Socome copper bonded 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,n to a low carbon steel core.
Confusion often arises between thread and shank diameters for threaded rods. The thread rolling process, used by quality rod manufacturers, raises the surface of the rod so that thread diameter (B) is greater than shank diameter (A) (see drawing).Copper thickness standard 254 microns.(others plating copper thickness as your requested)Earth rods to BS EN 50164-2, Bs7430 and UL467; Fittings to BS EN 50164-1.
