Fire door seals are mainly used for steel and wood doors, wood doors and door frames, between doors and doors. When a fire occurs, the fire door sealing strip will automatically expand to block the crack of the door and cut off the air circulation between the two spaces, effectively preventing early smoke, toxic gas and hot gas from harming the human body and controlling the spread of fire.
