Intumescent Paint For Steel Beams

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

Intumescent paint for steel beams.

This char layer is of low thermal conductivity thus acting as an insulating system. Intumescent steel protection architectural fire protection for exposed structural steel in interior and exterior applications hilti fire finish 120 cfp sp wb is a high performance water based intumescent fire resistive material or ifrm for architecturally exposed structural steel in interior and exterior applications with approved top coats. An intumescent coating is basically a paint like material which is inert at low temperatures under 200 c but reacts with heat. Steel loses its loadbearing capacity when its temperature rises above 550ºc during a fire.

The intumescent coating expands at high temperatures and forms a protective insulating layer on the surface of the steel. Product requirements will vary according to factors such as application method surface condition ambient temperature air humidity and many other factors. The flameoff steel coverage calculator is intended to provide the user with an approximate amount of product needed for a project. Fire protection of structural steel is attained by painting the steel structures with a special protective paint an intumescent coating.

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 most common use for intumescent paint in architecture is to provide an aesthetically pleasing finish on exposed structural steel members.

As a means of fire protection it presents several advantages. Fireguard e 84 intumescent coating is more cost effective than other solutions without sacrificing protection as low as 0 75 per square foot. Intumescent paint is a passive fire resistance coating that expands up to 50 times the original thickness when exposed to fire. A chemical reaction at about 350 f builds up an insulating char that protects the underlying material from the heat.

Intumescent coating are an increasingly used way of providing passive fire protection to the load bearing structures especially structural steel which is becoming more and more popular in modern architectural design of both industrial and commercial buildings.
