Project Challenge
Structural steel protection must be selected against the test standard, steel section factor, exposure, primer/topcoat and target dry-film thickness.
Application Guide
Fire Protection Coating Systems for Structural Steel
Cowin Materials supplies intumescent and non-intumescent coating products for evaluation in structural steel fire protection systems. Required dry film thickness and system selection depend on the steel section factor, fire resistance period, primer, topcoat and applicable test standard.

System Limits
- No time rating is published without a matching approved report and fully tested system configuration.
- Do not specify fire protection from density, solids content or generic thickness alone.
Verification Steps
- Collect steel section, target standard, exposure class and primer/topcoat proposal.
- Define dry-film build using relevant approved evidence.
- Measure dry-film thickness and curing against the project inspection plan.
Documentation and project review
Request the technical document set for the selected product grade, then verify it against the substrate, test method, system build and operating conditions.

Can you quote a fire rating from the product name?
No. The applicable report, steel configuration, coating build and standard must be confirmed first.
