Fire Rated Coating For Steel Structure

This relation is called the section factor a v.

Fire rated coating for steel structure.

Part 4 bs 476. 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. Hp stands for heated perimeter or the portion exposed to fire and a stands for the cross sectional area of the beam. Part 21 din 4102 astm e119 and en 13381 8.

Active fire protection systems may. Structural steel buildings perform well when exposed to fire. 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. 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.

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. All of promat products and systems have been tested at nationally accredited laboratories around the world to a variety of standards including as 1530. When properly designed and constructed steel framing can preserve its structural integrity in the event of a fire and exposure to prolonged elevated temperatures. Active fire protection.

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 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. Passive fire protection comprises a range of coating systems cladding with fire rated board concrete filling of hollow sections or concrete encasement. It is less common to use fire retardant paints for steel structures because they do not have the same insulating properties of intumescent paint.

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. Boards and blanket fire protection system. A high section factor gives a quick temperature raise of the steel. In practice this means that thin steel structures demand.

Passive fire protection materials insulate steel structures from the effects of the high temperatures that may be generated in fire. Promat fire rated steel coatings are designed to limit the temperature of the steel during a fire. Intumescent coating steel structure fire protection system. Active fire protection systems work alongside passive fire protection systems to prevent retard and suppress structural fires.

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