[0002] Fire-resistant roller shutters are doors made of fire-retardant materials that possess fire resistance, integrity, and heat insulation properties. They are mainly used for firewalls in fire compartments of buildings, underground garages, or shopping mall atriums. In daily life, they are used for pedestrian access. In the event of a fire, fire-resistant roller shutters can prevent the spread of flames and the flow of smoke generated by combustion, while also providing a sealing function.
