Target fire resistance durations
- R30
- 30 minutes
- R60
- 60 minutes
- R90
- 90 minutes
- R120
- 120 minutes
The target duration is determined by the product approval document and project calculations. The coating thickness varies according to this duration and the section properties of the element.
Scope of application
The system is not a single layer. Primer, intumescent coating and suitable topcoat work together.
-
01
System selection
Water-based and solvent-based intumescent and passive fire protection coating systems.
-
02
Coating combination
Primer, intumescent coating and suitable topcoat combination is determined according to the project.
-
03
Target duration and approval
Product approval document and calculations based on target durations such as R30, R60, R90 and R120 are taken as basis.
-
04
Thickness calculation
Required DFT is determined according to the section factor (Hp/A), critical steel temperature and manufacturer-approved loading table.
-
05
Record
Coating thickness, curing, mesh or reinforcement requirement and final measurements are recorded.
Standard approach
Fire protection requires a different verification chain than corrosion protection. The product's test document is as decisive as the system itself.
- EN 13381-8
- Determination of the contribution of fire protection systems to steel elements
- EN 13501-2
- Classification according to fire resistance tests
- Hp/A
- Section factor; the geometric ratio that determines the heating rate of the element
- ETA / test report
- Manufacturer approval document and loading table
Depending on project and product approval, EN 13381-8, EN 13501-2 and relevant national or international fire design requirements are taken into account. The final system is verified with the product manufacturer's test and ETA documents and customer specifications.
Frequently asked questions
The most frequently asked questions during the quotation phase. If you cannot find what you are looking for, you can write directly.
It is a thin coating under normal conditions. In case of fire, it expands with heat to form an insulating carbon layer, delaying the temperature increase of the steel supporting element. The aim is to postpone the steel reaching critical temperature for the intended duration.
It expresses the target fire resistance period in minutes: R30 for thirty minutes, R120 for one hundred and twenty minutes. Which duration is required is determined by the project's fire design; the coating thickness varies according to this duration and the element's cross-sectional properties.
The required dry film thickness is determined based on the section factor (Hp/A), critical steel temperature, and the manufacturer's approved loading table. Different sections require different thicknesses for the same target duration; therefore, the element list and section information are important for quotations.
It is the ratio of the cross-sectional area of the element's fire-exposed surroundings to its volume. Elements with a high section factor heat up faster and require a thicker coating. This value is calculated from the element's geometry.
Both are applicable. The choice is made based on the application environment, drying conditions, exposure, and project specifications. The system is not a single layer: depending on the project, primer, intumescent coat, and appropriate topcoat work together.
Depending on project and product approval, EN 13381-8, EN 13501-2, and relevant national or international fire design requirements are considered. The final system is verified with the product manufacturer's test and ETA documents and the customer's specification. Coat thickness, curing, mesh requirements, and final measurements are recorded.
