Why Choose a Diamond Door?

As our founder, Dick Suderman, said, “Diamond Doors was a company born because people had a need… bifold doors engineered for quality, convenience, and longevity.” To this day, it is these advantages that make a Diamond door stand out from the rest.

Convenient Door Operation

Your customers no longer need to struggle with troublesome doors to access their building. With features like push button operation, and an optional autolock system, a Diamond door is one built for convenience. Our doors are designed for ease and effortless operation, no matter the conditions.

Maximize the Clear Opening

Unlike an overhead door that takes up space inside your building, or sliding doors that take up yard space, a bifold door maximizes the potential of your shop and yard. Diamond doors are installed to the face of the building, gaining headroom inside the building for maintenance and storage.

Low Maintenance Reliability

We believe that a door shouldn’t be another piece of equipment to look after, but a tool that makes life simpler. With a door designed for easy maintenance, your customers will save time and money. We carefully manufacture each door and include features like greaseless hinges, a reliable locking system, and an onboard electrical diagnostic system.

Quality that Lasts a Lifetime

We are committed to building doors that last a lifetime. Each door is built with careful consideration to the requirements of your building project. In factory, our certified welders use nationally approved welding techniques to guarantee a durable door frame. We source high-quality materials and rigorously test every electrical component.
