Lyn,  you neglected to indicate the FAILURE  MODE.

Did the SHAFT corrode?  If so,  how would a concrete
anchor be less susceptible?

Or did the anchor merely pull out?  If so, then perhaps
the soil was too loose or the anchor had too small a
plate or too short a shaft.  Proper size selection IS
important!
