[TowerTalk] Concrete anchors

[Richard Thorne]

I just finished re-furbishing a rotating tower.  Several of the parts 
needed to be galvanized.  We don't have a local galvanizing company here 
in Amarillo.

What we do have is a local metal fabricator who  sends a truck out 
weekly to a galvanizing company.  Maybe you can find a fabricator 
locally that has a relationship with a galvanizing company.
