Chain Link or Hexagonal Wire Mesh Combination.
The Ring Netting Protection System is passive protection system which protects against impact energies of up to 500 kJ with extremely low anchoring forces and uniform energy absorption to the boundary of the fence. Combined with a quick and simple installation this ring net barrier is both, cost-effective and efficient.
For uses where the rockfall protection system may need to withstand high static and dynamic stresses, HESLY proposes rockfall panels, referred to as Ring Net Panels. These typically consist of 14 in (35 cm) diameter ring nets consisting of a high strength steel wire coil. Each ring is intersected by another 4 or 6 adjoining rings to form ring net panels with a different number of rings, therefore, different dimensions. The ring nets are typically used for the facing of rock slopes subject to the falling of large masses, where the local stresses on the panel reach very high peaks, but without suffering appreciable damage.
SIMPLE CONSTRUCTION. The extremely simple and well-thought-out construction permits a very fast installation as well as low material and maintenance costs.
PRE-ASSEMBLED. The posts are delivered to the construction site as modules with pre-installed bundles of netting for easy installation. This significantly reduces the installation time.
ONE-FIELD BARRIERS WITH FULL ABSORPTION CAPACITY. Modifications for short barriers are unnecessary: RXE-500-LA is also a cost-effective one-field solution and the system is quickly installed.
FIRST-CLASS CORROSION PROTECTION. The corrosion protection of our systems will last for generations. This means that our customers benefit from particularly low maintenance costs.
