Fire-rated roller shutters are a fire and heat-insulating solution designed for large openings in buildings, featuring a compact structure with the roller shaft concealed. The shutter surface operates through a transmission device and control system for lifting and lowering. They serve as fire and heat barriers, with a flat and aesthetically pleasing appearance, innovative design, and strong rigidity. Widely used in fire separation zones of industrial and residential buildings, they effectively prevent the spread of fires, safeguard life and property, and are an indispensable fire protection facility in modern architecture.
