I set up a hot spray plant in American Samoa, and had to run some test prototypes thru, so I thought 'why not my own anchors'?.

So long as the recommendations are followed (ie; blasted to approved profile, sprayed within the time span indicated by temp/humidity), the lastly overcoated with epoxy paint (synergistic relationship with the hot spray), you can have up to a 25 year life.

Using the aluminum (I think) is superiour to zinc, as the aluminum 'self-heals' scraps better.

best,
Michael
