Copper covered steel grounding rod for the most economic means to reduce grounding resistance, grounding rod is composed of high strength low carbon steel and 99.95% pure copper, copper and steel for molecular connection, can have good corrosion resistance and direct deep buried, thread extrusion by rolling machine, can ensure its strength, and keep the copper layer always covered in the thread. The thread extruded by the thread roller is much stronger than that opened by the lathe. Standard copper layer thickness is 0.254mm, larger copper layer thickness is optional.

Material: Pure copper covering the steel core.
