Bidirectional steel-plastic grid is a premium geosynthetic reinforced material created through a high-tech process, combining high-strength steel wire ropes or wire bundles with polypropylene (PP) or high-density polyethylene (HDPE). It utilizes ultra-high-strength steel wire as its core load-bearing framework, with an extruded plastic coating providing protection and weld points. These wires are arranged at specific intervals in both the longitudinal and transverse directions and ultrasonically welded to form a robust grid structure. This unique composite structure combines the high strength and modulus of steel with the excellent corrosion resistance of plastic, providing the ultimate reinforcement solution for the most demanding projects.
