Gi Earthing Plates

A GI (Galvanized Iron) Earthing Plate is a square or rectangular metal plate coated with a protective layer of zinc to provide a reliable, low-resistance path for dissipating electrical fault currents safely into the ground.Key Specifications and Features Standard Size: The most common size is 600mm x 600mm (2ft x 2ft). Thickness: Typically ranges from 3mm to 12mm. According to Indian Standard IS 3043, a GI plate should not be less than 6.35mm thick. Material: Made from high-quality Galvanized Iron (GI) or mild steel with a zinc coating. Corrosion Resistance: The zinc coating acts as a sacrificial anode, protecting the underlying iron from rust and oxidation even in harsh soil conditions. Lifespan: Generally lasts 10 to 30 years, though this varies based on soil acidity and maintenance. Comparison: GI vs. Copper Earthing Plates Feature GI Earthing PlateCopper Earthing Plate Conductivity Moderate (effective for general needs) High (superior electrode) Cost Economical (preferred for residential/small commercial) Higher (often 10x more than GI) Lifespan Long (approx. 10–30 years) Very Long (lasts 8–10% longer than GI) Corrosion High resistance due to zinc coating Naturally immune to most corrosion Application Household, industrial, and budget projects Sensitive sites (data centres, hospitals)
