Fire coating

Structural steel, concrete, wood, textiles and other surface layers

The fire resistance of a structural construction is classified as R30, R60, R90, etc. The letter R stands for Resistance and the number represents the number of minutes that, for example, the construction would stay intact and carry the load in case of a fire.
The amount of fire safety coating applied to meet the prescribed fire protection classification depends on several factors: type of building (one, two or multiple stories) which defines the fire resistance classification; the static utilization of the construction load in the case of a fire; and F/A = the ratio between the surface exposed to fire and the sectional area of the steel profile at hand.
Based on these parameters, the amount of required coating is calculated.
We are authorized to perform fire safety coating with Envirograf HWO1 and HWO2, which provides EI class wood. It will also meet demands for K210 – Bs1do (inflammable surface).
