Fire Rated Coatings For Steel

When subjected to high heat these coatings expand to many times their original thickness forming an insulating blanket that protects the steel member from heat.

Fire rated coatings for steel. These coatings allow for fire ratings of up to four hours. With all of the benefits of intumescent coatings combined it s our recommended method of fireproofing steel. Insulating the structural steel. Thin film fire rated coating for steel systems generally have three components a primer a basecoat and a sealer coat.

A 1 mm thick coating will expand to about 50mm in a fire. Intumescent paint for steel is the main fire protection paint for steel as it provides protection from heat as well as flame. Intumescent coatings are epoxy based paint like mixtures applied to the primed steel surface. Intumescent coatings are the best example and come in variants of thin film and thick film types.

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. 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. These paints are mainly used for providing 0 5 h 1 h and 1 5 h fire resistance. Hilti fire finish 120 cfp sp wb is a high performance water based intumescent fire resistive material or ifrm for architecturally exposed structural steel in interior and exterior applications with approved top coats.

Passive fire protection materials insulate steel structures from the effects of the high temperatures that may be generated in fire. These coatings are both solvent and water based and are available in a range of finishes. Intumescent coatings fight corrosion in much the same way as traditional protective coatings the difference being their ability to swell and the much greater thicknesses at which they are initially applied. Structural steel is the most commonly protected material but protection can include other materials such as sheet metal sheetrock composite panels and interior woods.

Provides intumescent fire protection that exceeds many astm e119 listing standards. Find fire resistant coating for steel products and service in qatar. 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.

These paints are mainly used for 30 60 and 90 minutes. Thin film materials have a 50 1 expansion ratio.
