A fire door is a specially designed door that helps prevent the spread of fire and smoke between different areas of a building. Made from materials that can withstand high temperatures, these doors are essential for maintaining safety during a fire emergency. They are often equipped with self-closing mechanisms to ensure they remain shut when not in use. Fire doors are typically installed in areas such as stairwells, hallways, and between different rooms to create fire-resistant barriers. Proper installation and maintenance are crucial, as damaged or improperly fitted fire doors may not function effectively, compromising the safety of occupants in the event of a fire.
