We utilize premium Fenglu aluminum, offering a diverse range of profiles for flexible applications. Our extrusion lines, ranging from 800T to 20,000T, accommodate alloys 1xxx, 2xxx, 3xxx, 5xxx, 6xxx, and 7xxx, allowing us to produce shaped products with section dimensions up to 1.2 meters in width and 28 meters in length. These products are recognized for their precision and meticulous processing, finding broad application in aerospace, military, medical, and industrial sectors.
Our commitment to excellence is evident throughout the manufacturing process, rigorous quality control, thorough packaging, and efficient shipping procedures. This dedication has earned us 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.
We specialize in structural aluminum components, aligning our engineering processes with global certifications (including CE and ISO). Our focus on material purity and strict tolerance controls guarantees safety-critical components for demanding applications.
Selecting the appropriate door hinge requires balancing architectural demands, frequency of operation, environmental conditions, and mechanical properties. Explore the standard types manufactured at our facility.
Widely regarded as the standard for high-traffic public entrances, continuous geared hinges distribute load across the full height of the frame. The integrated gears assure fluid operation, while the continuous profile prevents door sag and eliminates stress concentrations on the frame.
These traditional hinges are ideal for standard office entries. Our options feature thick-walled extrusion profiles and stainless steel pins, ensuring high lateral stability and wear resistance under standard usage cycles.
Engineered for minimalist projects, these hinges mount inside the door leaf and frame, remaining invisible when the door is closed. They support clean visual lines and modern design languages without compromising load capacity.
Our processes are defined by material control, technical expertise, and advanced manufacturing infrastructure.
We have obtained the "Special Aluminium Materials for Aerospace" Certificate, certifying our alloys for demanding structural integrity and load-bearing performance.
We utilize high-quality Fenglu aluminum profiles. Our extrusion lines range from 800T to 20,000T, enabling us to process alloys 1xxx through 7xxx. We produce shapes with cross-sectional widths up to 1.2 meters or lengths up to 28 meters.
Our technical team brings 15 years of industry experience, allowing us to evaluate design concepts, identify potential functional issues, and refine products to meet custom project requirements.
Foshan is a globally recognized cluster for architectural aluminum. Operating within this region provides distinct operational advantages.
Proximity to primary smelters and major extruders like Fenglu Aluminum allows us to source raw materials with minimal transit delays. This integration helps buffer our clients against sudden global logistics changes and material price fluctuations.
Direct access to specialized tempering and alloy modification facilities enables us to adjust hinge mechanics for unique thermal environments, ranging from extreme cold to humid coastal areas.
Extrusion represents only one part of the process. Our facilities feature multi-axis CNC drilling, counter-boring, and automated milling machines. This high-precision processing ensures that fixing hole alignments conform to close architectural tolerances, minimizing installation time on site.
Architectural hardware must satisfy strict building regulations. Understanding compliance helps secure code approval and ensures long-term safety.
Our continuous geared hinges are designed to meet European Standard EN 1935, which regulates single-axis hinges. They undergo testing for load capacity, friction coefficients, and mechanical wear, ensuring they are suitable for fire-rated and escape-route doors in commercial projects.
Anodized finishes undergo salt spray exposure testing to verify long-term resistance in humid or saline coastal regions. Self-lubricating polymer bearing inserts are integrated within the gear teeth to prevent metal-on-metal wear, maintaining smooth operation over millions of cycles.
The operating force of commercial doors must comply with accessibility guidelines (such as ADA or European counterparts). By distributing weight evenly, our geared hinges reduce starting resistance, helping door closers function within mandated pressure limits.
Continuous geared hinges are ideal for environments with heavy use or potential abuse.
School entrance doors experience heavy traffic and occasional impact. Standard butt hinges can sag under these conditions, leading to alignment issues. Continuous hinges secure the door leaf along the entire frame, reducing maintenance and preventing finger-pinching hazards.
Hospital corridors require heavy-duty doors that open smoothly for gurneys and medical carts. Continuous geared hinges maintain alignment and facilitate easy cleaning, while resisting aggressive chemical sanitizers.
Commercial storefronts require durable architectural components. Anodized geared hinges resist wear and tear from constant foot traffic, helping doors close securely to maintain climate control and security.
For large-scale enclosures and heavy machinery access panels, our 7xxx series and high-tonnage extruded hinges provide the necessary structural strength to prevent sag and ensure alignment under high wind loads.
