A Diamond door is a great choice for your farm building.
Here’s a few reasons why.
Get a Larger Door Opening.
Bifold doors provide a clear opening that is wider and taller than what is possible with an overhead door. In addition, because they are mounted to the exterior of the building, the self-supporting header allows you to install the door above your building’s roofline.
Make Your Door Easier to Use.
A Diamond door makes it easier to access your building. Compared to sliding doors that are frequently difficult to move, bifold doors open at the push of a button. Add the remote opener and autolock package to make it even simpler.
Spend Less Time on Door Maintenance.
Designed with fewer moving parts and built from quality materials, you can expect to spend less time on maintenance with a Diamond bifold door. Instead, you can spend more time on what matters to you. Diamond doors are low maintenance and reliable.
Designed for Easy Installation.
We deliver your door directly to your building site – pre-assembled and ready for installation. And if you need someone to handle the install for you, we have a wide network of great door installers across North America.

Outstanding product. Exceptional service. The door fit well, is finished well, and operates flawlessly. They were informative and helpful right from the beginning from ordering to delivery.

Had two Diamond doors installed this past fall. The shop door proved to be very well insulated and sealed perfectly. Also did a self-standing door on the quonset… so much better than the old sliders. Turned out to be a pretty simple install. Very happy!

The wind tore my sliders off of my 60×40 shop. Best thing that ever happened. I replaced them with a diamond door.
Easy DIY install, with great support. Always opens and closes.

What is all included in the price of a Diamond door?
We include all the hardware you need to have your door installed and operational. This ensures you don’t have to spend extra time and budget looking for the right parts. For optional door components, like trims and cladding, we provide a complete list of exactly what you’ll need.
How safe is a Diamond door?
Diamond Doors implements multiple safety features on every door. These features include an electric brake that prevents the door from falling in the event of a power failure, a 10x cable safety factor, and photoeyes that prevent door closure if anything is in the path of the door.
Why choose lift cables over other options?
Our lift cables offer significant advantages over other lifting systems, including other lift cable styles. Our unique driveline eliminates cable tangling, overlapping, and rubbing, which are the most common causes of cable failure.

Bifold Gives New Life to Decades Old Quonset
As a 5th generation farmer, Brodie Durston understands the value of hard work. When his grandfather started the current farm location near Dauphin, Manitoba in 1959, he ran a mixed calf and grain operation. In the early 1960s, he built a quonset that housed his seed cleaning operation. But as the farm continued to grow, it became apparent that more space was required to keep up with the needs of the farm.
Now using the quonset as an unheated shop, Brodie found that the aging sliding doors couldn’t keep up with their needs. They were becoming difficult to move and frequently jammed with snow and debris, causing extra work and frustration. After all, running a mixed calf and grain operation makes efficiency and ease of use a priority in day-to-day operations.
That’s when Brodie started looking at options to upgrade the sliding doors on his quonset. “A friend of mine suggested we look into a Diamond door,” he said. “They have two in use on two separate buildings and had been happy with them.”
The Project
A Diamond door was a good fit for this retrofit project, especially with the addition of the self-supporting header system. This door feature makes it possible to install a bifold door that is sometimes taller or wider than what the quonset would typically allow. In some cases, like with Brodie’s quonset, it can also provide additional structural support to hold the weight of the door.
Brodie also opted to add polycarbonate sheeting to the top half of his bifold door.
Polycarbonate sheeting is a great option to allow plenty of natural light into your building. For Brodie, it makes the quonset a much more pleasant place to work, as it is now brighter and more inviting.
Diamond Doors offers 10mm and 30mm polycarbonate sheeting options. The 30mm polycarbonate, also known as Therma Vu, provides an insulation value similar to that of standard double pane window.
Since Brodie chose to insulate his bifold door, the Therma Vu polycarbonate sheeting was the perfect complement.
While the quonset is currently unheated, the insulation package provides improved temperature control in the shop. Together with his bifold door, it makes the quonset a more comfortable place to work during the frigid Manitoba winters and ensures the building is ready when Brodie chooses to heat the quonset.
The Experience
“The door is great. [We are] very pleased with it and would not hesitate to order another one,” says Brodie. “The full opening height and width is a really nice feature.” He’s happy to recommend a Diamond door to other farmers.
