Rough surface area from total steel weight and section class, and gallons per coat from your coverage rate — for coating quotes and material planning.
Surface-area-per-ton factors are planning assumptions - actual area depends on the section mix. area = tons × class_factor; gal_per_coat = area ÷ coverage. Estimating aid only; the coating spec and applicator govern.
Verify with project engineer, contract documents, and applicable code/specification. Estimating aid only — not a design tool, not legal advice.
