In the process of fire rating the structural steel used in a buildings construction, specially formulated paints are applied to the surface of the metal. This paint is designed so that, in the event of a fire, it will form a charred layer — and this layer will actually serve to protect and insulate the steel, so that it will not heat up too quickly. Why is this important? Because if the metal gets too hot, it will lose its structural strength and begin to buckle, twist, or give out altogether — and if this happens during a fire, it could result in the injury and even death of many people. Think of it this way: this is paint that could someday save your life!
