Details

Copper covered steel ground rod

The copper covered steel ground rod is made of super-quality soft steel with good softness and carbon content of 0.10%-0.30%, and high-conducting electrolytic copper is uniformly covered on the surface of  the round steel by adopting a special technology, and the thickness is within the range of 0.25-0.5mm. The technology can effectively slow the speed of underground oxidation of the ground rod; and the ground rod adopts a roller thread groove to machine threads, thereby keeping the tight connection between steel and copper, ensuring high strength and having good electric grounding performance.
