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 road ways, the mine, the water and electricity project,
the tourist site, the river course and in the municipal
engineering, 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
characters.
Mesh size: The mesh openings shall be hexagonal and of a nominal
dimension of 80mm x 100mm.
Mesh wire: The nominal wire mesh diameter for the body of the netting shall be
2.7mm in diameter and of a nominal 3.40mm for the edge selvedge
wire. All wire shall be in accordance with BS EN 10218-2:1997. The
tensile strength falls within a range of 350 to 575 N/mm2.
corrosion Wire shall be zinc coated to BS EN10244-2 2001. An
additional extruded u-PVC
Project : coating of nominal 0.5mm radial thickness is applied over the
galvanised wire
jointing: Rock netting shall be provided with lacing wire or stainless steel
“C” rings for site assembly. The lacing wire shall be of a nominal
wire
diameter of 2.2mm (all in accordance with the corrosion protection
specified) for final jointing.
