Grounding Products and SystemsTechnical SectionERITECH ® Copper Bonded and Hot Dipped Galvanized Ground Rods1.0 Copper Clad Ground RodsERITECH copper clad steel ground rods are manufactured indiameters of 1/2", 5/8", 3/4" and 1”. They are available in pointed orsectional (threaded) finishes as well as different thickness of plating.1.1 Steel1035 Steel – cold drawn to ASTM A1080 and AISI C1017standards, except for 3/4”, which uses 1018 steel. Tensilestrengths are as follows:Rod Diameter Average Range3/8” 86,500 psi 75-95,000 psi1/2” 86,500 psi 75-95,000 psi5/8” MIN. 90,000 psi 90,000 +3/4” MIN. 90,000 psi 90,000 +1” MIN. 90,000 psi 90,000 +1.2 Copper PlatingThe copper is applied electrolytically, forming a metallurgicalbond between the steel core and the copper. The copper istype DHP alloy #122CDA and is rated at 99.95% copper. Theend result is a high quality bond between copper, nickel andsteel. ERITECH plates to thickness of 0.005", 0.010", and0.013". For rods plated over 0.010" there is a tolerance of+.002" and -.00".1.3 Finishing1.3.1 Diameter: measurements based on finished platedproduct.Rod SizeAverage Diameter1/2” .500”5/8” .561”3/4” .677”1” .910”1.3.2 Plating Thickness: the copper plating can becontrolled to the following thickness levels and iscontinuous over the rod with the exception of thepointed and chamfered ends.Mil ThicknessAverage Diameter5 mil .0050”10 mil .010”13 mil .013”1.3.3 Machining:1.4 Marking of RodsStandard pointed rods are conical pointed to 60degrees on one end and are cut square andchamfered at the other end. Sectional threaded rodsare roll-threaded to provide American Standardcourse thread requirements with a class 2 fit. Oneend of a sectional rod is threaded with a “flat” pointand the other end is a threaded chamfered end.Standard lengths are 6, 8, and 10 feet with atolerance of +5/8" and –0".Each rod is imprinted within 12" of the top of the rod with:part number indicating rod diameter and length, manufacturerlogo and UL mark (when listed).1.5 PackagingGround rods shall be packaged in bundles with reinforcedtape or metal banding and then bound securely in steelstrapped master bundle.Rod Size Bundle Quantity Master Bundle Quantity1/2” 10 1005/8” 10 1003/4” 5 501” 1 251.6 ReferencesUnderwriters Laboratories UL 467National Electrical Manufacturers Association NEMA 8CC-5/GR-1American National Standards Institute ANSI C33-8ASTM A1080; AISI C1017 for steelNaval Facility Engineering Command NAVFACENGCOM12.1Military Handbook MILHANDBOOK419RUS – 13 mil.
