Copper-Bonded Ground Rod Built from high tensile steel, copper-bonded ground rods can be hammered to the ground. Also, the ground rods are made of a nickel-plated technology, resulting in high-adhesive-copper bonding, which is not disunited when planted to the ground. The copper has a minimum thickness of 250 microns, a lifespan of around 40 years (pH 6-8), and extended capability. The copper thickness can also be increased to 1,000 microns for an even longer lifespan. There are two series of copper-boned grounds, which are the UL Series and TIS Series. UL Series Passes and UL listed, UL Series ground rods also complied with IEC 62561-2 and TIS 3024-2:2020. TIS Series TIS Series passes the TIS standard and abides by TIS 3024-2, which complies with IEC 62561-2. Solid Copper Ground Rod solid copper ground rod is built from pure electrolyte copper, which has high resistance in various grounding environments, such as pH>8 or saline areas (e.g., seashore). It also passes IEC 62561-2 standard. Caution: Do not directly hammer the ground rod into the ground; please dig a borehole before ground rod installation. Otherwise, the ground rod will be chipped and damaged. Stainless Steel Ground Rod Stainless steel ground rod is IEC 62561-2 certificate. It is built from 316L stainless, which has high chemical resistance in all types of grounds, especially pH<6. Additionally, 316L stainless is a low carbon type, and it has a stronger weld than 316 stainless when proceeding exothermic welding. Caution: stainless steel ground rod under IEC 62561-2 standard must have molybdenum composition >2% for rust prevention. Consequently, an ordinary 304 stainless cannot be used as a ground rod abided by the IEC standard.
