A
key customer requirement has driven a steel mesh fencing manufacturer to a
probable world-beating performance in security tests.
A
development fencing system based on Zaun Ltd’s CorruSec resisted serious
attempts at forced entry for over 20 minutes with tools including reciprocating
saws and angle grinders in independent tests by Buildings Research
Establishment (BRE) assessors.
“We
believe this may be a world record for a fencing system,” said Zaun founder and
director Alastair Henman on returning from the test.
Independent
testers from BRE mounted a sustained attack on the Zaun development fence,
loosely based on an SR5 ‘serious attempt at forced entry’.
They
used top end battery power cutting tools including an awesome 750W
reciprocating saw with specialist blades used by fire and rescue teams and 18V
circular saws, jigsaws and disk grinders, axes including an 850mm felling axe,
a hooligan bar, 1.5kg lump hammer and 500mm long bolt cutters.
They
were trying to create a ‘man-sized’ 600mm square hole in the fence line –
larger than the 450mm x 225mm that is part of the SR5 test.
Henman
said: “Even with this astonishing arsenal, testers took more than 20 minutes to
create this larger breach. The fence, which uses a clever combination of
materials and geometry to maximise resistance, needed to survive for only 10
minutes to pass the client’s test.”
CorruSec
variants had already achieved official SR3 and SR4 ratings.
