Quality Cable Lift System
At Diamond Doors, we believe that lift cables are the stronger, more reliable choice. Our high-quality cables have superior longevity, don’t overlap, and don’t require frequent tensioning. We believe in our design and back our quality product with comprehensive 10-year cable warranty.
A Safe & Reliable Shop Door
Diamond Doors has multiple safeguards to prevent the door from coming down, including the electric brake and 10x cable safety factor. Cable failure is extremely unlikely and typical cable replacement is due to damage from equipment.
Before & After Diamond Doors
Retrofit Quonset & Shop Doors
If you are looking to upgrade from overhead sectional or sliding doors, Diamond agricultural bifold doors are easily installed on existing agricultural buildings like machine shops, sheds, or quonsets.
Easily Install Yourself
If you have the time you can hang the door yourself to save on install costs. Our doors ship in an “A” frame, fully assembled, pre-wired, and finish painted for your convenience. We also offer installation through a network of dealers and service professionals for busy seasons or when installing yourself isn’t ideal.
Maximize Overhead Space
Installed to the outside, bifold doors do not take up valuable headroom inside your building. With our self-supporting header option the door can even extend past the roofline, giving you the maximum amount of overhead space that your building will allow. This is a popular option for arch rib quonset retrofits.
Convenient Design
With greaseless hinges and less moving parts than other door designs, you won’t be spending time fixing this piece of equipment. Diamond doors are high quality, convenient, and long lasting – our first bifold is still in operation today. Add the auto-lock and remote opener so you can enter and exit with ease.
Agricultural Door Features and Options
Diamond shop and barn doors are made specifically to your building, taking into account your building needs, structural support concerns, wind load ratings (hurricane/tornado resistant doors), and headroom desired.
Our agricultural bifold doors are equipped with many industry leading standard features. Since each door is made to project you can add optional upgrades that suit what you’re looking for.
Explore our interactive door tour to learn more about our features and options.
Electrical Auto-Latch / Auto-Lock
The auto-lock is the easy, reliable locking option for your door. Using this system allows for a complete remote access door, as the lock engages automatically when the door closes and releases when the door is opened.
Non-overlapping Cable Driveline
In contrast to competitor systems, our cables never overlap. Unlike a cable drum, our design has a continuous diameter. The cables wrap onto the driveline itself, instead of overlapping onto a drum. The result? Superior longevity, reduced cable wear, consistent opening speed, and no frequent tensioning.
Reduced Heat Loss
Your door is closed in the winter more than it’s open, so a strong seal and quality insulation are important. The insulation panels are fastened to the exterior of the steel frame, creating a full thermal break. Our insulation package includes a closed cell neoprene foam around the perimeter of the door sealing the door to the building.
Wind Protection Features
Diamond Doors offers a variety of features and options to protect your bifold door against wind and extreme weather. These options may look different depending on your type of building but you can expect quality and security from your door.

- Manual Lock
- Finish Painted Steel Frame

The Loutchan’s Quonset
The Loutchan’s own a third-generation family grain farm. This farm, originally founded by Ron Loutchan’s grandfather, is nearly 100 years old. With a quonset machine shop built in 1989, the Loutchans found that their biggest difficulty was fitting their large equipment through their old machine shop door.
Having lasted the test of time, quonset buildings (like the Loutchans’) are usually still structurally sound after many years. Despite the building being in relatively good condition, the quonset doors have worn, causing them to become difficult to open, or are too small to…
