Fire doors have significant role in ensuring safety of public. Extensively used in hotels, restaurants and various types of commercial structures, these heavy duty doors protect occupants of any specific building during outbreak of fire. Red in color, these pressed cold rolled steel made doors are fitted with intumescent strips that expand during fire outbreak and prevent spreading of flame. Smoke seals of fire doors have significant role in creating positive pressure in a room so that smoke and flame can be exhausted quickly from the fire affected building.
