Crash tested to MASH TL-4, Ezy-Guard™ High Containment (HC) is a guardrail barrier designed to dissipate impact energy as the barrier deflects on impact, reducing occupant risk.
A lightweight guardrail system, fabricated entirely from components that have been hot dip galvanized to EN1461, Ezy-Guard™ HC has ductile Z-posts, which are designed to shield the post edges to protect vulnerable road users and provide sectional strength when motorists are driving through difficult ground conditions.
Ezy-Guard™ HC also features a clever sliding EzyHC-Carriage™, which is used to secure the Thri-beam rails to the Z-posts. The Ezy-Guard™ HC Thri-beam stays constantly engaged with any impacting vehicles, providing excellent containment for vehicles of all types – from cars through to trucks – minimising vehicle damage with reduced ride-down deceleration forces.
The innovative EzyHC-Carriage™ design eliminates any need for blocking pieces and rail stiffening plates, which could cause injury due to scattering debris, improving the safety credentials of the Ezy-Guard™ HC system still further. The supporting Z-posts have also been designed with safety in mind, and have smooth, rounded post edges and corners, eliminating the risk of snagging injuries during or after installation. By positioning the top of the rail above the posts, the revolutionary design of Ezy-Guard™ HC shields the top of the Z-posts too, eliminating another potentially dangerous snag point.
Not only is Ezy-Guard™ HC crash tested to the highest performance standards, the system is also capable of containing and redirecting a 10,000kg truck – a vehicle 2000kg heavier and travelling with 58% more impact forces than the NCHRP-350 TL-4 truck deployed for standard testing.
