Jinhua City New Hangsun Lightning Protection Equipment Co., Ltd is a leading manufacturer and exporter of grounding products, under which the factory Wuyi New Handsun Metalwork Factory was built in 2002.Since the inception, our factory is specialized in the production of copper bonded ground rods and we have been the main supplier for customers at home and abroad. With continuous progress, our company has developed to be a leading exporter with annual export of more than 100 containers of ground rods .
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.
UL ground rod.copper thickness is equal or above 0.254mm.Electricity resistivity is less than 0.059Ωmm2.Tensile strength is equal or above 600N/mm2.Anti-corrosion:put in concentration of 10% nitric acid,soaking for more than 90 hours,no corrosion weight loss is more than 15%.Copper bonding strength: sustain heat above 300 °C up to 1 hour after the quench,the copper layer is not peeled off.
Copper coating plasticity: bend the ground rod to 180 degree,the copper layer doesn’t break or peel
