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 LISTED COPPER BONDEDEARTHING ROD99.9% pure electrolytic copper molecularly bonds onto low carbon high tensile steel cores.GRD ground rods provide the marking of UL logo,length,diameter,plating thickness etc.UL listing requires minimum copper plating thickness of 10 mil.Model No.DiameterCopper ThicknessLength(ft) Thread Size Packing 126 1/2'' (12.7mm)10mil (0.254mm)6/101281/2''(12.7mm)10mil (0.254mm)8/105845/8’’ (14.2mm)10mil (0.254mm)4/105855/8’’ (14.2mm)10mil (0.254mm)5/105865/8’’ (14.2mm)10mil (0.254mm)6/105885/8’’ (14.2mm)10mil (0.254mm)8/1058105/8’’ (14.2mm)10mil (0.254mm)105/810584s5/8’’ (14.2mm)10mil (0.254mm)45/810585s5/8’’ (14.2mm)10mil (0.254mm)55/810586s5/8’’ (14.2mm)10mil (0.254mm)65/8105810s5/8’’ (14.2mm)10mil (0.254mm)105/8103453/4’’(17.2mm)10mil (0.254mm)4/53463/4’’(17.2mm)10mil (0.254mm)5/53483/4’’(17.2mm)10mil (0.254mm)6/534103/4’’(17.2mm)10mil (0.254mm)10/5345s3/4’’(17.2mm)10mil (0.254mm)53/45346s3/4’’(17.2mm)10mil (0.254mm)63/45348s3/4’’(17.2mm)10mil (0.254mm)83/453410s3/4’’(17.2mm)10mil (0.254mm)103/45
