Hart manufacture a range of fire resistant shutters, rated from 30 minutes up to 240 minutes fire resistance, specifically manufactured to customer dimensions and specification. The preparation of the supporting structure of the fire shutters has to be constructed to a strict set of rules as detailed in our data sheet 600 series and in an installation guide.
Our fire resistant shutters can be fitted to brickwork, and blockwork with concrete lintels in the case of 4 hour doors. 2 hour resisting doors can be fitted to insulated and fire protected steel when the steel is fully encapsulated and 1 hour and less fire shutters can be fitted to timber or metal stud partitioning provided it is one hour fire boarded and adequate supporting frame is provided within the structure specifically for the door.
The fire shutters are automatically operated in fire by simple fusible link or battery supported control systems with warning devices providing optional increasing levels of control and sophistication. All materials can be powder coated in any RAL colour to suit the individual counter type and automatic activation in a fire situation can be via fusible link or fire alarm activated. Optional ATEX compliance and SR1-SR3 is available.
