Airport access

Passengers travelling through Heathrow's new T5 building may not know it, but they are likely to have passed over Marshall-Tufflex stainless steel floor boxes delivering access to data and power supply systems vital for the safe and effective running of the airport.

Hundreds of the access units, which are built into the subfloor, have been installed within the terminal building. The lids of the units - some of which are lockable - sit flush with the floor and are designed to comply with Health and Safety legislation for pedestrian traffic. Mostly installed in the departure lounges and connecting internal areas, the units were fabricated in heavy duty stainless steel designed to take higher point load than the standard range of boxes.
