Roller shutter doors have a very low maintenance factor, both in maintenance and repairs.

Roller shutter doors mainly consist of:

• Shaft: (Mild steel barrel, spring loaded for counter balance and easy operation.)
• Guide rails: Mild steel channel 75mm x 25mm x 3 x required length, one on each side. (Hot dipped galvanised, to prevent rusting in coastal areas).
• Slats: (Cold rolled galvanised coil strips formed into the required shape, 80mm x the required length).
• “T” Section: (40mm x 40mm x 3mm x required length to add stability to the curtain of a roller shutter door. This is also hot dipped galvanised to prevent rusting in coastal areas.)
• Canopy: (Cold roller galvanised sheet bent in the sape to cover the shaft and providing the roller shutter doors with a appealing finish).

Options:
Roller shutter doors are very standard in operation and can not be utilised for any other purpose than that for which it has been designed, but it is possible to have a roller shutter door powder coated for more a appealing appearance.

Perforated roller shutter doors are suitable for shop fronts, much the same as grille and Finestra roller shutter doors, where full vision is required to enable passers-by to see shop displays. Finestra roller shutter doors are furthermore suitable for openings or an area that needs to be secured yet needs ventilation like boiler room and undercover parking areas. These roller shutter doors are very much in demand due to their very neat finish and appearance as shop fronts.

Locking:
Perforated shutter doors have very basic and standard means of locking:

• Crank operated roller shutter doors have a crank handle which is lockable.
• Chain operated roller shutter doors are locked by means of a bracket mounted against the guide rail.
• Push-up roller doors use a sliding bolt mechanism on the “T” Section.
• Electrically operated roller shutter doors have no locking mechanism as it is not needed due to the working of the electric motors.
