SFRM Spray Fireproofing Estimating
Spray-applied fire-resistive material is the primary passive fire protection system for concealed structural steel in commercial construction, achieving one to four hour fire-resistance ratings per ASTM E119 and UL 263. We estimate SFRM from your structural drawings and fireproofing specification, calculating coverage area by member type, required thickness per UL design assembly by fire-resistance rating, density category by application environment, and material quantity by coverage rate, organized by floor level and structural zone for direct subcontractor pricing.
