In today’s modern construction, life safety is critical in building design. Sprayed-on fireproofing systems are a low-cost way to fulfil the hourly ratings necessary by local building regulations and insurance companies. Fireproofing systems can offer structural members a four-hour rating, preventing the steel from collapsing during a fire.

In the event of a fire, fireproofing is a passive sort of protection that is always ready to protect the steel and, ultimately, lives. Passive systems are always present, as opposed to active systems, such as sprinklers, which must be activated before they may function.

The most popular type of fireproofing material is spray-applied fireproofing. Spray-applied fireproofing can be either cementations (gypsum-based, wet mix formulation) or sprayed fibre fireproofing (mineral wool fibre with a portland cement-based binder, dry mix formulation).

Spray-applied compounds are available in standard and high density for concealed applications, as well as medium and high density for exposed applications where the fireproofing is constantly vulnerable to abuse and/or moisture.

For establishing a fire rating on exposed structural steel, intumescent coatings are becoming increasingly popular. Intumescent fireproofing by local fireproofing contractors in Sydney is a type of thin film coating designed for exposed applications where aesthetics is critical. This fireproofing is available in solvent and water-based formulations and has a three-hour rating on beams and columns.

These coatings can be utilised for both interior and exterior fireproofing applications, giving an aesthetically acceptable solution to fireproof structural steel to the owner and architect. To match practically any desired hue, the product can be top-coated with a tinted coating.
