GI Chemical Earthing uses a hot-dip galvanized iron pipe surrounded by special backfill compounds (like bentonite, graphite, carbon powder, or minerals) to maintain low soil resistance for a long period—even in dry or rocky soil.

It is more effective and long-lasting than traditional charcoal-salt earthing.
Components of GI Chemical Earthing

1. GI Earthing Electrode

   • Pipe diameter: 40 mm / 50 mm / 65 mm / 80 mm

   • Length: 2 m / 3 m

2. Hot-dip galvanized (80–100 microns)

3. Inner GI Strips/Conductors

   • Increase surface contact

   • Enhance current dissipation

4. Backfill Compound (BFC)

   • Mineral-based, carbon-based, or bentonite

   • Non-corrosive, improves soil conductivity

5. Cavity for chemicals inside the pipe

   • Slow-release chemical mixture

   • Maintains resistance over time

6. Copper/GI Terminal Clamp

   • For connecting earth strips or cables
