The most basic difference between a GI Earthing Rod and a Copper Earthing Rod is the materials they are made of, cost, durability, and resistance to corrosion.
Material & Construction:
GI Earthing Rod consists of material GI (Galvanized Iron) which is galvanized zinc-coated with the process of hot dip galvanizing.
A Copper Earthing Rod can be of either copper or copper-bonded steel.
Corrosion Resistance:
Galvanized earthing rods are very corrosion-resistant, but their lifespan varies with soil conditions.
Copper rods have better corrosion resistance and have a longer lifespan, thus being suitable for highly conductive and corrosive soil conditions.
Cost-Effectiveness:
GI Earthing Rods are cheaper than copper rods, thus suitable for large-scale grounding applications with low costs.
Copper Earthing Rods are more expensive because copper is more expensive.
Hot Dip Galvanized Earthing Rods find applications in industrial plants, commercial complexes, and electrical substations.
Copper Earthing Rods are suitable for high-end industrial use and regions with severe soil conditions.
For efficient and cost-effective grounding solutions, Parco Engineers suggests galvanized earthing rods for efficiency and safety in various applications.
