Profile: McGregor Polytunnels Ltd. specializes in manufacturing buildings and roofed structures. We serve various sectors, mainly the aircraft sector. Our 5.50m wide hangar is a modular hangar which can be built to any length. It is designed for twin blade helicopters and trollied micro-lights. The hangar structure is manufactured from 60.3 mm Z35 hot dip galvanized steel tube. The gable ends are steel and aluminum for a long lasting and high quality finish. The hoop spacing is 1.50m as standard, and it has double side stanchions throughout, which makes it incredibly strong. The door is a heavy duty PVC material with reinforcing steel bars that opens horizontally and clamps securely to the upright. The hangar is clad in a green and white triple layer polythene sheet that is guaranteed against UV degradation.
