Why steel structure need intumescent fireproof coating?

-Unprotected steel can lead to building construction collapsing in a fire.

It can take just a few minutes for unprotected steelwork in a building to attain temperatures of around 550ºC in a fire. At this temperature, steelwork loses its load bearing capacity and the structure is likely to collapse, giving little time, 15 minutes or less, for people to evacuate and even less time for the fire service to bring the fire under control.

Building regulations and legislation demand fire protection to upgrade the fire resistance of buildings and the range of intumescent coatings can certainly stand the heat. As modern design often involves steel being expressed as an architectural feature, intumescent coatings are frequently the protection of choice.

VIT Paint offers up to and including 120 minutes of fire protection and can be applied both on and off site.
