Fire doors are a necessary part of any commercial building, whether it be a business, a school, a hospital or nursing home, or a warehouse. There are a variety of sizes in doors available, according to the type of door and what gage it is rated at. These doors are designed with one main function in mind: to prevent the spread of flames and smoke throughout a facility, thus allowing the inhabitants of that building time to escape. The doors are often rated with a length of time and level of heat it can withstand. For example, a door may be rated to withstand a high level of heat for up to four hours.

They may be closed manually or with a motorized mechanism. Fire doors are usually hollow metal doors, with polystyrene filler that has been rated for fire safety. The doors are developed to close and seal off an area, lessening the spread of fire. Often, warehouses and cafeterias will have doors that are made up of perforated slats. These slats are made of galvanized steel, stainless steel, or a clear anodized aluminum. There are various gages the doors may be rated at, according to the type of door that is needed.

Hollow metal doors, such as is seen in schools or hospitals, can even have windows in them. The windows are in internal doors, usually with wire-mesh glass such as Georgian wired mesh. They may also contain liquid sodium silicate, ceramic glass, or Borosilicate glass. These windows are also subject to product certification for ultimate fire safety.
