Steel Ring Mesh Barrier



Products Specification

Steel Ring Net Panel ——— simple system, maximum safety !

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.

Component

  • Chain link mesh. The chain link mesh are made of high tensile steel wire to bear the high impact from stones or snow. The wire diameter will be 2.5 mm or thicker and the mesh size is commonly 50 mm.
  • Hexagonal wire mesh. It is an alternative to the chain link fence. The hexagonal wire mesh can also be used combined with steel ring net to block the smaller stones or soils in the natural hazard.
  • Steel ring net. Steel ring net is made of high tensile steel wire and the wires are looped into circles. The circles will connect with each other to form steel ring net. The steel ring net has high load capacity and is more flexible than the steel rope net.
  • Decompression ring. Decompression ring is placed along the steel wire ring net. It can reduce the pressure of the steel wire ring net. The decompression ring is made of hot dipped galvanized metal, which has outstanding corrosion and rust resistance.
  • Supporting rope. Supporting rope is mainly used for supporting the wire rope and decompression ring. It is made of stainless steel wire ropes, which has high tensile strength and can bear the huge attack from the stones and snows.
  • Steel column. Steel column is the H type post. It is installed onto the foundation base to support the steel wire ring net. The steel column is corrosion and rust resistance to bear the harsh environments. Additional, the steel column is high tensile strength to support the steel ring net. The arrangement of steel column is based on the terrain and usage environments.
  • Foundation base. Foundation base is used for fasten the steel column onto the ground. The foundation base is hot dipped galvanized to resist the corrosion and rust.

BENEFITS & FEATURES

  • RING NET MADE OF HIGH-TENSILE STEEL. It offers an excellent ratio of weight to resistance and offers the safest protection net on the market.
  • 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.
