Metal fire doors are notable for their heavy duty design, vibrant red color and tough construction. Steel core- based design of these fire doors suppresses fire and smoke for a specific duration so that the occupants of a building can get enough time to evacuate. Fire rated glazing is used to fix these doors to provide additional safety features to resist spreading of smoke and fire. Intumescent Seals used to fix metal fire doors tend to expand during outbreak of fire to avoid circulation of smoke and heat inside fire affected structure.
