Steel is strong and durable, but in a fire it quickly loses its structural strength. At high temperatures, steel can soften and deform, increasing the risk of collapse. Vermiculite coating plays a vital role in fire safety by acting as a passive fire protection layer that insulates steel structures and slows down heat transfer during a fire.http://www.jpscsolutions.com/fire-proofing-of-steel-structure/
