Steel shutters are used to help prevent unauthorized access and vandalism to premises by adding an extra barrier between “outside” and whatever entrances they may be protecting. When open, the shutters provide an almost unobstructed aperture as the shutter and mechanism store above the doorway and out of the way. Furthermore, the doors are tough and have a long life with little maintenance required.
The curtain is constructed from galvanised continuously interlocked steel laths that are securely held in place by end locks. A number of thicknesses and profiles are available (18swg, 20swg and 22swg as standard) according to individual circumstances such as size, wind loading etc. Bottom rails are generally galvanised and roll-formed into a tee section.
Vertical guides are formed from rolled steel or fabricated dependent on size and are supplied with appropriate angles for fixing to the structure.
Mild steel of appropriate thickness in relation to door thickness is prime painted and supplied with angles for fixing to he structure.
Our barrels are normally made from a seamless steel tube of adequate diameter to counteract deflection and hold in bearings or cups attached to the end plates.
Comes galvanised with non-galvanised parts prime painted as standard. Customers can choose to have a powder coating of almost any colour as an additional extra.
Shutters over smaller openings are typically powered by a 240-volt single phase tubular motor whereas larger shutters are operated using a 400-volt 3 phase geared motor. Adjustable limit switches are incorporated to stop the shutter at the end of each travel.
