Intumescent protection,
rated to 120 minutes.
A structural steel coating certified across all three standard fire curves: cellulosic, hydrocarbon and RWS. Under heat it expands into an insulating char that holds the steel below its critical temperature for the rated period. Select a curve to see where it applies.
Cellulosic · peak ~1050°CHydrocarbon · plateau ~1100°CRWS · peak ~1350°C
Three curves, one coating. RWS is the most severe, which is why it defines the tunnel and infrastructure end of the range.
