Before and After Diamond Doors

Retrofit Aviation Hangar Door

Considering a door upgrade for your hangar? Diamond bifold hangar doors are easily installed on existing buildings. Here’s how we make it simple.

Arrives Assembled for Easy Install

Our doors arrive onsite fully assembled, pre-wired, and finish painted for easy installation. Unlike competitor designs that ship in pieces, our doors ship in an “A” frame, making retrofit hangar door installation a breeze.

Maximize Overhead Space

A bifold hangar door helps you maximize the potential of your hangar by using your entire clear opening. The self-supporting header option allows you to mount your door above the roofline, giving you the maximum overhead space your hangar will allow.

The Support Your Door Needs

Does your hangar need a little extra structural support? The self-supporting header option supports the weight of your bifold door without causing undue strain on your hangar. It’s a cost effective solution that doesn’t sacrifice quality.

Can I operate a bifold door in high winds?

We do not recommend operating a bifold door during high winds. While the door is designed to withstand high winds in the closed and locked position, having it open during extreme weather conditions could result in severe damage to your door, building, or property.

How difficult is it to install a Diamond door?

Installing a Diamond door is relatively simple. Doors can be installed with standard tools and equipment (including a fork lift or similar equipment). We provide a complete installation manual with every door to guide the installation process, and our service team is available to answer any questions that may arise.

What door sizes does Diamond Doors offer?

While common door sizes vary depending on industry, Diamond Doors manufactures doors of almost any size. We’ve built everything from general aviation hangar doors, quonset doors, farm shop doors, and a hangar door for the Royal Aviation Museum of Western Canada that measures over 100 feet wide.

What happens if I need to use my door when the power is out?

We have included an emergency manual opener on each door motor to ensure the door can be open and closed when there is a power failure. Each motor is equipped with a hex shaft, which can be used with a socket wrench or cordless drill to manually turn the motor.

How well does a bifold door seal against harsh weather?

A Diamond bifold door provides an excellent seal against harsh weather, especially compared to other door styles like overhead and sliding doors. We include several door components in our design that work together to provide a secure seal.

Can I install a bifold door on an existing building?

Yes, Diamond bifold doors are easily installed on an existing building. If the building is not capable of supporting the door, you can add the required structural supports to your existing building or ask about our self supporting header option.

Where can I find an installation crew for my Diamond door?

Diamond Doors has installation crews across North America. If you are looking to hire someone to install the doors you sell, or to service doors for your existing customers, give our office a call and we would be happy provide you with the names of trusted door installers.

Custom Bifold Hangar Doors

Every Diamond Door is custom made. While we have standard sizes that we manufacture, each door is engineered to your building specifically, taking into account building specifications, features, and options needed. With competitive pricing, we can offer you a high quality door at a price you can afford. You can easily get an estimate with our quote builder or contact our office to speak with a sales associate.

Jared Jestice’s Aircraft Hangar Door

Jared Jestice lives in Fulton County, Arkansas, surrounded by the foothills of the Ozark Mountains. He and his family own and operate Jestice Contracting, a construction company specializing in concrete and installing steel structures. “That’s on the side,” says Jared with a smile. “Flying airplanes is first.”

As far back as he can remember, Jared’s passion has been flight. His father was a pilot before Jared was born, and Jared’s first memory is of being in an airplane. “And so, at that point, I was already ruined,” he says…
