Roller shutter doors consist of a curtain of interlocking slats that form a continuous hinge along its entire length. This construction allows the curtain (shutter) to roll up or down from a revolving spring loaded shaft barrel mounted onto steel support brackets. A bottom rail or T-Section strengthens the curtain and allows for the fitment of handles and locking devices. The curtain is prevented from moving sideways by channel guides and endlocks. The entire assembly is either bolted or welded to the building structure and the rolling mechanism is enclosed in a canopy hood.
