Film-coated steel sheets offer excellent fire resistance, primarily due to the combination of the film layer and the steel base material. The film layer, typically made of a heat-resistant, flame-retardant material, effectively blocks the spread of flames and heat. Meanwhile, the steel base material itself possesses a degree of fire resistance, maintaining structural stability and slowing the spread of fire in the event of a fire. This combination has led to the widespread use of film-coated steel sheets in buildings and industrial facilities, providing a reliable guarantee for building safety.
