Manufacturing Bi-fold Hangar Doors | Diamond Doors

Diamond Doors went full time manufacturing in 1998, building custom bi-fold doors for hangars, machine shops, quonsets, storage buildings, architectural projects, and industrial applications.
Dick Suderman, a commercial pilot, started building hangar doors because people had a need. He was determined to build a better door, one engineered for convenience, innovation, and longevity.
Today, Diamond Doors is a thriving company selling directly and through a growing dealer network.
