Gas network turns to prison style security
One of the UK’s largest gas distributors has
specified prison-style double skin steel mesh
and special fence toppings to secure its gas
distribution network across the north of England.
They have turned to PSSA member Zaun
group and its HiSec DualSkin and Flexible
Steel Topping (FST) products.
The distributor delivers gas to 2.7 million
homes and businesses and around 6.7 million
individuals in the North East, Northern
Cumbria and much of Yorkshire through a
vast network of 37,000km of gas pipes –
enough to stretch from Leeds to Sydney,
Australia and back again!
During periods of peak demand, the
network transports four times as much energy
as the electricity networks to large cities
such as Newcastle, Sunderland, Leeds, York,
Hull and Bradford and beautiful rural areas
including North Yorkshire and Cumbria.
Zaun’s HiSec DualSkin has been specifically
designed for sites that need a more secure
solution and features two layers of the
traditional HiSec 358 welded mesh with
76.2mm x 12.7mm open mesh sections.
These double skin 358 panels are welded
together with the secondary panel turned
90 degrees to make a very tight 12.7mm x
12.7mm mesh configuration, which is difficult
to cut and almost impossible to climb.
The tiny apertures eliminate foot and finger
holds for people trying to climb or gain access
to the site, prevent objects being passed
through and are highly resistant against the
use of hand or power cutting tools.
HiSec DualSkin conforms to BS1722 Part 14
Category 4 and has been extensively used in
prisons and by the Ministry of Defence (MoD)
to protect high security assets.
The FST topping system that tops the
fence is fully tested for use in UK high security
prisons. At the heart of FST is a steel mesh arch,
curved back over the top of a steel fence, fixed
to a flexible steel bracket that is designed to
move when people try to climb it.
Zaun opens gates to ThamesWater
Perimeter fencing expert Zaun has installed
trackless bi-folding automatic speed gates at
a Thames Water administration building.
The vehicle gates – which incorporate
live-monitored safety edges, dual height
safety photocells and manual-disengaging
vertical infill bars – have replaced old rising
arm barriers at Kemble Court, Thames
Water’s Operations Management Centre
in Reading.
The PSSA member also installed an adjacent
pedestrian turnstile with a passage for bicycles
and integrated the installation into existing
fencing with 1.8m high HiSec fencing.
So pleased are Thames Water with the
vehicle gate solution that they have specified
it for one of their many sewage treatment
plants, at East Hyde in Luton, that operates
a combined heat and power (CHP) unit to
generate the electricity the plant needs.
The CHP process ‘brews and chews’ sewage
sludge to break down biodegradable material
creating biomethane, or biogas, while
methane from the sludge is burned to create
heat, which in turn generates renewable
electricity using a pre-treatment process
called thermal hydrolysis.
