The fireproof curtain is a specialized door for safety and fire prevention. In the event of a fire accident in the theater or at the end of each performance, the fireproof curtain falls down, separating the stage and the audience hall into two fireproof areas, stabilizing the emotions of the audience, preventing chaos caused by fires, and ensuring timely evacuation. The fire curtain is lifted by a weighted drive winch system and can be lowered electrically or freely.
