Booker Airfield is home to a number of REIDsteel structures one of which features a bi-fold door.
The first hangar built in 1999 had top hung sliding doors. One year later, REIDsteel constructed a second hangar, which needed a higher door that was motorised. Given the restriction on height governed by our building built the previous year it was decided that a bi-fold door (also known as a hi-fold) was the answer. This achieved a clear height of 5.3m and a further 0.8m for the depth of the door in its open position.
The third and final hangar was constructed later along the same lines as the original with a top hung sliding doors.
