Select from our range of structural profiles optimized for maximum cycle life and zero-sag load distribution.
Understanding structural performance limits, cycle testing under load, and architectural intent.
Meeting strict local building codes, fire regulations, and structural loads while ensuring components do not sag over high-cycle lifespans.
Standard architectural hinges fail in specialized high-clearance gates, thick insulated panels, and military-grade protective doors.
Industrial environments require specialized surface treatments, including high-micron anodization, to withstand salt-fog and chemical exposures.
Engineered reliability built on advanced metallurgy and precise extrusion techniques.
We have obtained the “Special Aluminium Materials for Aerospace” Certificate. This structural validation guarantees that our alloys exhibit optimal grain alignment and minimal internal stresses.
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.
We have a team of technicians with 15 years of invaluable experience. Our deep understanding of customer requirements allows us to identify potential issues and offer practical insights, turning customer ideas into tangible products that meet specific needs.

| Aluminum Alloy Grade | Tensile Strength (MPa) | Yield Strength (MPa) | Key Applications | Corrosion Resistance |
|---|---|---|---|---|
| 6063-T6 | ≥ 215 | ≥ 170 | Standard Architectural & High-Traffic Geared Hinges | Excellent (Anodized Class I/II) |
| 6005A-T6 | ≥ 270 | ≥ 225 | Heavy-Duty Industrial Machine Enclosures & Transit Doors | Very Good (Exhibits high fatigue limit) |
| 6082-T6 | ≥ 310 | ≥ 260 | Structural High-Load Frames, Heavy Marine Doors | Excellent under industrial atmospheres |
| 7075-T6 | ≥ 570 | ≥ 500 | Special Aerospace, Defense & Armor Grade Enclosures | Moderate (Requires specific protective coatings) |
How custom geared aluminum hinges solve critical entry challenges across diverse industries.
In hospital corridors and ICU entrances, swing doors experience high traffic. Custom geared continuous aluminum hinges provide smooth, low-effort operation and eliminate finger-pinch hazards, meeting ADA compliance.
Precision industrial cleanrooms require airtight seals. Continuous geared hinges align the door perfectly along the entire frame, which reduces pressure drops, maintains seals, and minimizes airborne particulates.
Municipal schools, prisons, and bank vaults require high forced-entry protection. Continuous geared hinges eliminate the gaps typical of traditional butt hinges, making it difficult for intruders to wedge pry bars in.

A continuous geared hinge runs the full height of the door, distributing weight evenly along the frame. This eliminates concentrated load points that cause door sag, misalignment, and screw pull-out, significantly reducing maintenance costs over the lifetime of the installation.
Our 20,000T extrusion line allows us to manufacture complex aluminum alloy profiles with cross-sectional widths up to 1.2 meters and lengths up to 28 meters. This enables the production of thick, wide continuous geared hinges and industrial frames with high structural density.
Yes. Our customized aluminum hinges comply with EU building standards, specifically EN 1935, which regulates single-axis and continuous building hardware. We supply full documentation to facilitate compliance and imports.
Yes, we provide custom anodizing (Class I and Class II coatings), including clear, dark bronze, black, and gold colors. These coatings provide excellent protection against weathering, abrasions, and chemical exposure.
We recommend 6063-T6 or 6005A-T6 for standard commercial and industrial traffic. For aerospace, defense, or high-stress structural gates, we can produce continuous geared hinges utilizing 6082-T6 or ultra-high-strength 7075-T6.
For custom profiles, tool mold creation and initial sample extrusion take 10 to 14 working days. Mass production begins immediately upon prototype approval and takes 15 to 25 days depending on the volume and surface treatment.
