A. N. Wallis manufacture and supply the complete range of Copperbond Earth Rods, offering installers the most economical method of achieving a low earth resistance.

Each copperbond earth rod has a high tensile strength and low carbon steel core. 99.95% pure copper is applied electrolytically and forms a metallurgical bond between the steel core and the copper. This combination makes each earth rod ideal for deep driving whilst also providing lasting resistance to corrosion.

The threads on each copperbond earth rod are formed by a cold rolling process which ensures strength and maintains the molecularly bonded copper covering along the full length of the threads. Cold-rolled threads are stronger than cut threads.

The standard copper thickness is 0.25mm. Greater copper thicknesses are also available. Please contact our sales office for further information.

We offer a wide range of different sized Copperbond Earth Rods along with compatible threaded couplers and threaded driving heads, we also offer a quick quoting service. If you have any questions regarding any of our products, or if you require a price list please feel free to contact us.
