Fire doors are specialized doors designed to prevent the spread of fire and smoke within buildings. These doors are constructed from fire-resistant materials such as steel or gypsum and are equipped with seals around the edges to inhibit smoke and gases from passing through. Fire doors are strategically installed in fire-rated walls and partitions, serving as barriers to compartmentalize fires and create safe evacuation routes. They typically feature automatic closing mechanisms or magnetic holders that ensure they remain closed during a fire emergency, helping to contain the blaze and protect occupants. Fire doors play a crucial role in building safety, meeting regulatory standards and enhancing overall fire protection measures in residential, commercial, and industrial settings.
