Fire Rated Coating For Steel Structure

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.

Fire rated coating for steel structure.

Part 4 bs 476. A high section factor gives a quick temperature raise of the steel. Active fire protection systems may. Passive fire protection materials insulate steel structures from the effects of the high temperatures that may be generated in fire.

Structural steel buildings perform well when exposed to fire. They can be divided into two types non reactive of which the most common types are boards and sprays and reactive of which thin film intumescent coatings are the most common example. Hp stands for heated perimeter or the portion exposed to fire and a stands for the cross sectional area of the beam. How quickly the steel structure heats up in a fire can simply be described as the relation between the surface exposed to the fire and the steel volume of the profile.

Thin film intumescent coatings can be either on site or off site applied. Boards and blanket fire protection system. Provides intumescent fire protection that exceeds many astm e119 listing standards. Steel section factor which is simplified as hp a is a ratio that indicates the heating rate of a structural steel section in case of the occurrence of a fire.

Active fire protection systems work alongside passive fire protection systems to prevent retard and suppress structural fires. Part 21 din 4102 astm e119 and en 13381 8. Structural steel is the most commonly protected material but protection can include other materials such as sheet metal sheetrock composite panels and interior woods. Fire retardant paint for steel a fire retardant paint for steel works by releasing a fire damping gas when heated which prevents the spread of flame across a surface usually walls and ceilings.

Sprayed cementitious or gypsum based coatings. All of promat products and systems have been tested at nationally accredited laboratories around the world to a variety of standards including as 1530. This relation is called the section factor a v. Passive fire protection comprises a range of coating systems cladding with fire rated board concrete filling of hollow sections or concrete encasement.

Intumescent coating steel structure fire protection system. Promat fire rated steel coatings are designed to limit the temperature of the steel during a fire. Active fire protection. When properly designed and constructed steel framing can preserve its structural integrity in the event of a fire and exposure to prolonged elevated temperatures.

In practice this means that thin steel structures demand. This type of fire protection system as shown in figure 2 is widely used due to several reasons such as it is clean cost effective water resistant and can be applied to non painted steel members.
