Introduction:

Fire-resistant roller shutters, compared to regular roller shutters, have higher requirements for fire resistance and must comply with the national standard GB 14102-2005 and the TF3 fire resistance level requirements. This product is widely used in various industrial, civil, and public buildings that require measurement of backfire surface temperature rise and low wind pressure resistance, such as office buildings, supermarkets, department stores, exhibition halls, underground garages, and entertainment venues, for the fire separation of building sections. According to the provisions of the standard, fire-resistant roller shutters with a fire resistance limit of not less than 3 hours, judged by the backfire surface temperature rise, are classified as first-grade fire-resistant roller shutters.
