GRD Sectional copper bonded earth rods.
GRD copper bonded earth rods meet all the requirements of the world’s most rigorous standards, like UL-467 ,CE and ANSI C-33-8. Q235 low carbon steel core coated with an electrolytic copper layer, which is minimum 99,9% pure with no traces of zinc. The copper layer is bonded to steel core through an electrolytic process that ensures a perfect and even bonding between the steel and the copper. The rod finishing is brilliant , free of imperfections or orange peeling.These sectional earth rods are threaded on both ends to allow rod-to-rod connections with couplings. Such procedure permits up to 100-feet depths to be reached with no damage to the threads or the couplings.
