Cutter Enterprises contracted for an aircraft hangar door system for new construction of the Fuel Cell and Corrosion hangar located in East Granby Connecticut. The aircraft hangar door system is comprised of a five leaf, one way stacking door system that is clad with an insulated metal panel. The most interesting feature of this system is the use of the clear story panels in the upper portion of the door. WELL BILT supplied the framing to accommodate the glass system and provide a weather tight seal. This door is powered by a single drive unit that WELL BILT manufactures, called the ZEUS drive. The Zeus Steel Wheel design is engineered to be released during power failures. Aircraft hangar doors of this size rely on a powerful and reliable operator to open and close the door, even during icy winter months.
