The zinc-clad steel grounding rod ingeniously combines the high mechanical strength of steel with the ultra-low potential characteristics of zinc, integrating both "physical grounding" and "cathodic protection" into a single unit.
The zinc-clad steel grounding rod features a high-quality low-carbon steel core continuously extruded with a high-purity zinc sheath (Zn≥99.995%). It ingeniously combines the high mechanical strength of steel with the ultra-low potential characteristics of zinc, integrating both "physical grounding" and "cathodic protection" into a single unit. Utilizing the sacrificial anode action of zinc, it not only dissipates fault currents efficiently but also actively protects adjacent steel structures from electrochemical corrosion. Offering significantly enhanced corrosion resistance compared to conventional materials, it is particularly suitable for petrochemical storage tanks, oil pipelines, and highly corrosive soil environments, representing an optimal solution for lightning protection grounding and cathodic protection systems.
