Demountable fencing to secure huge underground gas storage chambers has been created for an EDF Energy site in Cheshire.

Perimeter systems manufacturer Zaun Limited has supplied more than 500 metres of 2.4m-high Duo8 steel mesh fencing panels to the energy giant.

Each panel incorporates a 600mm crank above and sits on fencing posts slotted into sockets, allowing the fence line to be demountable.

The site near Crewe incorporates 11 huge gas storage chambers 200 metres underground, each of which can store around 36 million therms.  One therm is the equivalent to 30 kilowatt hours of energy (kWh).

Zaun provides security fencing extensively across the utilities sector and for other sites of critical national infrastructure.

Duo8 is a twin-wire fencing panel featuring two 8mm horizontal wires that sandwich 6mm vertical wires, which provides a good-looking perimeter that is strong and rigid enough to secure a site from potential trespassers, vandals and thieves.

Each panel is manufactured with a 50mm x 200mm, ideal for use with CCTV camera systems as the open mesh aperture provides excellent through visibility.
