Unthreaded copperbond earth rod
Furse copperbond earth rods probably offer to the installer, the best and most economical earth rods available.
They 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.
