SteelGrid is a woven geo-composite made by assembling together steel wire and ropes during the production of hexagonal woven double twist wire mesh. SteelGrid mesh rolls have a standard length of 25 m or 50 m and a width of 3 m.

SteelGrid MO - (Mono Oriented) - Steel ropes, 8 mm in diameter, are used in place of the conventional selvedge wire and also inserted longitudinally in the woven mesh at a distance of 1,5m and is particularly applicable to simple revetment type applications.

SteelGrid BO - (Bi Oriented) - Steel ropes, 8 mm in diameter are used in place of the conventional selvedge wire and also inserted longitudinally in the woven mesh at a distance of 1,5m (except for STEELGRID BO 300 where steel ropes are inserted at 3,0 m spacing). Steel ropes are also inserted in the transverse direction through the mesh securing the edge ropes with clips during manufacture at a distance of 1,5m, 2,0m and 3,0m, (STEELGRID BO 150, STEELGRID BO 200, STEELGRID BO 300), respectively.

The SteelGrid geo-composite is particularly suitable for rockfall protection as a drapery system for surface or soil veneer slope stability. It has the big advantage of connecting the longitudinal ropes to the top anchor rope and the weaving of the ropes inside the steel mesh increases the lining’s strength, resulting in a more effective anchoring ability.

The steel wire used in the manufacture of the double twisted wire mesh is heavily galvanised with Galfan, a 95%Zn-5%Al-MM (mischmetal) alloy. The double twist prevents unravelling of the mesh should any accidental wire rupture occur.
