Fire Rated Coating For Steel Structure

Provides intumescent fire protection that exceeds many astm e119 listing standards.

Fire rated coating for steel structure.

Thin film intumescent coatings can be either on site or off site applied. 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. Passive fire protection comprises a range of coating systems cladding with fire rated board concrete filling of hollow sections or concrete encasement. Boards and blanket fire protection system.

Active fire protection systems may. Steel is a durable noncombustible fire resistant material. Intumescent coating steel structure fire protection system. Structural steel is the most commonly protected material but protection can include other materials such as sheet metal sheetrock composite panels and interior woods.

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. 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. 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. It is less common to use fire retardant paints for steel structures because they do not have the same insulating properties of intumescent paint.

Sprayed cementitious or gypsum based coatings. Part 4 bs 476. When properly designed and constructed steel framing can preserve its structural integrity in the event of a fire and exposure to prolonged elevated temperatures. All of promat products and systems have been tested at nationally accredited laboratories around the world to a variety of standards including as 1530.

A high section factor gives a quick temperature raise of the steel. This relation is called the section factor a v. 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. Part 21 din 4102 astm e119 and en 13381 8.

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. Active fire protection systems work alongside passive fire protection systems to prevent retard and suppress structural fires. Hp stands for heated perimeter or the portion exposed to fire and a stands for the cross sectional area of the beam. Active fire protection.

In practice this means that thin steel structures demand. 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.
