A roller shutter is a curtain of interlocking steel forming a solid barrier. This construction permits the curtain to roll up or down as it is raised or lowered onto a reel which is mounted onto steel support brackets. A bottom bar fitted to the curtain strengthens the curtain and allows for the fitment of handles and locking devices if needed. The standard slat finish for roller shutter doors galvanized mild steel. These slats can be coated with a wide range of different colors. Roller shutter can be operated by push up or be motorized with electric motors.
