Where One-Piece Hydraulic Doors Got Their Start

The one-piece hydraulic door got its start in Cottonwood, MN, in 1994. There a welding shop got a request to build a shed door that was sturdier than a bi-fold door, to fit an opening too big to accommodate a roll-up door. The solution was a one-piece hydraulic door called the HydroSwing. The hydraulic door's advantage over bi-fold doors was immediately obvious, and since then the business has grown to manufacture thousands of hydraulic doors for national and international customers alike.
