Direct factory distribution of CE certified continuous geared door hinges engineered for high-traffic entryways and industrial security portals.
Traditional butt hinges concentrate the entire weight of a heavy door onto isolated points, creating immense mechanical fatigue on the door frame and structural substrates. Under high-frequency usage typical in commercial corridors, school main gates, and healthcare facilities, this stress concentration leads to structural sagging, door misalignment, and security latch failures.
Geared Continuous Hinges resolve this engineering bottleneck by distributing load across the entire height of the door frame. By utilizing a series of interlocking teeth enclosed in a protective cover, geared hinges synchronize the movement of the door and frame leaves. This removes torsional load, eliminates gap-shearing hazards, and increases structural durability under high-impact stresses.
For global engineering projects, CE Certification is the foundational proof of product safety, reliability, and continuous performance. Our hinges are engineered to comply with EN 1935 performance standards, guaranteeing safety in public areas, corrosion resistance in harsh environments, and flame-resistance for commercial applications.
LVXING, SPECIALIZES IN ALUMINUM SOLUTIONS.
Why architectural specification agencies and B2B industrial procurement heads trust Lvxing's manufacturing infrastructure.
We have obtained the "Special Aluminium Materials for Aerospace" Certificate, confirming our raw materials meet military and defense aerospace specifications.
High-quality Fenglu aluminum profiles. With extrusion lines ranging from 800T to 20,000T, we can produce alloys 1xxx to 7xxx, with section dimensions up to 1.2m width or 28m length.
A team of technicians with 15 years of experience. Our deep understanding of customer requirements allows us to identify potential issues and turn concepts into customized products.
How Foshan’s supply chain infrastructure empowers global continuous geared hinge sourcing.
Our facility is located in Foshan, China’s industrial capital for aluminum processing. Partnering directly with premium suppliers like Fenglu Aluminum allows us to source raw structural billets without intermediary logistics costs, passing these savings directly to our clients.
Unlike standard workshops, we possess heavy extrusion lines up to 20,000T. This enables us to extrude highly resilient alloys (such as 6000 and 7000 series architectural aluminum) with optimal grain alignment, ensuring our continuous hinges withstand extreme shear stress.
Our in-house 15-year engineering team creates custom structural dies within 10 to 14 working days. This rapid design-to-sample cycle reduces lead times for bespoke construction projects that require non-standard geared profiles.

| Durability Rating (EN 1935 Equivalent) | Grade 1 / Class 8 (1.5M+ Cycles) | Class 4 (200,000 Cycles) | Class 6 (500,000 Cycles) |
| Gap Security & Anti-Pinch | Full seal (No visible gaps, prevents pinching) | Open gap (Vulnerable to tampering/pinching) | Large pivot gap (Vulnerable to tampering) |
| Material Formulation | Heavy-Duty Extruded T6 6063 Aluminum | Stamped Low-Carbon Steel or Brass | Cast Iron or Stainless Steel |
Modern commercial architecture focuses heavily on public safety, structural longevity, and energy efficiency. Geared continuous hinges are playing a key role in satisfying these demanding building codes globally:
For institutional buyers, sourcing custom-configured hardware involves managing several risks. At Lvxing, we address these challenges through:
Expert technical answers to assist developers, engineers, and purchasing officers with geared continuous hinges.
CE certification guarantees compliance with European safety, health, and environmental standards. For architectural geared hinges, this indicates the product has passed physical load tests, corrosion resistance assessments, and cyclic fatigue evaluations (equivalent to EN 1935). This ensures safe use on escape routes and fire-rated doors.
Fenglu aluminum is renowned for its high mechanical strength, purity, and grain consistency. By using Fenglu profiles, Lvxing ensures the structural leaves of our continuous hinges have the tensile strength and microstructural density required to resist deflection under constant B2B heavy-load usage.
Yes. Our factory offers custom CNC machining for custom lengths, hole patterns, electrical power transfers, and heavy-duty frame configurations. Our 15-year engineering team can quickly turn architectural CAD drawings into production-ready profiles.
Unlike standard butt hinges that concentrate load at small points, a continuous geared hinge distributes the weight across the entire height of the frame. This removes lateral stress from the top hinge zone, preventing sagging, binding, and structural misalignment over millions of cycles.
We primarily use 6000-series alloys, particularly 6063-T6. This alloy offers an excellent balance of tensile strength, corrosion resistance, and finish quality, making it ideal for anodizing and architectural applications.
Standard continuous geared hinge orders are processed within 20 to 30 days. For custom OEM profiles requiring new extrusion dies, the process takes approximately 10 to 14 days for die design and sampling, followed by 25 days for bulk manufacturing.
