Copper-clad steel earth rods are widely used in grounding and earthing systems to provide a safe path for electrical currents to dissipate into the ground.

**Key Features:**
1. **Material Composition**
- **Core**: High-strength low-carbon steel for mechanical durability.
- **Cladding**: Electrically conductive copper layer (typically 0.25mm–0.5mm thick) bonded to the steel core.

2. **Corrosion Resistance**
- The copper layer protects against corrosion while maintaining conductivity.
- Suitable for harsh environments (e.g., acidic soils, high moisture).

3. **High Conductivity & Strength**
- Combines the electrical properties of copper with the tensile strength of steel.
- Can be driven deep into the ground without bending or breaking.
