The thickness of copper bonding is an important factor in establishing the durability and efficiency of copper bonded earthing rods. For the best performance, industry standards suggest a minimum of a 250-micron (0.25 mm) copper coating over the steel core. This is a thickness that has an excellent corrosion-resistant layer yet good electrical conductivity. If the copper layer is not too thick, it can wear away prematurely from soil conditions, moisture, or mechanical stress during installation, diminishing the life and reliability of the grounding system.
A 250-micron or larger copper coating provides the rod with the ability to tolerate aggressive soil environments, withstand chemical corrosion, and provide reliable conductivity for decades. The steel core under the copper provides mechanical strength, enabling the rod to be hammered far into different soils without bending or fraying. This union of strength and conductivity makes copper bonded rods significantly more cost-efficient and long-lasting than pure copper or galvanized steel options.
Pioneer Powers International produces high-quality copper bonded earthing rods with industry standard copper thickness, providing long life performance, low maintenance, and high safety for domestic, commercial, industrial, and renewable energy applications.
