| Vertical  grounding rod is on the low carbon steel core coverage of 99.9% purity made of  electrolytic copper, strong corrosion resistance.Low carbon steel core after  cold drawing process into established diameter, steel  reinforced material has used the tensile strength of 600 n/mm, thus it can be  with the impact hammer installed in considerable depth.Yong into ground rod  copper plating layer thickness of the various points can reach more than 0.254  mm, ensure the ground rod reached more than 30 years of working life in  underground.Ground rod string using the threaded connection to meet the requirements of the  EN50164-2 "lightning protection components (LPC), the conductor and  grounding requirements."
