Copperized Ground Rods using special electroforming technology, plating 99.9% pure copper uniformly to the high quality low carbon steel core, through cold-drawn process, to make tensile strength stronger, and maintaining toughness, with thick copper, well agglutination and so on. Have constant low resistance and good plasticity, both with the same electrical conductivity of copper and also have the steel characteristics. Conventional copper layer thickness is 0.254mm, 0.33mm, 0.5mm, 1.0mm.
