Roller shutter doors are suitable for locations as various specifications are available that make it adaptable to the environment. In addition, these can be installed on any existing openings. Roller shutters essentially consist of a curtain of interlocking slats, which form a continuous hinge along their entire length. This construction permits the curtain to roll up or down onto a revolving spring-loaded barrel, which is mounted onto steel support brackets. A bottom rail is fitted to the curtain which strengthens it allows it to fix handles and the locking systems. The curtain is also prevented from moving sideways by side channels or guides. The shutter can be raised or lowered either manually or electronically.
