Plates and nails for the HPN System

Print PDF

The HPN System is a complete kit configurable with various types of plates for anchoring  and tensioning the panels to the ground, allowing for the efficient dissipation of the forces carried by the high performance net.

The rectangular spike plates are used for interventions in loose ground (HPN soil) while the square continuity plates (with wire rope clips) are used for interventions in solid rock (HPN rock).

If it is necessary, we offer plates which can fix the netting with optional ropes, increasing the capacity for retaining the underlying material.  Each plate is anchored to the ground with steel piles such as Gewi, Dywidag or self-drilling anchors.
