Fire Protective Plasters On Structural Steel

By creating an insulation barrier between the heat source and the steel this prolongs the steel from reaching its failure temperature.

Although there are various products available on the market very dense materials (i.e. concrete) tend to spall with rapid temperature rise due to the naturally contained moisture which is transformed to steam during a fire creating pressure within the structure. Medium density material allows the steam to dissipate preventing spalling and providing a more effective barrier system.
