Structural steel

Steel
The thermal effects of a fire on a steel structure result in the temperature in the material steadily climbing, which reduces steels load bearing capacity therefore the structural steel has to be insulated. The use of steel in load bearing struc-ture has increased considerably in modern buildings, which has led to an increase in the number of fire insulation systems. To insulate with our expanding fire retardant paint instead of lagging the construction means that the required fire resistance is achieved without affecting the aesthetics of the structure.
The intumescent paint Novatherm 4FR foams into a thick layer when exposed to high tempera-tures derived from flames or intensive heat radi-tion from fire. The porous layer of foam effectively extinguishes the flow of heat to treated structure.
