Why Is It Important To Pay Attention To The Tensile Strength Of Copper-clad Grounding Rods?

The commonly available copper bonded earthing grounding steel core is typically made of low-carbon, high-strength steel, processed through electroplating or cold rolling and hot drawing. After processing, its tensile strength often reaches over 600 N/mm². This strength level meets the mechanical performance requirements of most grounding projects. The outer, uniformly covered pure copper layer is at least 0.254 mm thick to ensure the corrosion resistance and conductivity of copper bonded steel grounding.

During the material selection and acceptance phase, the accompanying documentation and test reports for copper bonded steel ground rod grounding should be reviewed to confirm that the steel core material, tensile strength value, and copper layer thickness of copper bonded steel rod grounding conform to the design specifications. If the tensile strength is lower than the standard, it is recommended to replace or repurchase qualified products to avoid breakage or corrosion damage during construction.
