Fire & Finish — SFRM Material Takeoff
SFRM Material Takeoff for steel fire protection and finishing.
SFRM consumption surprises by the overspray line: 25–40% of low-density spray never lands on steel — it lands on the deck, the floor and the dust masks. The density entry matters triple: exterior and high-abuse zones use medium/high-density products at 1.5–3× the mass per millimetre.
Formula
Note: Erection-planning estimate only. Member weights, connection capacities and tolerances for execution must come from the issued drawings, the EOR and the erection engineer — never from a generic calculator.

About Fire & Finish — SFRM Material Takeoff
Fire & Finish — SFRM Material Takeoff computes the governing relationship m = A × t × ρ × (1+overspray) live as you type. SFRM consumption surprises by the overspray line: 25–40% of low-density spray never lands on steel — it lands on the deck, the floor and the dust masks. The density entry matters triple: exterior and high-abuse zones use medium/high-density products at 1.5–3× the mass per millimetre. Defaults are pre-filled with realistic values for this exact scenario, and the worked example substitutes your numbers step by step so the math is never a black box.
How to use Fire & Finish — SFRM Material Takeoff
- 1Enter your values — Steel surface area, Average thickness, In-place density, Overspray/waste (sensible defaults are pre-filled).
- 2Read the live results: Material required, 20 kg bags.
- 3Check the "with your numbers" line to see m = A × t × ρ × (1+overspray) substituted step by step.
- 4Adjust inputs until the scenario matches yours, then copy or share the result.
