The bill is set by litres, not square metres alone
Coating volume = area × dry film thickness ÷ volume solids. Area comes from the member list, thickness from the rating and section factor, volume solids from the product data sheet. Labour, primer, topcoat and inspection come on top.
The big levers
- Rating – 2 hours can cost several times 1 hour
- Section factor – slender members need much more film
- Critical temperature – a calculated value usually beats the default
- Where it is applied – plant application avoids site access and weather costs
- Exposure – coastal or semi-exposed steel needs tougher systems and topcoats
Getting a firm price
Use the estimator on this page with your own peso unit prices for a first idea. For a firm figure, send the structural drawings and the fire safety plan: we return a DFT schedule, coating volumes and a price included in the CIF or DDP offer for the steel.
FAQ
Is intumescent cheaper than boarding?
For 1 to 2 hours on exposed steel it usually is. For longer ratings compare both.
Do you quote coating separately from the steel?
We can, but quoting both together lets us optimise section sizes against coating cost.
Preliminary calculations are provided for estimation purposes only. Final coating thickness and fire protection system selection must be verified against the approved product documentation, applicable project requirements and relevant engineering assessments.
