Tilt-A-Doors
These doors are normally used where head room is at a premium. The design of the door is shown in the diagram below.
Banora Garage Doors actually construct tilt-a-doors to order in their premises. Made from an aluminium welded frame to get the best rust resistance and then sheeted with Colorbond steel, these doors are robust and suitable for the those tight headroom spaces.
Tilt-A-Doors are often used in apartment complex buildings where each unit has its own garage.
