  • Structural Steel Fireproofing

When steel heats up during a fire, the structure gradually loses its load-bearing capacity at temperatures between 350 ºC to 750 ºC. Depending on the dead load on the structure, it would typically fail when the steel reaches temperatures between 500 to 600 ºC. Therefore, structural steel protection is required to  preserve the stability of the building structure in the event of fire. The required thickness of each product depends on: The fire resistance requirement (typically 60, 90 or 120 minutes, sometimes even 180 or 240 minutes, in accordance with local legislation and mostly depending on the function and height and activities inside the building).
