Fire Rated Coatings For Steel

Passive fire protection materials insulate steel structures from the effects of the high temperatures that may be generated in fire.

Fire rated coatings for steel.

Thin film intumescent paint for steel. Insulating the structural steel. 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. Structural steel is the most commonly protected material but protection can include other materials such as sheet metal sheetrock composite panels and interior woods.

Intumescent coatings are the best example and come in variants of thin film and thick film types. 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. With all of the benefits of intumescent coatings combined it s our recommended method of fireproofing 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.

These paints are mainly used for providing 0 5 h 1 h and 1 5 h fire resistance. 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. Provides intumescent fire protection that exceeds many astm e119 listing standards. These paints are mainly used for 30 60 and 90 minutes.

Intumescent paint for steel is the main fire protection paint for steel as it provides protection from heat as well as flame. Thin film materials have a 50 1 expansion ratio. These coatings allow for fire ratings of up to four hours. Thin film intumescent coatings can be either on site or off site applied.

Intumescent coatings are epoxy based paint like mixtures applied to the primed steel surface. Find fire resistant coating for steel products and service in qatar. A 1 mm thick coating will expand to about 50mm in a 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.

These coatings are both solvent and water based and are available in a range of finishes. 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.
