Tunnel doors

Special fire-rated, pressure-resistant doors are used in cable tunnels and for cross-passage emergency escape in High Speed Rail, MTR and road tunnel projects. They are specified in single swing, double swing, double egress and sliding configurations and are typically stainless steel construction.

As well as providing protection against fire and smoke, these doors resist the high positive and negative pressure levels created by trains and large vehicles passing at high speed, which in rail tunnels can be as high as +/-15kPa.

For rail and Metro stations we provide complete packages of purpose designed, pressure resistant doors in ventilation shafts, commercial grade doors for platforms, concourses and back-of-house locations, and glass fire doors and screens for entrances and booking halls.
