Fireproofing is a passive fire protection system intended for structural elements, primarily steel, whose purpose is to limit heat transfer during a fire and delay the material from reaching its critical temperature, thereby ensuring the preservation of load-bearing capacity for the fire-resistance period required by the UL design.

It includes the application of sprayed cementitious coatings, fireproof mortars, intumescent paints, or encapsulated systems designed to achieve specific Fire Resistance Ratings (FRR) in accordance with international standards such as ASTM, UL, EN, and NFPA. These systems enable compliance with required resistance periods, optimize structural performance under fire exposure conditions, and ensure adherence to fire safety regulations in industrial, commercial, and infrastructure projects.
