Product Information Product Information
- Description DescriptionDescriptionThe 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 MASH 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 FeaturesFeatures• Crash tested and approved to MASH TL3 and MASH TL4• Designed in accordance with AS/NZS 3845.1:2015 or AS/NZS 3845.2:2017 Road Safety Barrier Systems & Devices• Tested on 1H:1V batter slope• Optional Ezy-Lift carriage for overlays up to +180mm• Rounded and shielded Z-Posts improve safety for pedestrians and motorcyclists• Installation in rock, asphalt, or on concrete mowing strips in accordance with guidance

- What is Ezy-Guard LDS and when would you choose it over other Ezy-Guard systems?View
Ezy-Guard LDS is a MASH TL4 low deflection Thrie beam barrier that uses a Z post and LDS carriage to minimise deflection. It is suited to constrained roadsides, steep batters and locations where there is limited room between the traffic lane and the hazard.
- What is the deflection of Ezy-Guard LDS at TL3 and TL4?View
Under MASH TL3 and MASH TL4 testing, Ezy-Guard LDS achieves a dynamic deflection of 1.1 metres. This reduced movement makes it suitable where clearance to hazards, batter edges or structures is tight.
- How is Ezy-Guard LDS installed — does it drive into the ground like the other Ezy-Guard systems?View
Yes. Ezy-Guard LDS installs the same way as the other Ezy-Guard systems. The Z post is driven directly into the ground using standard guardrail installation equipment. The system relies on the post yielding by bending near ground level, with not on soil rotation, so the installation method remains the same whether you’re using Ezy-Guard 4, HD or HC.
- Can Ezy-Guard LDS be installed at the batter rounding point on a 1H:1V slope?View
Yes. Ezy-Guard LDS has been crash tested to MASH TL3 with posts installed at the rounding point of a 1H:1V batter in standard soil with the extended post and soil plate. Designers still need to check ground conditions and erosion risk and treat this as Extended Design Domain where required by the road authority.
