle very wide or thick structural aluminum profiles without sacrificing metal density, whereas smaller presses efficiently handle lightweight, thin-walled designs.
For harsh coastal and marine environments, we recommend a Class I clear or color anodized finish (minimum 18-micron thickness) or high-durability fluorocarbon (PVDF) powder coatings. These treatments pass standard salt spray testing to prevent pitting, chalking, and oxidation caused by airborne salt.
We employ modern digital micrometer tables, automated optical profile projectors, and coordinated measurement machines (CMM) to verify physical profiles. Hinge components undergo strict dimension checks at setup, mid-run, and final assembly, ensuring every piece matches our client specifications within specified limits.
