KALISTER copper bonded grounding rods are made by molecularly bonding 99.98 pure Electrolytic Copper on to a low Carbon steel core to a thickness up to 0.35 mm. 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. Couplings threads are formed by rolling process to ensure thread strength and to maintain durability. The universally used thread rolling process raises the surfaces of the Rod. Thereby achieve the thread diameter greater that the Rod diameter. All the threads are Unified National Coarse. The counter–bored couplings are made from high copper content alloy. Connections to copper bonded rods can be by Mechanical clamps, compression or Exothermic welding system.
Earth rods are made in accordance to BS EN 50164-2, BS 7430 and Fittings to BS EN 50164-1
