Changing the concept of how traditional w-beam guardrail works, Ingal Ezy-Guard™ Smart uses a unique ‘Z’ shaped steel post which connects to the w-beam guardrail panel via a slot in carriage. The Ezy-Carriage has the ability to move within the slot on Z-post. An Ezy-Carriage is used to secure the w-beam to Z-posts and eliminate the requirement for blocking pieces and rail stiffening plates. This unique connection provides a soft ride-down for occupants and smooth vehicle containment and redirection.
Designed in Australia, Ezy-Guard™ Smart guardrail crash barriers impose lower forces to the impacting vehicle than traditional guardrail crash barriers. As the crash barrier deflects, vehicle impact energy is dissipated and as a result, reduces occupant risk. The ductile Z-posts provide a forgiving impact, reducing ride-down deceleration forces and minimising vehicle damage.
The Z-post profile shields post edges from vulnerable road users and provides sectional strength when driving through difficult ground conditions.
Ezy-Guard™ Smart has been crash tested and evaluated according to the specifications of the AASHTO Manual for Assessing Safety Hardware (MASH) TL3. In the crash test, Ingal Ezy-Guard™ has demonstrated containment and re-direction of a 2,270kg pick-up traveling at 100km/h and impacting at 25° to the barrier. The MASH specification is an update to and supersedes NCHRP Report 350 for evaluating new safety hardware devices since 2009.
Ezy-Guard™ Smart has been accepted by the road authorities in Malaysia (LLM), Australia, New Zealand, FHWA - USA, Mexico, Canada, Brunei and many other countries.

Ingal Ezy-Guard™ Highway Safety Barrier Features
- MASH TL3 Compliant, crash tested ; hence safety performance is proven
- Narrow system width of only 200mm; hence saves valuable space
- No blocking piece (packer) ; hence easier to install & repair
- Flexible and smooth vehicle containment; hence softer impact to errant vehicle and occupant
- Z-post profile comprises smooth rounded edges and the above ground height of Z-post is lower than w-beam, unlike the traditional U-post; hence reducing the risk to vulnerable road users like motorcyclists, pedestrians and cyslists.
- Energy absorbing, ductile Z-post due to the designed yielding/ bending action; thus reducing the risk from the impact of wheel snaggingon the Z-post
