Fire-resistant and flame-retardant roller shutters, including the frame, are curtains that meet the requirements for fire resistance, stability, and integrity within a certain period. They consist of curtain slats, drum, motor, guide rail, bracket, protective cover, and control mechanism.

Fire-retardant curtain walls are primarily used for walls that require fire separation, especially for fire-resistant walls and partitions where large openings need to be created for production or use purposes, but fire doors cannot be installed.
