Intumescent Paint For Steel Fire Rating

Structural steel is the most commonly protected material but protection can include other materials such as sheet metal sheetrock composite panels and interior woods.

Intumescent paint for steel fire rating.

The swelling reaction starts usually at about 200 f and the coating can expand up to 50 times its thickness. Exterior intumescents also serve well in locations with tight space restrictions like elevator shafts where a thinner alternative option to conventional cementitious fireproofing is desired. Thin film fireproof paint materials that can be used for steel are water or solved based and are typically applied to prevent fires in regular buildings. Thus intumescent paint for steel is a fire barrier coating which in the event of fire forms a non conductive carbon char to insulate the steelwork from the heat and flames.

Water based and non toxic this fire retardant fire resistant coating is applied just like standard paints by rolling brushing or spraying and can create a fire rated wall for your structure in as. We manufacture an outperforming flameoff fire resistant paint tested to astm e84 and e119 standards and flameoff fire retardant spray tested to nfpa 701 standards. Flameoff fire barrier paint is an intumescent paint that can be applied to most building materials. Intumescent paints for structural fire protection the most common use for intumescent paint in architecture is to provide an aesthetically pleasing finish on exposed structural steel members.

Fire rated intumescent paint is the most commonly used coating to protect steel against fire and acts as an insulator forming a solid char in response to heat intumescent paint can be applied on steel as a thin or a thick film coating. Typical spray applied fireproofing provides a thick and spongey surface that requires a finished surround to hide and protect the steel member. Fireguard e 84 intumescent coating is more cost effective than other solutions without sacrificing protection as low as 0 75 per square foot. Exterior intumescent coatings are used in heavy industrial environments or when steel is located on the outside of a building and still needs a fire rating.

Fire rated designs using thin film intumescent coatings are valid for use in commercial institutional light industrial and residential build ings in canada and the designs tabulated in sds. The final decision about required dft fire ratings needed and an amount of product required to achieve needed fire protection of your project is made between your building official and your fire marshall based on thorough review of flameoff full scale fire testing reports from accredited fire laboratories which can be provided to flameoff.
