Interstate Manufacturing Associates is proud to offer our specialty line of hinges for both indoor and outdoor application. Our proprietary hinge, known as the Boss Hinge, is a heavy duty hinge that is ideal for estate gates, aluminium doors, and much more. We offer a variety of Boss Hinge styles and models for even the most demanding of applications.

Why do you need a Boss Hinge? 

Heavy-duty specialty hinges are often used in situations where standard hinges cannot meet the specific requirements due to the weight, size, or function of the door, gate, or other objects they are meant to support.

Our Boss Hinge is an Ideal Heavy-Duty Hinge

The following scenarios are prime examples or scenarios in which you might need a heavy-duty specialty hinge, like our custom Boss Hinge:

  • Large or heavy doors: Heavy-duty hinges are often used for large and heavy doors, such as those found in industrial facilities, warehouses, or hangars. These doors can be too much for standard hinges to handle over time.
  • Security gates: Specialty hinges are used in security gates and doors, which need to withstand tampering, impacts, or forced entry attempts. They provide additional strength and durability.
  • Outdoor or harsh environments: In outdoor applications or places with extreme weather conditions, hinges are exposed to moisture, salt, and other corrosive elements. Heavy-duty hinges with corrosion-resistant coatings are essential in these cases.
  • Frequent use: Doors that are constantly opened and closed, such as in commercial or public buildings, require heavy-duty hinges to ensure long-lasting performance and reduced wear and tear.
  • Specialized machinery: Some machinery and equipment require hinges with specific load-bearing capacities and movement characteristics. Specialty hinges are designed to meet these unique needs.
  • Custom architectural features: Architectural elements like large pivot doors or hidden doors may require custom-made heavy-duty hinges to ensure they function properly while maintaining a sleek appearance.
  • Fire doors: Fire doors often require specialty hinges designed to meet fire code regulations and ensure the door closes automatically in case of a fire.
  • Aesthetic considerations: In some cases, heavy-duty hinges are used not just for their strength but also for their appearance. They can be customized to match the aesthetic of the door or gate they are supporting.
  • Unique movement requirements: If a door or gate needs to pivot, fold, or swing in an unusual or non-standard way, specialty hinges may be necessary to accommodate these movements.
  • Safety and regulatory compliance: Some applications, such as elevator doors or hatches on ships, require specialty hinges to ensure they meet safety and regulatory standards.
  • High traffic areas: Hinges in high-traffic areas, such as commercial or public buildings, need to withstand constant use without failing. Heavy-duty hinges are designed for this purpose.

Ultimately, heavy-duty specialty hinges like the Boss hinge are essential in situations where standard hinges would not provide the necessary strength, durability, or functionality for the specific application. That’s why we’ve carefully designed the Boss hinge to meet the unique requirements of various industries and environments, ensuring safety, security, and longevity.

The H20 model is a scaled-up version of the H17, and is well suited for use on steel and aluminum doors or smaller driveway gates.  As with the H17 and H30 models, it is available in either low-carbon steel or aluminum.

H30 Models

The H30 is our most popular model hinge, and sports a more robust but no less attractive design than the smaller models.  The steel models have a larger pin diameter to support larger driveway or estate gates, and is offered in our broadest variety of tab options to mount to your gate.  The aluminum models are made from extruded 6061-T6 aluminum for the greatest strength and durability.

H40 Models

For the heaviest of gates, we offer the H40 series which pivots around a 1″ diameter pin, offering the most support of our standard lines.  Contact us if you would like information regarding tab options beyond what is shown on our site.

Boss Hinge Block Models

Block hinges are available in steel or aluminum in H17, H20, and H30 sizes.  Although simple in appearance by itself, the block hinge style may be just the element you are looking for to complement certain gates.

Bolt-On Hinges

In addition to the hinges above, which are designed to be welded to a metal gate, we also offer hinges that can be bolted to your gate.  This way, the quality of the Boss Hinge can be put to use on gates of nearly any material.
