Fire Resistant Coating For Steel

Fire resistant paint for steel based on 2 technologies.

Fire resistant coating for steel.

Cementitious fire retardant coatings were developed as the lightweight alternative for dense concrete which is the oldest fire retardant coating for steel. Each of these coating types are further divided by the length of time they provide fire protection for 30 60 90 or 120 minutes. Passive fire protection materials insulate steel structures from the effects of the high temperatures that may be generated in 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.

Building regulations require different minimum time. Steel girders and steel supports lose their carrying capacity under load at temperatures above 500 c. They provide the same protection as concrete immune to fire but are much lighter in weight. These coatings are common on structural steel.

Fire resistance is usually measured in relation to the ability of the structural section to survive in a standard fire test as outlined. Fire testing design using structural fire standards all hot rolled structural steel sections have some inherent fire resistance and this is a function of the size of the section its degree of exposure to the fire and the load that it carries. To prevent exceeding of this critical temperature in case of fire effective fire protection is required in the form of a fire protection covering or fire protection coatings. Fire retardant paints are most frequently used in large scale industrial spaces public buildings and facilities or on new builds.

Anti fire paint for metal can be classified by fire protection method. Fire protection coatings advantages beyond fire protection.
