Roller Shutter doors are versatile, heavy duty and easily repaired if damaged. The Roller Shutter curtain is made up of individual metal interlocking Slats attached to a Drum. A number of Slats can be replaced if need be as a result of impact or other damage, rather than having to replace the entire Door if it was a standard Roller Door. Heavier duty, a Roller Shutter door can withstand heavier winds, knocks and general wear and tear. Well suited too high traffic areas, heavy usage and both Industrial and Commercial situations.
