Not so long ago, not many people thought about materials to make ground electrodes. The ordinary, "black" steel was mainly used. The result was the same - grounding had been working for 10 years maximum after what, corrosion, eating the major part of the grounding device made inefficient.

Now, after the introduction of such regulatory documents as GOST R 50571.5.54-2013 and GOST R EIC 62561.2-2014, which prescribe to use the materials providing the required corrosion strength, not many people will risk and make grounding the same old way. And the economy is only seeming, after many years of the object use, a full reconstruction of the grounding device will be required, the expenditures on which will exceed the cost of corrostion-resistance grounding.

The market range of corrosion-resistant materials for ground electrodes is not wide, but the choice is not easy either. How to understand what material to use:copper, copper-bonded steel, stainless steel or galvanyzed steel? W will answer this question and will help you to choose a correct ground electrode fitting certain conditions.

From the article "Different types of ground electrodes in different types of grounds" you can learn the peculiarities of ground electrodes, made of different metals and what factors influence their service life.
