GRD copper bonded ground rods meet all the requirements of the world's most rigorous standard such as UL-467, ANSI C-33-8, CE B-S10030250. Carbon steel core coated with an electrolytic copper layer, which is minimum 99.9% pure with no trace of zinc. The copper layer is bonded to steel core through an electrolytic process, which is the most advanced automatic continuous plating method. It ensures a perfect and even bonding between the copper and steel. The rod finishing is brilliant, free of imperfections or peelings.

Technique Parameters:
1. UL ground rod. Copper thickness is equal or above 0.254mm.
2. Electricity resistivity is less than 0.059Ω Mm2.
3. Tensile strength is equal or above 600N/mm2.
4. Copper coating plasticity: Bend the ground rod to 180 degree, the copper layer doesn't break or peel.
5. The usage life can be at least 40 years.
