A fire shutter has curtain plate, drum, rails, and electric drive. The plate is 1.5 mm cold-rolled steel pressed into overlapping “C” plates, stiff and well sealed. Or a steel “T” series link structure. With heat, smoke, and light alarms and a water curtain, it auto-alarms and sprays in a fire, drops by itself, and closes on a delay so people evacuate. The whole system’s fire performance is clear. Fires happen in many places and hurt people and cause huge loss, worse in factories or crowded public sites.

Many fire products are on the market; the fire shutter is one, with good traits users like. RHidoor introduces its traits:
First, the basic function is fire blocking, from a new material with a high ignition point that is hard to catch fire, so users trust it; sales keep rising.
Second, it insulates, since the material is thick.
Third, it blocks UV well, useful in hot summers.

One-stop after-sales and upkeep.

  1. Fire shutter structure
    A fire shutter is one that, with its frame, meets fire integrity for a set time. It is a fire divider. A vertical shutter normally rolls up in the shaft box above the opening; in a fire it drops to stop the spread through the opening. It is usually set around escalators, at atria to each floor’s corridor, lobbies, rooms, and where a firewall divider is needed.

  2. Fire shutter parts
    It is made of curtain plate, seat plate, rail, bracket, shaft, box, control box, motor, limiter, lintel, manual quick-release, button switch, and safety device. Linked devices: smoke and heat detectors and the fire link system.

  3. Fire rating classes
    By fire limit: ordinary steel (limit >= 2h), composite steel (limit >= 3h), premium (limit >= 4h). Ordinary steel used as a divider needs sprinkler protection.

  4. Control operation
    Auto: after the detector acts, in link mode, a divider shutter drops to bottom; a shutter on an escape path drops to 1.8 m above floor first, then after a heat detector acts, drops to bottom.
    Mechanical: take the chain, pull the shutter-side lock chain down, the shutter descends; pull the other side, it rises.
    Manual: open the box on either side or nearby, press “up” (or triangle) to roll up, “down” (or the other symbol) to descend, middle to stop. Or at the fire control room press the manual key for the module that drives the shutter down; when in place it sends feedback to the room.

  5. Where fire shutters are set
    By process: besides firewalls, where two fire zones have no firewall, set a shutter. Usually at:
    (1) Enclosed escape stairs to corridor; enclosed elevator lobbies to anterooms and anterooms to corridor.
    (2) Check doors of cable, pipe, smoke, trash shafts.
    (3) Doors on firewalls and partition walls dividing fire zones; when a firewall or fire door is hard to fit, use a fire shutter with water curtain protection.

A fire shutter curtain usually has these parts: formed splint, fire decorative cloth, fire cloth, fire blanket, and radiation shield cloth. The filling gives strong fire resistance not just by the outer material but by the filling too. Among common fillings, asbestos is widely used for its high tensile strength, flexibility, chemical and heat resistance, electric insulation, and spinnability as a mineral product.

A premium fire shutter uses steel or inorganic fiber for the curtain, steel for rails, seat plate, splint, lintel, box, with a motor and control box, meeting integrity, insulation, and smoke control. Fire shutters use a two-step descent, sending alarm and action signals to the fire control room; premium shutters have emergency control. When the smoke detector before a fast fire shutter signals, the auto-alarm panel at the fire control desk sounds and lights, logs the time, shows the location, the shutter gets the signal, drops to the set height, and the desk shows it in place.

When a fire shutter replaces a firewall, protect both sides with a water curtain, or use a composite shutter with a rating of at least 3.0h. Shutters in escape paths and anterooms should hold briefly on descent and allow manual control from both sides for safe evacuation; they should support auto, manual, and mechanical control.
