High tensile Double twisted hexagonal wire mesh can also be used as rockfall mesh, or rock fall protection mesh, rockfall netting, rockfall fence, rockfall barrier, used mainly in SNS (safety netting system) active protection system.
Due to its high tensile property, firm structure, and various mesh siezs, it is used to prevent loose rocks from falling onto roads, railways and other structures. Anchored to rock face to contain rockfalls. The double twist mesh design can withstand huge forces and will not unravel even if a strand of wire is broken. Its high mechanical resistance reduces the danger of sudden rock shock loads and dissipates rock fall energy created from loose fractured rock.
Usually the rockfall mesh is in hot-dipped galvanized wire. In severely corrosive environments or in seaside locations, heavily zinc-coated steel wire and PVC-coated wire mesh is highly recommended. This has been extensively tested on gabions and Reno mattresses.
