Steel Wire Ring Net - Chain Link or Hexagonal Wire Mesh Combination

Steel ring net system is passive protection system. The steel ring net system main consists of steel ring nets and chain link fences. Sometimes, the steel wire ring net can be used with hexagonal wire mesh. The steel wire ring net is combined with several steel rings. The steel rings are made of high tensile steel wires. Single steel wire are looped with ends inserted into the thread or secured by one or more than one ferrules. The ferrules can be steel or aluminum alloy. They are distributed on the rings evenly on three points. The rings are interlocked each other to supply high bear and load capacity. Each ring is connected with four or six contiguous rings in order to create a stable and solid ring net. The steel ring net is more flexible than the steel rope net.

Component

• Chain link fence. The chain link fence 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.

Applications of steel ring net

• The steel wire ring net is mainly used for retaining of unstable slopes controlling and preventing rockfalls and loose debris flow along roads, highways and railway, urban areas, mines and quarries.

• The steel wire ring net can also be used for snow avalanche protection produced from metallic coated steel wire or advanced metallic coating.
