What Are Sliding Fire Doors?

Sliding fire doors are a form of fire-rated door designed to prevent the spread of fire and smoke from one area of a building to another. Typically, they are utilised in industrial or commercial settings, such as factories, warehouses, and vast retail spaces, where it is necessary to contain the effects of a fire to a particular area.

Design and Construction

The standard material for sliding fire doors is heavy-gauge steel, which is designed to withstand high temperatures and prevent the spread of fire and pollution. Doors are typically equipped with intumescent strips that expand when exposed to heat, forming a seal that prevents the spread of fumes and flames.

In addition to their fire-resistance, sliding fire doors are designed to be resilient and simple to operate. Typically, they are equipped with ball-bearing rollers and heavy-duty tracks, allowing them to open and close effortlessly and swiftly. They are also designed to be low-maintenance and corrosion-resistant finishes.


Installation of a sliding fire door is a complex procedure that requires meticulous planning and execution. Sliding fire doors must be installed in accordance with local fire safety codes and regulations and equipped with the necessary safety features, such as automatic closing mechanisms and smoke detectors. During the installation procedure, sliding fire doors must also be precisely aligned and balanced to ensure that they function efficiently.

We specialise in the protection of buildings from fire by the insulation of structural members, walls and tanks against direct attack from flames by maintaining load-bearing members and tank-shells below the critical point at which failure or weakening is likely to occur.
