How does a fire-resistant coating work?
Most are intumescent coatings – a type of flame-retardant paint that swells at high temperatures to form an insulating layer. This layer slows the heating of the steel or concrete underneath, allowing the load-bearing structure to hold out longer. That “time gain” is crucial: it enables safe evacuation and intervention. The required protection is expressed in minutes (e.g. RF30, RF60, RF120), depending on the building type and function. The thickness of the fire-resistant layer depends on that standard and the steel section’s profile thickness.
Fire-resistant systems aren’t off-the-shelf solutions. They are prescribed based on a fire safety study and are often mandatory in, among others:
They often form part of a broader passive protection solution, in combination with compartmentation, fire doors or other measures.
