These are made from high tensile low carbon steel compiling with requirement of BS 4360 Grade 43 A. Each rod is molecularly bonded by 99.99% pure, high conductivity copper bonding. Each rod is treated with Benzyl triazole derivatives to prevent oxidation of copper bonding. Threads on rods are formed by roll threading process, giving threads extra strength, eliminating risk of chipping the threads while driving the rods in the ground.
