REHABILITATION

HANGAR DOOR REHABILITATION vs.
NEW INSTALLATIONS

Over the years we have noticed that on many occasions there has been no reason for existing hangar doors to be replaced with a new system. If the structural steel in the door is in good condition there should be no reason for replacement. Rehabilitation means a cost savings over replacement. As an additional benefit, you retain full use of the hangar bay by the maintenance crews while all the door work is being done. Below are several items that can be replaced to extend the life of your existing hangar door system.

New drive units installed with either a cable system or pick up bracket configuration

  • This system can easily be installed in non-motor operated doors
  • Instead of 2 or 3 people opening and closing the doors, or a tug, this is now a single person operation.
  • This is also an energy saver, which will cut down monthly bills and keep production at its highest level.

TAIL DOOR REHABILITATION & NEW INSTALLATION
Specializing in fascia and soft fit modification for maximizing hangar bay use. (Ask about our Northrop Grumman project.)

Aperture door modification consisting of:

  • Structural steel re-work
  • Closure door motor installation
  • Pnuematic seals around tail of aircraft
    • A must have for facilities throughout the U.S. in cold and damp climates looking to maximize production in their maintenance bays

WEATHERSEAL REPLACEMENT - Energy Saver!

WINDOW INSTALLATION - For more light within hangar bay

BOTTOM RAIL REHABILITATION
Often we see the bottom rail system lifting because of freeze and thaw effects from weather and severe pitting and deterioration of the steel rails from water sitting in one particular area. This can affect door operation. We have done several jobs where this has occurred and completed these jobs even while the hangar bay was of use to the customer. Our company can design a new drain configuration with an in concrete heat system, for proper drainage in pocket and opening area. This will keep doors working properly in freezing conditions.
