We specialise in designing, constructing and when requested the installation of a wide range of doors and ancillary equipment.  These are applied to road, rail, cable and other various types of tunnels.

The doors and equipment are designed to satisfy all the relevant specifications incorporating fire and pressure – differential pressures – air leakage.  Design considerations also include safety and evacuation requirements.

Doors may be fitted with dampers and be installed into steel bulkheads together with other equipment such as multi-cable, pipe, communications and HVAC transits.
