What is Steelgrid HR? Steelgrid HR is a high‑stiffness composite steel geonet for active rockfall protection systems. High‑strength steel ropes are longitudinally woven into double‑twisted hexagonal mesh and integrally fabricated in factory. The steel ropes remain straight within the mesh to achieve low deformation, high tensile strength and high punching resistance.
Models are classified by steel rope spacing: HR30, HR50, HR100.
Main applications: rockfall containment and superficial rock mass stabilization for rocky slopes along highways and railways, as well as mine slopes. As a rigid drapery mesh, it is applied in high‑hazard rockfall zones where ordinary hexagonal mesh lacks sufficient strength. ®
