Maximum Corrosion Protection

Between 1910 and 1955, the most comprehensive investigation into the corrosion of buried bare steel and galvanized pipe was conducted by the National Bureau of Standards.

These data were used to determine the probable life expectancy of helical foundations - see Introduction to Corrosion and Galvanizing of Helical Foundations by Perko 2001 in Magnum Helical Foundation Technical Reference Manual.

Twelve samples were buried in Norfolk, VA and in fine sands in Jacksonville, FL where soils are categorized as moderate corrosivity. Samples exhibited an average corrosion rate of 0.64 oz/sf/yr.

Magnum Hot Dip Galvanized Helical Piles in soils with these ratings would provide:

  • Maximum Corrosion Protection
  • 95% probable life expectancy exceeding 140 years
  • Average life expectancy is 350 years
