BCI 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 BCI 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 exceptionally 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.
