Fire Rated Coating For Steel Structure

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.

Fire rated coating for steel structure. In practice this means that thin steel structures demand. Active fire protection systems work alongside passive fire protection systems to prevent retard and suppress structural fires. Sprayed cementitious or gypsum based coatings. Hp stands for heated perimeter or the portion exposed to fire and a stands for the cross sectional area of the beam.

Passive fire protection materials insulate steel structures from the effects of the high temperatures that may be generated in fire. 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. Provides intumescent fire protection that exceeds many astm e119 listing standards. When properly designed and constructed steel framing can preserve its structural integrity in the event of a fire and exposure to prolonged elevated temperatures.

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. Structural steel buildings perform well when exposed to fire. Steel is a durable noncombustible fire resistant material. 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.

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. Active fire protection. Part 21 din 4102 astm e119 and en 13381 8.

Passive fire protection comprises a range of coating systems cladding with fire rated board concrete filling of hollow sections or concrete encasement. Active fire protection systems may. Intumescent coating steel structure fire protection system. 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 fireproof paint materials that can be used for steel are water or solved based and are typically applied to prevent fires in regular buildings. A high section factor gives a quick temperature raise of the steel. It is less common to use fire retardant paints for steel structures because they do not have the same insulating properties of intumescent paint. Boards and blanket fire protection system.

Thin film intumescent coatings can be either on site or off site applied. Part 4 bs 476.
