UL and CSA approved ground rod. CE approved products

 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 4-dimensional continuous plating method,which ensures a perfect and even bonding between the copper and steel. The rod finishing is brilliant,free of imperfections or peelings.

Technique Parameters:

1.For UL and CE standard ground rod.copper thickness equal or above 0.254mm.

2.Electricity resistivity equal or below 0.059Ωmm2.

3.Tensile strength equal or above 600N/mm2.

4.Anti-corrosion:put in concentration of 10% nitric acid,soaking for more than 90 hours,no corrosion weight loss equal or above 15%.

5.Copper bonding strength: sustain heat above 300 °C up to 1 hour after the quench,the copper layer is not peeled off.

6.Copper coating plasticity: bend the ground rod to 180 degree,the copper layer doesn’t break or peel.
