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.
