Fire protection of steel structures: Fibrofeu®
Fibrofeu® is a fibrous spray-on mixture used for passive fire protection of steel structures. Fibrofeu® consists of slag wool, with hydraulic and inorganic binders. It is supplied in the form of light ﬂocons. It is used for the fire resistance of steel structures.
Fibrofeu® is a spray-on product. The spraying technique, also known as flocking, consists in applying Fibrofeu® fibres under pressure using special machines.
The product is sprayed to a thickness defined by the desired fire resistance, the section factor and critical temperature of the steel structure.
The spraying machine generally comprises a feed hopper, a carding device, a blowing device (fan, turbine or blower), a hose for conveying the mixture to be sprayed. A spray gun and water.
The product is carded in a machine and then fed through a hose to a spray gun using compressed air. Water-fed nozzles are placed around the hose outlet to wet the product before it is sprayed onto the substrate.
