Steel Ring Net with High Load Capacity for Stone Blocking

Four continuous steel wire ring net used individually for rockfalls blocking.

Combined with chain link or hexagonal wire mesh fence, steel wire ring net offers customers best solution for mountain or slope rockfalls blocking.

Steel ring net system, made of high tensile steel wires, is a kind of passive rockfall barriers. There are four contiguous ring and six contiguous ring types. The steel ring net is more flexible than the steel rope net. With high loading capacity and excellent buffering performance, passive rockfall barrier is often combined with chain link or hexagonal wire mesh and installed at the bottom of mountains or slopes to block the stones then reduce the impact of the rockfalls and protect the safety and property of people.
