This type of protection is long-lasting

When the fire rating (or fireproofing) the structural steel in a building, it is best to use thin-film intumescents. These are special coatings that are applied to the surface of the metal which react in the presence of heat and flame to provide an insulated layer over the metal. You must keep in mind that this type of protection is superior to other types of metal protectors, as this type of coating will resist all types of moisture, as well as abrasion. Because this protection is long-lasting, you will not have to re-coat the metal as often — which will significantly lower your building repair and maintenance costs.
