Ezy-Guard High Containment 


Introducing Ezy-Guard High Containment, a member of the Ezy-Guard family, the next generation steel guardrail barrier providing superior motorist safety with a tested containment of MASH Test Level 4.

Ezy-Guard HC is crash tested to the Manual for Assessing Safety Hardware (MASH) and AS/NZS 3845.1:2015. MASH TL4 is a 58% increase in impact energy when compared to the old NCHRP-350 TL4.

The MASH TL4 crash test matrix requires the following impacts;

• 1,100kg car travelling at 100km/h and 25 degrees.

• 2,270kg pick-up travelling at 100km/h and 25 degrees.

• 10,000kg truck travelling at 90km/h and 15 degrees.

The Z-post profile shields post edges from vulnerable road users and provides sectional strength when driving through difficult conditions.

Offering a greatly reduced footprint of 245mm, compared to the 585mm of Modified Thrie-Beam, the system offers great flexibility to road designers. 

An Ezy-HC-Carriage is used to secure the Thrie-beam rails to the posts, eliminating the requirement for blocking/offset pieces and rail stiffening plates. This unique connection provides a soft ride-down for the occupants and smooth vehicle containment and redirection.

HIGHER PERFORMANCE – LIGHTER  – FEWER PARTS
RAPID INSTALLATION – NARROW WIDTH – CONSIDERATION FOR MOTORCYCLISTS
