Magnesium Anode Protection
The outside of the TEII steel systems are painted with suitable paint for the application. To minimize corrosion from acid soil, sacrificial magnesium anodes are buried in the ground approximately ten feet from the metal plant. It shall be attached to the system with a copper wire. During the construction, proper installation of the anodes is critical. Allowing enough slack in the copper wire so that it will not break during backfilling is important.
Cathodic Protection with magnesium anode packages are supplied with all below ground installations of all prefabricated steel systems.
