Steel retains approximately 50% of its strength when it reaches 1100°F (600°C). Temperatures during fires can be much hotter – a standard fire test reaches 1300°F (704°C) in the first 10 minutes. If left unprotected, the structure may collapse when exposed to fire.
Building codes require certain beam, column, floor, wall and roof assemblies to have fire resistance ratings which are determined on the basis of standard fire tests. Fire resistance ratings can be accomplished with the application of sprayed fire resistive materials (fireproofing) to those assemblies.
Fire-proofing is a passive action to prevent or delay the transfer of thermal energy to the structural steel by use of protective materials. By fire-proofing the steel in the building will provide valuable egress time for both occupants and firefighters in the event of a fire.
There are two types of spray-applied fire-proofing – cementitious and mineral-fiber sprayed products. Both provide valuable protection to the steel and to the building.
Spray-applied fire resistive materials can provide the following benefits:
- Added Thermal and Acoustical Properties – Offers an average insulation R-value of 3 per inch, as well as sound-absorbing qualities idea for high-noise levels.
- Quick and Easy Application – Spray-applied in one application that requires no pre-mixing thus reducing installation time and labor costs.
- Environmentally Friendly – High recycled content, mold and mildew resistant, non-corrosive on steel, non-combustible, and meets Leadership in Energy and Environmental Design (LEED) Green Building Council standards.
We have all the right tools to effectively and economically fire-proof any type of steel structure that requires passive fire protection. Our certified installers have been trained to properly fire-proof steel structures to provide you with a quality product.
