Roller shutter doors are suitable for most applications as the specifications vary widely. There are only two types of roller shutters — manual and electrically operated. The manually operated roller shutters are either push up or chain driven, both of which are fitted with a counter balance spring to assist this operation. The electrically operated roller shutters can be either 230v tube motors or 415v/230v industrial motors, and in both cases are supplied with a standard anti-fall safety brake. The tube motors are suitable for locations where the door is only required to open and close a limited number of times a day, for example on shops and garages. These can be operated by a push button, key switch or remote control. The 415v/230v industrial motors, as the name suggests, are more suited to locations where a more robust product is necessary.
