The Bristorm Zero Fence itself is comprised of a non-tensioned eight wire-rope system supported by rectangular, hollow section line posts and terminated at anchor posts or intermediate restraint posts. The length of each fence is infinite as long as the maximum distance between anchors is maintained in accordance with manufacturer's installation manual.
All anchors are 2450mm long x ⌀ 406mm with an integrated ⌀ 960mm diameter welded plate positioned at 1200mm. The height of the anchor posts shall be 1200mm from the finished ground level. All anchors are hot-dip galvanised to BS EN ISO 1461 after fabrication. Additional coatings can be applied to achieve specific project coating thickness or aesthetic.
All anchors with the exception of the wrap anchors are considered terminating anchors. All anchor posts are installed into a 2000 x 2000 x 2500mm mass pour concrete foundation. Concrete must be a minimum of C35 SR mix design or site-specific equivalent. A single layer of reinforcement mesh A393 shall be set 100mm below the finished concrete surface. Detailed installation methodology can be found in the manufacturer's installation manual and associated drawings.
The anti-vehicle fence system is crash tested to ASTM F2656-15, successfully achieving M50:P1 and M50:P2. All the steelwork for the fence has been hot-dip galvanised to BS EN ISO 1461, with the strands zinc plated and HDPE coated as per EN 10264-2:2002. Thicker coatings are available and we can powder coat the fence to a specific colour on request.
