These earth rods conform to BS 4360 grade 43A. They are manufactured from drawn high tensile low carbon steel with a deposition of 99.9% pure electrolytic copper. Electrolytic deposition ensures perfect molecular bonding between the two metals. Thickness of copper layer is generally upto 250 microns. The threads are formed by roll threading process which ensure strength and maintain the molecularly bonded copper along the full length of the threads. ERCS11200U
These solid pure copper earth rods are made from drawing high conductivity copper and are ideal for use in extreme soil conditions - where there is high salt or moisture content. These rods are highly resistant to corrosion, thus also ensuring longer life. Threads are formed by roll threading process. Internally
