Intumescent Paint For Steel Beams

The flameoff steel coverage calculator is intended to provide the user with an approximate amount of product needed for a project.

Intumescent paint for steel beams. As the temperature rises during a fire event the intumescent coating swells and forms a char layer that covers the steel. The most common use for intumescent paint in architecture is to provide an aesthetically pleasing finish on exposed structural steel members. Fire protection of structural steel is attained by painting the steel structures with a special protective paint an intumescent coating. Watch video 2 min space play pause.

This char layer is of low thermal conductivity thus acting as an insulating system. Product requirements will vary according to factors such as application method surface condition ambient temperature air humidity and many other factors. Steel loses its loadbearing capacity when its temperature rises above 550ºc during a fire. Application of intumescent paint layers helps fireproof structural steel steel beams steelwork or cast iron and can be used externally or internally on small or larger areas.

The intumescent coating expands at high temperatures and forms a protective insulating layer on the surface of the steel. Fireguard e 84 intumescent coating is more cost effective than other solutions without sacrificing protection as low as 0 75 per square foot. Typical spray applied fireproofing provides a thick and spongey surface that requires a finished surround to hide and protect the steel member. As a means of fire protection it presents several advantages.

An intumescent coating is basically a paint like material which is inert at low temperatures under 200 c but reacts with heat. A chemical reaction at about 350 f builds up an insulating char that protects the underlying material from the heat. Intumescent coatings are generally available as water based or solvent based variations more information below. Intumescent paint is a passive fire resistance coating that expands up to 50 times the original thickness when exposed to fire.

Therefore structural steel protection with intumescent coatings is required to preserve the stability of the building structure in the event of a fire.
