What Happens When Galvanized Angle Steel Is Used As Copper-clad Grounding Rod?

If galvanized angle steel is used to make 5 8 x 8 copper ground rod, although the corrosion of steel is slowed down, zinc is more active than steel and corrodes faster than steel. Since the galvanized layer is in contact with the soil, it is constantly corroding and changing, with poor stability. In addition, the service life of this bonded rod is short (generally less than 5 years), and the resistance value of the copper bonded resistor needs to be tested every year, which is a lot of work.
