RHINO-STOP® Guardrail FAQs

All RhinoStop® barriers incorporate a unique patented yielding base plate that minimises the peak loads transferred to the post anchors. The yielding behaviour of the base plate absorbs vehicle impact energy and prevents damage to the concrete substrate.

RhinoStop® has been crash tested to validate compliance with the 30kN (Type F) vehicle impact load described in AS/NZS 1170.1, Clause 3.8.

Crash testing was performed with the RhinoStop® system positioned on the edge of a 150mm thick, suspended concrete slab.

A 1500kg passenger car travelling at 15km/h was impacted on one (1) w-beam guardrail panel supported by three (3) RhinoPosts®. The height of impact was 0.5m above ground level.

Safe Direction’s crash test evaluation is designed to represent the worst, or most critical, impact conditions when evaluating RhinoStop®:

• The RhinoPosts® are installed on the edge of 150mm thick, suspended concrete slab, thoroughly evaluating the potential for concrete edge failure and the suitability of the anchor embedment depth.
• Vehicle impacts are performed at up to twice the speed nominated by AS/NZS 1170.1.
• Short-length barrier systems, designed to distribute the impact load on fewer posts and produce the largest system deflection.

A minimum three (3) RhinoPosts® are required per installation.

The spacing between the RhinoPosts® shall not exceed 2m.

RhinoStop® features an all-steel construction, with hot dip galvanised RhinoPosts® and w-beam guardrails.
