GI Earthing Electrode provide a low-impedance ground in locations of high soil resistivity. Together with Reslow Grounding Minerals, the system dissipates lightning energy and other dangerous electrical fault currents, even in sandy or rocky soil conditions.

GI earthing electrodes are popular due to its low cost, easy to install and readily availability with stockists. Galvanised Iron has good stability in earth comparing to many other metals and hence more popular. The earth values are also good and stable with time. GI electrodes are common for 3 meters but 2 meters and 1.5 meters also in use for areas where installation is difficult due to rocky areas or other reasons like high water level.
