Explore our primary commercial-grade architectural continuous hinges designed to eliminate door sag in schools, healthcare facilities, and high-frequency retail entryways across Victoria.
As Melbourne undergoes rapid urban expansion, including major commercial developments in the Central Business District, Docklands, and the Fishermans Bend regeneration zone, structural demands on public buildings have reached unprecedented levels. Entry doors for education hubs, transport interchanges, and clinical facilities are subjected to thousands of open-close cycles daily.
Standard butt hinges isolate the weight of heavy commercial doors to small points, causing structural sag, door latch misalignment, and structural fatigue in aluminum and timber frames. Continuous geared hinges address this design vulnerability by distributing the door's weight uniformly along the full height of the frame. This physical load-sharing dynamic dramatically minimizes wear, extends door lifecycle parameters, and enhances structural security.
For Victoria-based contractors and architects, compliance with the National Construction Code (NCC) and Australian Standards (AS1428.1 - Design for Access and Mobility) is non-negotiable. Continuous geared hinges facilitate compliance by maintaining precise door leaf alignment. This reduces dynamic friction, ensuring that opening resistance remains within the 20 Newton force limit specified for disabled access.
Additionally, Melbourne's varying coastal climate—from high UV radiation to damp, salty sea breezes near Port Phillip Bay—demands hardware with superior atmospheric corrosion resistance. Our architectural continuous geared hinges are finished with structural anodic coatings that act as barrier defense systems against early oxidation and pitting in corrosive C3/C4 maritime zones.

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.
Continuous geared hinges operate via a gear profile where both leaves are kept in mesh by a full-length gear cap. The structural strength of this geometry depends heavily on the aluminum alloy extrusion parameters and temper designation.
Our geared hinges are extruded from high-tensile 6063-T6 aluminum alloy. Tempered to T6 conditions, the metal undergoes artificial aging to increase its yield strength to at least 170 MPa. This ensures that the geared teeth within the hinge do not suffer shear deformation under dynamic loading or heavy wind resistance, common to Melbourne's coastal high-rise buildings.
| Physical Property | 6063-T6 Aluminum (Lvxing Spec) | Standard Commercial Aluminum | Engineering Advantage |
|---|---|---|---|
| Tensile Strength | ≥ 215 MPa | 130 MPa | Resists extreme pulling and wind shear forces |
| Yield Strength | ≥ 170 MPa | 70 MPa | Prevents door sagging over millions of cycles |
| Anodization Quality | Class I (20μm+) | Class II (10μm) | Resistant to coastal Melbourne marine salt sprays |
| Bearing Material | Self-lubricating Polymer | Standard Metal-on-metal | Maintenance-free operation; no black residue build-up |
In regions near Docklands, Geelong, or Frankston, salt-laden sea air accelerates galvanic corrosion. Our continuous geared hinges are anodized in accordance with Class I architectural standards. This electrolytic passivation process creates an ultra-hard aluminum oxide layer that protects the raw alloy. Combined with self-lubricating bearings embedded at precise intervals along the geared segment, our hinge system operates smoothly without needing grease, preventing dust buildup.
Heavy doors in educational institutions like Monash University, University of Melbourne, and local high schools face high-frequency, sometimes rough, daily use. Continuous geared hinges prevent structural sag and finger entrapment by closing off the gap between the door and frame, making them safer for schools.
In Victorian hospitals, sterile swing doors must seal tightly. Continuous geared hinges maintain precise door alignment over hundreds of daily cycles. The closed gear channel prevents dust accumulation, satisfying infection control protocols in hospital settings.
For large-scale warehouses in Dandenong and Campbellfield, heavy security gates and access panels require rugged components. Our 20,000T extrusion line allows us to design and manufacture heavy-duty custom geared hinges that carry loads up to 450 kg without sagging.
