Earth Rod with plated 99.9% pure copper production process, good conductivity,corrosion resistance and higher tensile strength.

1. The Steel Round Bar copper layer thickness: >=0.254mm

2. Resistivity: <=0.05ohm/mm

3. Tensile strength: >=600N/mm

4. Corrosion resistance: working life more than 30 years, relieve     the maintenance cost of earth rod.

5. The copper layer plasticity: the copper earth rods bent 180°,       copper layer without cracks, without sheddingphenomenon,So     it is better than copper wrap steel.
