Our versatile range of single, double, horizontal and vertical sliding leaf constructed steel doors have fire ratings ranging from 1 – 4 hours depending on the type of fire risk involved. They have been designed to meet the highest demands for a pre-painted door for use in a wide variety of applications where fire resistance, security and sound reduction requirements may need to be combined. Fire doors within the corridors can be retained in the open position using electromagnet catches. In the event of a fire or outside working hours, they are automatically released to prevent the spread of fire.
