The most common way of fireproofing is by spraying low-density fibers or cementitious compounds, called spray-applied fire-resistive materials or SFRM. Certified AISC structural steel fabricators are qualified to meet fireproofing needs. The common ratings are 2-, 3-, and 4-hour marks. Commercial structural steel should meet at least the 2-hour fire resistance rating, among other requirements.

Building codes require fireproofing protection for structural steel as a safety precaution.įireproofing steel will ensure a building keeps its shape in the event of a fire, allowing people to escape during an emergency. Consider that the material deforms and loses strength when exposed to high temperatures. The possibility of melting steel is rare, but this does not mean that steel structures are safe. Structural steel melts at approximately 2,500☏, while building fires commonly reach a temperature in the range of 2,000☏. Get a reliable fire protection design, and protect your building and its occupants.

In other words, the item may be damaged by fire that exceeds the intensity or duration for which it was designed. However, it is important to note that items classified as “fireproof” are resistant to a specific circumstance. There are several fireproofing methods used in construction. This is considered a passive fire protection measure. It could be an entire structure, a specific material or some building components. Fireproofing refers to rendering something fire-resistant or incombustible.
