♦ Copper Bonded Earth Rods
- Earth rods are made by moleculary bonding process 99.9% purity electrolytic copper onto a high tensile low carbon steel cores to ensure a perfect and even bonding between the steel and copper in accor-dance referring to national and international standards such as UL467 and BS7430.The copper layer whose minimum thickness is 254 microns.The steel core is a bar drown.standard size diameter being the most popular used 1/2",5/8",3/4".
- Our Earth rods with high in protection against natural corrosion and electrochemical reaction when rooted deeply in ground.Earth rods and grind wirings are welded by leiying’s exothermic welding powder so that the ground system are protected by the copper wholl and free of maintenance.
- The rod length range from 4"up to 10".Earth rods are also available in the sectional type with the same length and diameters.These sectional rods are threaded on both ends to allow rod-to-rod connection by use the coupling.

♦ MAIN CHARACTER:
1) Thickness of the copper layer is more than 0.1 ~ 0.25mm.
2) Our ground rods can be bended through a 30 or 90 or 135 degrees angle,and the rods will be no evidence of cracking or splitting of the steet or the copper cladding.
3) The advantages are good tensile strength more than 580N/mm².
4) Good in anticorrosion that usage-life is more that 50 years or more,constant low resistance and good plasticity which had the characteristics of copper as steel.
♦ Note
1) Diameters with Φ12.7mm, Φ14.2mm, Φ17.2mm,we can supply you earth rod with threads as UNC-2A and metric standard.Pls let us know your request before produce.
2) We can supply you earth rods with much more thickness of copper layer such as 25 microns,50microns,100microns,127microns,254microns and 330 microns etc.
3) Also,we can supply you earth rod with two ends thread ,un-thread but with one end point,one end thread and the other end point.
4) Length of earth rod as your request.
