Steel fire rated roller shutter door are fire compartmentation systems constructed primarily from steel components. They are designed to meet the requirements for fire resistance and integrity for a specified period, effectively preventing the spread of fire and safeguarding lives and property.

How it works‌：It consists primarily of core components such as steel slats, guide rails, base plates, rollers, a housing, a roller door operator and a control box.‌‌
It operates by the control system driving the roller door operator, which in turn rotates the rollers, causing the slats to move up and down along the guide rails. In the event of a fire, the system can be automatically activated via interlinked heat and smoke detectors, or manually lowered and closed using a push-button device to form a fire barrier.‌‌

Steel fire-resistant roller shutters are widely used in industrial and commercial buildings where fire compartmentation is required, such as in large openings in firewalls and fire partitions; they are commonly found in hotels, shopping centres, libraries, stations, underground structures, factories and warehouses.
