Definition of Fire Doors

Fire doors, also known as fire-resistant doors or safety doors, are simply defined as doors installed at fire-resistant locations, such as fire escape routes, evacuation staircases, vertical shafts, and so on.

Fire doors are typically made from specially treated wood, which is flame-retardant. Then, fire-resistant materials are filled inside the door to achieve fire prevention.

When selecting fire doors, pay attention to the following: angles and seams should be tight and even; plywood should not be sanded through the face veneer and battens; the surface should be smooth and clean or sanded, without saw marks, burrs, or hammer impressions; the coating should be even, flat, and smooth, without drips, bubbles, missed spots, or running.

In summary, a fire door is a door that can insulate heat, resist fire, and ensure safety for a short period of time after a fire occurs.
