The curtain is normally constructed from laths comprising a synthetic material outer skin bonded to a special inner core consisting of high performance insulation materials.
Stainless steel cables connected the laths together and are fastened to the roller at the head.
The bottom rail comprises a standard lath fitted with an extruded PVC bottom seal.
Manufactured from galvanised steel and shaped into a channel profile which is prepared for bolting to the structure by means of continuous fixing angles.
Manufactured from galvanised steel of adequate thickness relative to door size and supplied with steel plates for fixing to the structure.
A combination of galvanised steel and ‘u’ profile and MDF board with a special fire protection cover fastened to the lintel into which the top of the door engages providing an effective seal against the passage of flames and hot gasses.
The barrel comprises a steel tube of suitable diameter and wall thickness to avoid deflection. Steel shafts and discs are inserted at each end and the whole assembly is supported at each end on the end brackets.
Our Fire rated shutters are typically installed with an induction motor, an electromagnetic brake, limit switches and a fusible link. The design provides a reliable system that will close the shutter automatically in the event of a fire situation.
A controlled descent comes as an inbuilt safety feature.
In the event of a power loss, manual operation can be attained. By releasing a pull cord close to the shutter under controlled descent and a hand chain to open again. Every fire shutter is individually operated from a control station, incorporating open/close/stop push buttons positioned adjacent to the shutter guide.
A 24-volt DC auto reset solenoid is available for linking into the fire alarm or BMS.
As standard, the curtain is self-finished light grey with the perimeter intumescent seal in black.
