NATIONAL's Earth Rods are made from high tensile-low carbon steel compling with requirements of BS 4360 Grade 43 A. Each rod is molecularly bonded by 99.99% pure, high conductivity copper bondings, each rod is treated with Benzol-triozole derivatives. 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. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Solid Copper
Earth Rods | ||||||||||||||||
NATIONAL's Solid copper earth rods are made in two types. Externally threaded and internally threaded. Solid Copper earth rods are used where the factor of corrosion is very high and expectionally long life is required. Hence these rods are manufactured from pure and high conductivity hard drawn copper to BS 2874-C 101. These rods are also available with tin plating in order to reduce the risk of oxidation and increasing shelf life. | ||||||||||||||||
