SNS Flexible passive protection system for building facilities next to the buffer zone of the high ranges, the rock fall, flying rocks, avalanches, landslides blocked the building facilities, building facilities to avoid the disaster of the destruction. The main products are the following types: P1 type: single diagonal block (h <100m). I-beam columns, anchor systems, support rope, reduce red rings, wire rope. P2 type: double intercept (h <100m). P3 type: channel-type block (the road on both sides, one side is steep, one side is the abyss.)
