Q: I will be using some steel in a below-grade application. If I hot-dip galvanize the steel, how long will it last?
A: As is the case with any corrosion protection system, the two most common questions about hot-dip galvanizing are in reference to the life of the coating and the costs associated with using it. Fortunately, the American Galvanizers Association has developed a tool that allows specifiers to quickly reference a visual guide approximating the corrosion protection performance of hot-dip galvanized steel in soil conditions known as the Service Life of Galvanized Steel Articles in Soil Applications chart. The visual aid estimates the amount of corrosion protection provided by a hot-dip galvanized coating in soil applications given the initial thickness of the coating and varying soil conditions. |
