A roller shutter manufacturer explains what a fire-rated roller shutter is.
The fire-rated roller shutter maker produces a door that fits large openings in buildings or commercial sites for fire, heat, and flame resistance. The product meets set technical standards in making and installing. The fire-rated roller shutter is a must-have fire device in modern high-rises. Beyond the normal job of a door, it blocks fire and smoke, slows the spread of fire, and helps rescue and evacuation. Its specific fire role shows in these points:

  1. The curtain material and surface size of a fire-rated roller shutter, and its fire rating, follow the construction budget and settlement standards.
  2. A fire-rated roller shutter must have a controller to move it up, down, and stop. Manual buttons on both sides control the electric shutter’s rise, fall, and stop. After the shutter drops and closes in a fire, it must be able to lift again, then auto-return to closed.
  3. A fire-rated roller shutter builds on the steel shutter by reworking the drive parts and adding fire-rated electrics to get the fire function. A fire-rated motor, run by a fire control box through a speed unit, drives the shaft to open and close the curtain. In a power cut, you can use the manual handle on the fire motor for manual operation.
  4. Electric fire-rated roller shutter — Uses a coupling instead of a sprocket drive. The rail sticky points embed copper or nylon plates. It must suit factories and warehouses that use or store flammable gas or volatile chemicals with high fire or explosion risk.
  5. The electric fire-rated roller shutter works like a fire wall as a horizontal fire compartment. It has 13 parts: curtain plate, seat plate, rail, bracket, shaft, box, control box, door machine, limiter, lintel, manual quick-release, button switch, and safety device. It goes where a fire wall compartment is hard to fit, such as open elevator halls, escalators, and wide department-store floors.
  6. Electric fire-rated roller shutters are gaining favor. Many workshops, shops, and garages fit them. Against manual shutters, the electric type is not just better looking and frees users from unlocking and pushing; it is smart, and more important, it protects life and property with its fire function.
