Crafted from high-tensile low carbon steel, these earth rods are engineered by molecularly bonding 99.9% pure electrolytic copper, meeting the standards of BS 4360 grade 43A. To prevent copper oxidation, each rod is treated with Benzol Triozole derivatives. The threads are precisely formed through a roll threading process, preserving the integrity of the molecular copper bond along the entire thread length. These rods are designed for easy installation, either manually or with a power hammer for deeper penetration.
