Manufactured from high tensile low carbon steel by molecularly bonding 99.9% pure electrolytic copper, these earth rods conform to BS 4360 grade 43A.  Each rod is treated with Benzol  triozole derivatives to prevent oxidation of copper bonding.  The threads are formed by roll threading process which ensure strength and maintain the molecularly bonded copper along the full length of the threads. The rods can be deep driven manually or by using power hammer.
