Fire & Finish — Galvanizing Field Repair
Galvanizing Field Repair for steel fire protection and finishing.
Every field weld on galvanized steel burns its own repair zone — ASTM A780 allows zinc-rich paint (cheap, thinner protection), solder sticks, or metallizing (best, priciest). Designs that bolt instead of field-weld galvanized work delete this line item entirely.
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 — Galvanizing Field Repair
Fire & Finish — Galvanizing Field Repair computes the governing relationship cost = area × method rate ($45/$120/$220 per m²) live as you type. Every field weld on galvanized steel burns its own repair zone — ASTM A780 allows zinc-rich paint (cheap, thinner protection), solder sticks, or metallizing (best, priciest). Designs that bolt instead of field-weld galvanized work delete this line item entirely. 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 — Galvanizing Field Repair
- 1Enter your values — Damaged area (welds, cuts, scrapes), Method (1 zinc-rich paint · 2 solder stick · 3 metallize) (sensible defaults are pre-filled).
- 2Read the live results: Repair cost estimate.
- 3Check the "with your numbers" line to see cost = area × method rate ($45/$120/$220 per m²) substituted step by step.
- 4Adjust inputs until the scenario matches yours, then copy or share the result.
