Doors and Extensions for existing Hangars 

You don't even have to spend a fortune. Provided you already have a reasonable Hangar, we can upgrade it for you.

Your company has grown, you need to spread your wings and accommodate larger aircraft. We can help you, at a fraction of the cost of a new hangar.

Many of our customers have come to us in this predicament. They cannot afford the time factor involved, nor the capital expenditure that a new hangar would entail. We have the answers.

New T2 Hangar Door and Extension, Biggin Hill Airport

Inflite Ltd. Hangar Door and Housing, Southend

External Door Housing, Bembridge Airport, Isle of Wight

Britten Norman Aircraft Ltd. wanted to replace the doors on an existing hangar with 30m x 7.7m Crawford Megadoors. This meant putting them on the outside of the hangar with a secondary frame, designed and constructed by REIDsteel. The door housing measures 1.6m x 31m x 8.25m. Steelwork includes galvanised braced frames with columns and rafters, purlins and side rails, and single skin cladding.

Extension and Megadoor for KLM Hangar, Norwich

KLM UK Engineering specialises in the maintenance, repair and overhaul of aircraft, and has its main base at Norwich International Airport. Due to existing and new contracts, as well as the expansion of companies like TNT Airways, KLM were in need of more space. They decided to refurbish a disused hangar, which included a 10m extension of the hangar supplied and erected by REIDsteel. The hangar door was designed and fitted by Crawford Megadoor. An advantage with the extension and the new Megadoor is that the hangar can house the new version of the 737 which is taller than the old model. The electrically operated Megadoor is split in three door leaves, separated by swing-up columns, which enables a full width of 45 m. The two outer door leaves are 9 m high; the centre is 13 m, when fully opened. For full flexibility the door leaves can be individually opened. One row with vision panels allows daylight to illuminate the hangar interior.

The Future - Clear span Hangars 2km long by 100m wide?

One of the most important requirements for a large aircraft hangar is that it should have the widest possible door opening so as to be able to accommodate the biggest aircraft flying or a mixture of many types, large or small, whose comings and goings will not be restricted by widths of door openings, or by having to manoeuvre past other aircraft.

After many years of research we have now designed a hangar whose clear doorway opening can be the entire width of the hangar, whatever its span. For instance, an entrance could be 100 metres or 500 metres, or more without intermediate support columns. This is achieved with a special steel structure and frontal lattice beam.

The design places the highest part of the hangar just where it needs to be - at the front - to accommodate the tail section inside the hangar, without the need for a special tailgate door.

The electrically controlled individually operated doors roll on bottom rails. At the top, vertical rollers operate within precision made guide channels, so that any single door or number of doors can be moved to any part of the ground track and if necessary onto outriggers.

The design allows large areas of workshop and office space at the rear inside the hangar, where the wings do not intrude. Foundations are reduced to a minimum.
