Fire Rated Coating For Steel Structure

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

Fire rated coating for steel structure.

This relation is called the section factor a v. A high section factor gives a quick temperature raise of the steel. Active fire protection systems may. Boards and blanket fire protection system.

Active fire protection systems work alongside passive fire protection systems to prevent retard and suppress structural fires. 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. Intumescent coating steel structure fire protection system. 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.

Structural steel is the most commonly protected material but protection can include other materials such as sheet metal sheetrock composite panels and interior woods. All of promat products and systems have been tested at nationally accredited laboratories around the world to a variety of standards including as 1530. Passive fire protection comprises a range of coating systems cladding with fire rated board concrete filling of hollow sections or concrete encasement. Thin film intumescent coatings can be either on site or off site applied.

Active fire protection. Promat fire rated steel coatings are designed to limit the temperature of the steel during a fire. Part 4 bs 476. Sprayed cementitious or gypsum based coatings.

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. 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.

Hp stands for heated perimeter or the portion exposed to fire and a stands for the cross sectional area of the beam. Steel is a durable noncombustible fire resistant material. It is less common to use fire retardant paints for steel structures because they do not have the same insulating properties of intumescent paint. Structural steel buildings perform well when exposed to fire.

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.
