When the fire occurs, the fireproof expansion sealing strips automatically expand, sealing the gaps in the door gaps, blocking the air circulation between the two spaces, effectively preventing the smoke from being exposed to the fire in the early stage of the fire, and controlling the fire spread.
Application Fire-proof door, wooden door, community security door, heating furnace, heat sink, building pipe wells etc.
