Construction
Liekkiloukku® has a two-part structure with an SFS-EN ISO 14122 compliant walkway grating and a fire protection element fixed under the grating. The fire protection element is made of sheet metal with four slanted sides and a slotted bottom.
The grating acts as the load-bearing structure while the fire protection element suppresses fires and controls the pressure and flow of liquids.
Thanks to this dual construction, Liekkiloukku® is impact-proof and has excellent fire suppression properties. It also acts as an effective heat exchanger, dissipating the heat released by a fire.
The benefits of Liekkiloukku®
Liekkiloukku® provides a safe and hassle-free walkway and working platform in compliance with the current SFS-EN ISO 14122 standard that also acts as fire protection grating for fires involving liquids. Liekkiloukku® is designed to be self-cleaning, and it stays non-slip even when wet or oily. The structure of Liekkiloukku® redirects streams of liquid, ensuring that all environmentally hazardous substances are safely trapped in the bund underneath.
Liekkiloukku® is made of hot-dip galvanised steel, which makes it easy to dispose of in an eco-friendly manner. Lightweight and robust, Liekkiloukku® can take all kinds of loads and is easy to both install and earth.
Liekkiloukku® significantly improves the fire and occupational safety of transformer rooms – check with your insurance provider if your premiums can be lowered with Liekkiloukku®.
