The most common Furse earth rods sold are Copperbonded steel core due to cost, strength and corrosion resistance. Solid copper and Stainless Steel rods are also available, providing excellent corrosion resistance but are lower strength and more expensive.
Earth electrode materials
Copper Bond earth rods are made by molecularly bonding 99.9% pure electrolytic copper onto a low carbon steel core. Furse rods are not of the sheathed type. They are highly resistant to corrosion, and because the steel used has a very high tensile strength, they can be driven by power hammers to great depths. The counter-bored couplings are made from high copper content alloy; commercial brass is not used, ensuring excellent corrosion resistance and high strength.
Solid Copper earth rods offer higher corrosion resistance. They are ideally used in applications where soil conditions are very aggressive, such as soils with high salt content.
Stainless Steel rods are used to overcome many of the problems caused by galvanic corrosion, which can occur between dissimilar metals buried nearby. Furse stainless steel earth rods are highly resistant to corrosion.
Diameter of rod
Use the most economical rod that soil conditions allow, make savings by not buying over-dimensioned rods. The diameter of the rod does not lower earth resistance dramatically. If you double the rod diameter, the resistance value will only decrease by 9.5% (which means increasing the rod’s weight and cost by approximately 400%).
