Single Skin Fire Shutters

Product Code: FR-1H, FR-2H, and FR-4H

Product Description
Our single skin steel shutters are the most cost effective way to secure an opening and/or compartmentalise against a spreading fire. 
Made from 76mm curved steel, these shutters have been tested by Exova to withstand a fire for 1, 2 or 4 hours depending on your need or budget. 
As with all our motor-driven shutters, fire-rated doors are fitted with safety brakes, coupled with ‘drive ratio control’, to manage controlled descents correctly. Furthermore, we can incorporate one of our interface panels so that the roller shutter closes automatically when the fire alarm is set off.
Shutters are available in sizes to suit your needs and either galvanised or powder coated in a choice of colours. 
Ideal Uses
  • Warehouses
  • Factories
  • Loading bays
  • Other areas where a high level of security is required as well as a high degree of insulation
  • Canteens
  • Restaurants 
Key Features
  • Can be powder coated two different colours, front and back.
  • Can come with window panels if required

In Line motor applications enclosure projection sizes will vary dependent on the overall shutter size.

Note: The enclosure heights are based on standard tube motor operation or In Line external chain drive motor.


Electric: Single phase tubular motor or In Line chain driven motor dependent on curtain weight, with push button control. The fire shutter is usually connected to a Fire Control Panel and integrated with the building alarm system, so that the shutter descends under control of the motor in the event of a fire. 

Manual override facility is available with the UKRS FR range. Optional battery backup will supply at least one operation of the door if electricity supply fails.
