ROLLER SHUTTERS

Constructed of rust resistant galvanised interlocking slats cold-formed to an accurate profile, interlocked to present a uniform faced curtain. Alternate slats have riveted end locks to prevent lateral movement supplied complete with a reinforced bottom rail.

Steel channel guides are mounted on angled steel securing brackets to give the necessary support.

Constructed from a seamless steel tube fitted with internal helical springs of hard drawn steel wire, wound to a maximum diameter and assembled into the roller without stretching or pre-stressing. Bright steel shafts run in ball races and are strong enough to give full support to the bearings to resist the torque of the springs. The whole roller is greased and sealed before installation and comes complete with the necessary supporting brackets.

The roller shutter is activated to open/close via either a control panel - key switch or remote fob. The door is driven by a tubular motor which is located within the roller itself, this configuration is for a standard 230v single phase operated roller shutter or a direct driven 415v three phase motor which is more commonly used for industrial/commercial operation.

FIRE RATED ROLLER SHUTTERS

Fire roller shutters are supplied by us to ½ hour (30 mins.), 1 hour (60 mins.), 2 hours (120 mins.) and 4 hours (240 mins.) fire resistance, specifically to the customers requirements which will in turn be conditional on building regulations and insurance company requirements.

The sizes range from small openings within commercial installations to very large industrial doors. The recommended method of operation for all sizes is by electric motor, designed specifically for the purpose. These motors provide the necessary safe controlled automatic operation in the event of fire and satisfy health and safety recommendations.

More traditional spring counterbalanced hand operated doors will provide marginally lower cost options, but will have safety and operational considerations.
