The steel fire door only needs to be pushed open by hand, and then it will be closed quietly and automatically, without the noise of knocking like opening the door inside and outside, and then create a quiet environment. The steel fireproof door will not affect the actions of others due to the opening and closing of the door, and can prevent many people with inconvenient actions in the hospital from being obstructed by various equipment or devices to cause trouble.
