1. General

1.1 Guyed tower anchor shaft corrosion is recognized as a problem by the Telecommunications Industry Association / Electronic Industries Association (ANSI/TIA/EIA-222-F) and the Canadian Standards Association (CAN/CSA-S37-M86). The specifications herein are intended to compliment applicable industry standards.

1.2 Corrosion on guy anchors varies significantly from site to site (and even from anchor to anchor at the same site) based on many interrelated factors. Corrosion control measures beyond hot-dip galvanizing are virtually always appropriate as a precaution, and depending on site specific conditions, may be essential.

1.3 Corrosion is an electrochemical process by which refined metals return to a native state. Certain conditions must exist for a corrosion cell to function. There must be metal or metals with at least two energy levels, an electrolyte (such as soil, water, or concrete), and a conductor. The metal that gives up energy (anode) corrodes, while the metal receiving energy (cathode) maintains its form. See ANSI/TIA/EIA-222-F, Annex J for discussion.
