Copperbond Earth Rods

Wallis Copperbond Earth Rods offer installers the most economical method of achieving a low earth resistance.

Each Copperbond Earth Rod has high tensile strength, 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 the rod ideal for deep driving whilst also provides lasting resistance to corrosion.

The threads 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 and 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.
