Overview
Hot-dip galvanised iron (GI) electrodes are a robust, budget-friendly option for general building and industrial earthing where soil conditions are not aggressively corrosive. A zinc coating of at least 80 microns sacrificially protects the steel beneath, extending service life in normal soils. Available as pipes or strips, GI electrodes are easy to source, install and bond, making them a practical default for distribution boards, lightning earth pits and equipotential bonding grids on a controlled budget.
Frequently asked questions
What is a GI earthing electrode?
A GI (galvanised iron) earthing electrode is a hot-dip galvanised steel pipe or strip with a zinc coating of at least 80 microns that sacrificially protects the steel, making it a robust, budget-friendly option for general earthing.
When should I use GI instead of copper?
GI electrodes suit general building and industrial earthing in non-aggressive soils on a controlled budget. For low-resistivity or corrosive soils and sensitive loads, copper or copper bonded electrodes perform better.
