GTI® Hi-tensile Rockfall Protection Netting
GTI high tensile rock fall protection nettings protect against rock fall by trapping dislocated rocks at surface of the rocky slope. The loose rocks can slide anchors in a controlled way our time removal of sliding rock mass can be achieve in a systematic way. The nettings have a very high energy absorption capacity and can hold back very large boulders. These are two types of GTI high tensile rock fall protection nettings.
1.Cross-linked Rhomboidal / Square Mesh Steel Wire Rope Panels (Brand Name: ‘RockNet’)
2.Double Twisted Hexagonal Mesh Wire Rope Tied Netting (Brand Name: ‘StrongNet’)
GTI® ROCKNET
These are designed and manufactured to reach formidable tensile strengths up to 300kN/M at very low strain. A single continuous length of steel wire rope of 8-10 mm diameter and 1770 N/mm2 grade (tensile strength) is wound around a frame a netting panel of rhomboidal shaped openings. The openings are of typical size 300 mm by 300 mm. the rectangular netting panel is typically 4-6 m long on each side.
GTI Cross Linked Rhomboidal/ square Mesh steel wire rope panels are typically installed with small aperture secondary DT meshes to enable holding back of small sized debris.

GTI® STRONGNET
These are manufactured by combing Steel Wire Ropes of 8 mm-10mm diameter with Mechanically woven Double Twisted Hexagonal with opening Steel Wire netting (IS 16014) to create a product with high tensile strength at low strain and high punch strength with low deformation. This is achieved by tying the Wire Ropes longitudinally to the edge wires of the Double Twisted mesh lacing wire. Steel Wire Ropes are also tied longitudinally to the mesh wires at intervals of 0.3 m to 1.5 m from the wire to which an adjacent Steel Wire Rope is tied.
The hexagonal IS 16014 mesh type and rope spacing is designed to provide various strengths reaching upto 200kN/m. StrongNet has excellent fall during installation due to the vertical wire ropes and provides excellent function as drapery mesh system. The double twist of the hexagonal mesh prevents unravelling of the netting if a wire gets cut due to any reason.
Strong Net is designed to work efficiently with anchorage system. The longitudinal wire ropes provide the strength to prevent shrinkage of the mesh under self-weight during installation and under weight of debris collected behind the mesh.
