The passive SNS shielding system is also called stone blocking mesh and rockfall barrier, made by flexible steel wire rope netting installed in the slopes to stop the falling rocks. It can also be installed in the mud-rock flow area to form the flexible fencing dam to stop the huge solid pellets in the flow. Rockfall barriers are used to catch rockfall and debris from falling onto roads, railways and reduce the risk of possible injury or loss of property or life. These barrier systems work as a passive system by absorbing the impact energy of the rock or debris before they reach the protected area. The systems are composed of galvanized panels (ring net panels, cable panels with clips or HEA knots), galvanized steel posts, state-of-the-art friction brakes, galvanized steel cables, cable and steel rod anchors, wire mesh, and accessories.
Our rockfall barriers have been successfully tested under the most demanding conditions to absorb rock energy impacts of 500 to 5000 kJ.
Barrier Options:
Powder Coating
Choice of cable panel or ring net panel (excluding 500 kJ)
