Unthreaded copper bond earth rods

Threaded copper bond earth rods

First copper bond 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. First 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. This again ensures excellent corrosion resistance and high strength.
