Fire-rated Rolling Shutters
Fire-rated rolling shutters serve as a physical barrier to protect wall openings from fire. They automatically close in the event of a fire. Gandhi fire-resistant roller shutters are available in stores and offer the same functionality as traditional single-motor shutters—though the key differences lie in the materials used and the types of accessories included.
These fire-resistant roller shutters are designed to remain open under normal conditions, yet automatically close in the event of a fire, preventing the blaze from spreading to adjacent areas. The fusible alloy linkage melts at 74°C, triggering the automatic closure of the fire shutters during a fire.
