🛡️ UL / ASTM E119 SFRM (W/D Beam & A/P Column Steel Heated Perimeter Heat Sinks)

SFRM Spray-Applied Fireproofing Calculator

Calculate required dry Spray-Applied Fire-Resistive Material (SFRM) thickness for structural steel beams and columns under UL fire resistance designs & ASTM E119: calculate steel section heated perimeter W/D (weight-to-heated perimeter) or A/P ratio, determine exact spray thickness (3/8" to 1-1/2" for 1-hr to 4-hr fire ratings), and fireproofing contractor profits.
