Anti Panic Bar For Fire Door
Fire expansion seals are mainly used between the door leaf and door frame, door leaf and door leaf of steel doors and wooden doors. When a fire occurs, the fireproof expansion sealing strip automatically expands to block the gap between the door and the air circulation between the two spaces, effectively preventing the danger of smoke, toxic gas and hot air to the human body in the early stage of the fire and controlling the spread of the fire.
