At Ladeau Manufacturing, we fabricate Butt hinges in a vast array of styles, ranging from very simple designs to those with great degrees of complexity. Butt hinges are extremely useful in a wide variety of applications and can be recessed or surface-mounted.

What are Butt Hinges?

Butt hinges are the most common and the most popular type of hinge and could qualify as the simplest hinge option, as well. Typically, Butt hinges will duplicate the appearance of a continuous hinge with the exception of its smaller size that can fit in your hand.

It is common to cut longer piano hinge stock into shorter pieces that result in the Butt hinge variety. More often than not, a Butt hinge will be about 6 inches in length, or shorter. The width and length of Butt hinges are, usually, equal to one another or are of a similar size-scale.

Butt hinges are designed with two rectangular metal plates or leaves that are often joined, via a pin or rod. They can be manufactured with ball bearings instead of a central pin; and the pin can be designed so it is not removable when exposed to the outside, providing enhanced security.

NRPs, or non-removable pin hinges, have an embedded screw located in the barrel that is accessible only if the door is swung open. This added safety feature would prevent a potential intruder from removing the hinge pin and, then, the door itself. For sheds that might house costly tools or equipment, NRP Butt hinges are the perfect solution.

Butt hinges secure two independent, parallel parts in close proximity to each other in this case, the side edge of a door to the adjacent door frame, providing up to 180 degree mobility. When the door is closed, the leaves butt together, with only the pin being exposed.

Ladeau Manufacturing fabricates Butt hinges in Aluminum, Stainless Steel or Steel. These items are available with or without holes or removable pins. Virtually any modification or finish can be achieved to accommodate an endless variety of specifications and applications.

Applications for Butt Hinges

The general purpose of Butt hinges is for use on interior and exterior doors, in addition to items with lids and panels. When made from stainless steel, Butt hinges easily withstand harsh, corrosive environments and have a reputation for sustaining heavy weight requirements.

It becomes obvious that Butt hinges are the go-to hinge for all types of doors and compartments whether residential or commercial. They are used in:

Marine
Industrial
Aircraft
Military, or medical applications
Butt hinges are so relied upon they are, virtually, worth their weight in gold. Lockers, storage compartments, kitchen and bath cabinets, gun cabinets and drop-leaf tables represent only a handful of thousands of items that utilize this invaluable mechanism. Stainless steel Butt hinges can, also, be used on window projects that incorporate casement, round-top or trapezoid windows.

Hinge pins made to MS20253, A-A-55486 and MS27990 specifications, available in a number of materials and finishes. Quickly straightened and cut from stock to any length required. Also available longer than stock length when needed.

Spring loaded hinges can hold a door, panel, etc. in the open or closed position, adding a new level of functionality. Springs of any material, finish and torque are available in order to provide the tension you need in your hinge. We can source standardized springs, and even the most complex springs for your design, due to our long-standing trusted relationship with local partners in spring design and manufacturing. Spring loaded hinges are available in any material and finish. All other aspects of hinge customization, such as hole piercing, swaging, forming, etc. are also available for your spring loaded designs.

A particularly unique custom hinge, solid barrel hinges use compression-loaded pins to enable the easy attachment and removal of panels and related components from many applications. Also called unhinges, these streamlined designs often have a single knuckle running the length of the hinge and are manufactured for their fast release and take apart action, without the need for tools. Further features, such as holes, tabs, etc. are additionally available to manufacture solid barrel hinges to your specific applications.

Hinges, in many ways, make the world go round. Without them, everything from your refrigerator to a cellar door would operate very differently. Next to the wheel, hinges could be considered the 2nd-most-important invention for humanity.

When it comes to the most demanding types of hinges, industrial hinges play a crucial role in a myriad of settings where extreme strength and reliability are a top priority.

What are Industrial Hinges?

Hinges are categorized by a targeted attribute or distinguishing or prominent feature. The term industrial hinge is an umbrella term that refers to any hinge that is used, specifically, for industrial purposes. This would include a wide range of applications such as:

Aerospace industry
Medical
Marine
Agriculture
Military, and more
The physical configuration of industrial hinges vary. Sub-headings of hinges under the umbrella term industrial can include:

As indicated, industrial hinges cater to large industries; and because of this, they are intended as non-consumer products.

To clarify this, hinges you might purchase at a hardware store to hang a door in your home would not qualify as industrial.

On the other hand, hinges that are used to secure body panels to a military vehicle, or strap hinges used to secure tall, heavy doors of a semi-truck would, indeed, meet the requirements of being labeled as industrial.

By far, the most important consideration for any industrial hinge would be its function and the amount of strength required to fully meet that function.

When you see the term industrial, you can be certain the extreme durability of the hinge is of prime importance. In other words, the hinge will easily withstand not only continual use but, even, abuse. At Ladeau Manufacturing, almost 100% of our fabricated hinges fall under the category of industrial.

Applications of Industrial Hinges

As mentioned, industrial hinges meet critical application demands where optimized strength, stability and endurance must be of the highest caliber. A few specific uses of industrial hinges would include the following:
