Car park barriers are a specific range of safety barrier systems designed for the protection of people, buildings, plant and equipment. Their design and function are specific to vehicle movements encountered in a car park or warehouse/industrial environment.
Verge posts are significantly stronger than a similarly sized and anchored rigid post. The vulnerability of rigid posts is the high peak load transferred to the anchors upon vehicle impact typically resulting in anchor failure. All Verge Stop barriers incorporate a unique patented yielding base plate that minimises the peak loads transferred to post anchors.
The defining feature of Verge Stop posts are the long
cuts in the base plate breaking the plate into three fingers connected by a common stem.
The fingers allow the mounting of the post upright to be
separated from the anchor(s). Upon impact from a vehicle, a plastic hinge will form at the location where the fingers that the post is mounted to begins to rotate backwards.
This deformation serves two primary functions:
The various Verge Stop systems have been crash test validated at impact speeds and loads well in excess of those stipulated in AS/NZS 1170.1
Compliant to the 40kN impact load (Type G) described in AS/NZS 1170.1: Structural Design Actions
All Verge Stop systems comply with or have accessories to comply with AS/NZS 2890.1 and the Building Code.
All Verge Stop systems comply with or have accessories to comply with anti-climb requirements of the Building Code.
W-Beam guardrail is the world’s most widely specified safety barrier system and is frequently used in Sydney, NSW, Australia. It comprises steel posts that support a w-beam rail element. Safe vehicle containment and redirection is developed through a combination of the flexural resistance of the rail and the bending resistance of the posts.
Our guardrail designs are manufactured in accordance with Australian state road agency designs. Designs vary from state to state. The most common is a w-beam guardrail supported by a c-post and steel blocking piece.
Safe vehicle containment and re-direction is developed through a combination of the flexural resistance of the w-beam guardrail and the bending resistance of the supporting posts.
Upon impact, the posts absorb some of the crash energy through post rotation in the surrounding soil prior to separation from the guardrail as they fully yield. The blocking pieces, positioned between the guardrail and posts, minimise vehicle snagging and reduce the potential for the vehicle to vault over the barrier by maintaining rail height during the initial stages of impact.
Once the guardrail separates from the posts, the rail forms a re-directive ribbon, guiding the vehicle away from the nearby hazard.
Manufactured in accordance with state road agency specifications.
Hot dip galvanised components in accordance with AS/NZS 4680.
The high visibility of w-beam creates driver confidence.
The post and block design reduces vehicle vaulting or rollover.
