- Description DescriptionThe Ezy-Guard HC Safety Barrier is a high-containment steel guardrail system designed to deliver superior motorist safety with enhanced impact resistance. As a member of the Ezy-Guard family, it meets both MASH TL3 and TL4 standards, making it an ideal choice for roadside and median applications requiring robust containment.Description DescriptionFeatures• 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, 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 HC minimises disturbance to the roadside area and conserves valuable formation width.• Consideration for Utilities & Services: Ezy-Guard HC 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 HC may be reduced by decreasing Post Centres below the standard 2m.• Multiple Speed Environments: Ezy-Guard HC is ideally suited to all speed environments up to TL-3 and TL-4.• Proximity to Hinge Point: Ezy-Guard HC may also be used in TL-2 and TL-3 environments 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 HC is ideal for median applications in either single-sided or double-sided layouts, offering effective containment for bidirectional traffic with a streamlined design.• Excess Capacity: Ezy-Guard HC has been successfully tested to meet the requirements of EN1317-2, TB51 which uses a 13000 kg bus impacting at 20 Degrees and 70 km/hr. This represents an increase of 37% in impact severity over the MASH TL-4 test.• Rapid Installation: With fewer parts and no concrete required, the Ezy-Guard HC 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.Description DescriptionAcceptanceThe Ezy-Guard HC Safety Barrier is fully compliant with AS/NZS 3845 Parts 1 and 2 and has been recommended for acceptance by the Austroads Safety Barrier Assessment Panel. It is approved for use at impact speeds up to 100 km/h.Description DescriptionPerformance MetricsMASH TL3 Compliance: Successfully crash-tested with a dynamic deflection of 1.16m, demonstrating the system’s ability to withstand impacts and protect vehicle occupants.MASH TL4 Compliance: Demonstrates the system’s capacity to handle heavier vehicles with a dynamic deflection of 1.20m.
