High quality hangar doors ensure that you can focus more on flying and less on maintenance.

High quality hangar doors ensure you can focus more on flying and less on maintenance.

Along with the maximum in height clearance, your hangar door can be outfitted with windows to allow natural light into your hangar. Your hangar door’s cladding material may be matched to the building to create a consistent design aesthetic. Walk through doors create added convenience, and if you have a fabric structure, a free standing header set up adds structural integrity.

Each door is custom built to meet your specific building requirements, includes industry leading standard features and a multitude of safety & security options. We stand behind every bi-fold door we make with a 2 year factory defect warranty, 10 year lift cable warranty and a lifetime hinge bushings warranty.

Custom Built for Pilots, by Pilots

As a commercial pilot and aerial applicator, Dick Suderman began Diamond Doors in the off season with his first custom bi-fold hangar door in the mid 1980’s. That door is still in operation today, meeting the high quality standards that were unavailable at the time. That standard has paved the way for Diamond Doors to become a innovative industry leader with doors engineered and designed to last.
