GTI Rock fall Steel Wire Netting are factory manufactured rolls made up of mechanically double twisted hexagonal wire mesh using Heavily Galvanized steel wire. Mechanically woven double twisted meshes are non raveling and the edges of the mesh are reinforced with a thicker wire called the selvedge/edge wire. These nets are used to prevent small size boulders or rocks from falling in rail or road ways, thus minimizing loss of property or life. In case of applications in marine or highly corrosive environment, an additional protection is provided by extruding 0.5mm thick PVC coating over the heavily galvanized wire.
The main advantages over other types of mesh are the features of flexibility, non-raveling design, superior corrosion resistance and unique mechanical characteris
Rock fall protection can be dealt with in two ways
By curtain meshing the rock faces.
By catch walling.
By curtain meshing the face, spalling rocks can be either held in place by pinning the mesh to the rock strata or by draping it over the face guiding the falling rocks harmlessly to the base of the escarpment.
The mesh facing normally has vertical and/or horizontal cabling secured to the mesh/rock to provide fixity and integrity to the jointing of the panels. It is normal to seek advice from specialist installation companies as to the design of this type of work. Additional anchoring of large unstable rock masses on the face may be required.
Catch walling rock fall protection is a freestanding gabion wall of sufficient mass to withstand impact of falling rocks. Location of the catch wall and height of the wall is important to ensure the trajectory of the falling rocks will be impacted on or behind the wall.
