  • Description Description
    The Ezy-Guard LDS Safety Barrier is a low-deflection steel guardrail system engineered to provide exceptional motorist safety with advanced impact absorption. Fully compliant with MASH TL3 and TL4 standards, it offers superior containment and redirection for roadside applications. The system utilizes a proven Thriebeam guardrail secured to a sliding carriage mounted on a unique Z-Post. Unlike C-Post and open-profile post designs, the Z-Post is designed to yield above ground upon impact, releasing the carriage and allowing the Thriebeam rail to control and redirect errant vehicles safely and efficiently while minimizing ride-down deceleration forces.

    Features
    Connection to End Terminals, Transitions & Crash Cushions: at 980mm Rail Height, Ezy-Guard HC is designed to connect to ET-SS, Trend Median, Ezy-Guard 4, Ezy-Guard HC, Ingal RBT and QuadGuard M10 enabling complete MASH TL-2 and TL-3 compliance while also providing MASH TL-4 compliance for the Intermediate Barrier.
    Narrow System Width: At just 245mm from Face of Rail to Back of Post and a 140mm x 60mm Post Profile, Ezy-Guard LDS minimises disturbance to the roadside area and conserves valuable formation width.
    Consideration for Utilities & Services: Ezy-Guard LDS is available with Surface Mounted Posts and where suitable Posts may be omitted for up to 4m. Engineered Ground Beam designs are available to suit Surface Mounted Posts.
    Suitable for Reduced Deflection: Deflection values for Ezy-Guard LDS may be reduced by decreasing Post Centres below the standard 2m.
    Multiple Speed Environments: Ezy-Guard LDS is ideally suited to all speed environments up to and including TL-3 and TL-4.
    Proximity to Hinge Point: Ezy-Guard LDS may also be used in TL-2 and TL-3 environments on the Hinge Point of a 1H:1V Batter Slope using Extended Length Soil Plated Posts with increased embedment.
    Verge or Median Application: While the majority of installations are located on the verge, Ezy-Guard LDS is ideal for median applications in a single-sided layout, offering effective containment for bidirectional traffic with a streamlined design.
    Rapid Installation: With fewer parts and no concrete required, the Ezy-Guard LDS system 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 HC in addition to Ezy-Guard Post Caps.
