Auroguard supplies rock fall protection systems including double-twist hexagonal wire mesh for drape/containment netting, ring-net barrier systems, and anchored wire-rope barrier fences. Drape netting is installed over rock slopes to guide debris to a catchment trench at the road toe. Barrier systems are anchored to the slope above the hazard zone and absorb the kinetic energy of falling rocks using brake elements. Applications include highway and railway cut slope protection in Jharkhand, Odisha and Bihar, quarry boundary protection, infrastructure protection in hilly terrain, and coastal cliff protection. All wire mesh is galvanised to IS 4759 / ASTM A123 with optional PVC coating for high-humidity coastal environments.
