1.0 Introduction
Introducing Ezy-Guard 4, a member of
the Ezy-Guard family, the next generation
steel guardrail barrier providing superior
motorist safety and more metres of
barrier for your dollar.
Ezy-Guard 4 is crash tested to the latest
performance standard distinguishing
it from the existing Australian public
domain guardrail barrier system.
The Z-post profile shields post edges
from vulnerable road users and provides
sectional strength when driving through
difficult conditions.
An Ezy-Carriage is used to secure the
w-beam rails to the posts eliminating
the requirement for blocking pieces
and rail stiffening plates. This unique
connection provides a soft ride-down
for the occupants and smooth vehicle
containment and redirection.
