Seattle is home to pioneering global tech hubs, massive maritime ports, and advanced aerospace assembly lines. These high-performance settings demand architectural solutions that can withstand both extreme high-traffic usage and severe coastal environment stress. Continuous geared hinges represent the gold standard in commercial door control, offering unparalleled load distribution across the entire frame assembly.
Unlike standard butt hinges that focus force on small, concentrated points (which leads to door sagging, alignment failure, and structural frame fatigue), a continuous geared hinge runs the full length of the door. This design distributes structural loads evenly, preventing the mechanical failure of heavy commercial glass, hollow metal, and thick timber doors commonly specified in Puget Sound area development projects.
Select from our premium, architectural-grade lineup engineered specifically for high-capacity applications across Washington State.
At our core, we deploy the industry's most advanced aluminum processing systems. Using high-purity Fenglu aluminum, our state-of-the-art facility features extrusion presses ranging from 800T to 20,000T. This enables us to extrude highly complex profiles, reaching continuous sizes of up to 1.2 meters in width and 28 meters in length.
For architectural project managers in Seattle, this capacity ensures that extra-tall entrances, grand atrium doors, and heavy security gates can be equipped with single-piece continuous hinges, avoiding weak joints or multi-piece configurations.
Our metallurgy team manipulates chemical compositions to match specific environment demands. Whether you require structural resilience in seismic designs or corrosion defense near Seattle maritime terminals, we engineer the optimal temper:
| Alloy Series | Primary Alloying Elements | Mechanical Properties & Seattle Applications |
|---|---|---|
| 6063-T6 | Silicon & Magnesium | High aesthetic finish quality, excellent corrosion resistance. Optimal for Seattle commercial storefronts. |
| 6061-T6 | Magnesium & Silicon | High structural strength, widely utilized in heavy-duty commercial entryways and high-traffic public institutions. |
| 7075-T6 | Zinc | Ultra-high strength-to-weight ratio. Engineered for specialized high-load, security-sensitive aerospace and defense gates. |
| 5000 Series | Magnesium | Maximum resistance to salt spray. Tailored for marine docks, industrial shipyards, and waterfront facilities in Seattle. |

Our expert technical consultants anticipate installation issues, design custom clearances, and provide detailed blueprints to realize your custom designs.
Standardized and custom configurations designed for commercial retrofitting and new construction developments across the Seattle metropolitan area.
Architects and engineers drafting plans for buildings along Seattle's coastline face unique environmental issues. The combination of persistent rain, marine salt spray, and extreme humidity accelerates galvanic corrosion and rust in inferior steel hinges.
Lvxing continuous geared hinges solve this with architectural-grade anodized aluminum. Because the geared leaves mate along their entire length and are enclosed in a protective cap, internal components stay clean and dry. This design prevents wind-driven moisture from corroding the gears, ensuring long-term performance.
Furthermore, local safety regulations like the Seattle Building Code (SBC) dictate egress operations during emergencies. Our geared hinges maintain precise frame alignment, which keeps fire doors operational even if building foundations settle or experience seismic vibrations.
Standard butt hinges isolate all door weight onto 2 or 3 small points, causing screws to tear loose and frames to warp. The pinless continuous geared design features two geared profiles held together by a gear cap, distributing the weight along the entire height of the frame.
This distribution reduces wear on closing devices and locks, ensuring smooth operation. Our continuous hinges prevent door sag, keeping latching points aligned and reducing expensive maintenance calls for high-traffic facilities.

Our gear movement reduces operating resistance, helping heavy exterior doors stay within the maximum opening force requirements of the Americans with Disabilities Act (ADA).
Our continuous hinges can be specified with fire pins to meet UL 10C positive pressure testing requirements, making them suitable for 90-minute wood and 3-hour metal fire doors.
Offered in Clear, Dark Bronze, and Anodized Black. These architectural coatings provide excellent abrasion and corrosion resistance in marine environments.
