  • Description Description
    The Ezy-Guard HD Safety Barrier is a robust steel guardrail system designed to provide superior motorist safety with low deflection performance. Fully compliant with MASH TL3 standards, it offers enhanced protection, efficient installation, and a minimal roadside footprint. The system utilizes a unique Z-Post design that yields above ground upon impact, providing safer and more efficient redirection compared to C-Post systems while reducing occupant risk.

    Features
    • Connection to End Terminals, Transitions & Crash Cushions: at 787mm Rail Height, Ezy-Guard 4 is designed to connect to ET-SS, Trend Median, Ezy-Guard HC, Ingal RBT and QuadGuard M10 enabling complete MASH TL-2 and TL-3 compliance.
    • Narrow System Width: At just 245mm from Face of Rail to Back of Post and a 140mm x 60mm Post Profile, Ezy-Guard 4 minimises disturbance to the roadside area and conserves valuable formation width.
    • Consideration for Utilities & Services: Ezy-Guard HD is available with Surface Mounted Posts and where suitable Posts may be omitted for up to 6m. Engineered Ground Beam designs are available to suit Surface Mounted Posts.
    • Suitable for Reduced Deflection: Deflection values for Ezy-Guard HD may be reduced by decreasing Post Centres below the standard 2m.
    • Multiple Speed Environments: Ezy-Guard HD is ideally suited to all speed environments up to and including TL-3.
    • Proximity to Hinge Point: Ezy-Guard HD has been successfully MASH TL-3 tested on the Hinge Point of a 2H:1V Batter Slope using Extended Length Posts with increased embedment. Refer to our Ezy-Guard LDS system for locations with a 1H:1V Batter Slope.
    • Verge or Median Application: While the majority of installations are located on the verge, Ezy-Guard HD is ideal for median applications in either single-sided or double-sided layouts, offering effective containment for bidirectional traffic with a streamlined design..
    • Rapid Installation: With fewer parts and no concrete required, the Ezy-Guard 4 can be installed quickly, reducing labour costs and time on site.
    • Consideration for Motorcyclists: The unique Z-Post used in all Ezy-Guard systems includes features such as rounded post edges and shielded posts to protect vulnerable road users. Ingal MPR may be installed with Ezy-Guard 4 in addition to Ezy-Guard Post Caps.
