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.
Project challenge
Structural steel protection must be selected against the test standard, steel section factor, exposure, primer/topcoat and target dry-film thickness.
Information to collect
- Steel section type
- Required fire rating
- Indoor or outdoor exposure
- Primer or topcoat system
- Applicable standard
Applicable technical data
| Property | Reported value | Basis |
|---|---|---|
| Intumescent solids / density | 66±3% / 1.30 g/cm³ | Supplied CW-FTHL product summary. |
| Application temperature | 5-40 °C | Supplied intumescent work instruction. |
| System options | Intumescent and non-intumescent | Supplied application work instructions. |
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.
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.

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