Hi Yuri

I lived in my last house for slightly over 20 years.

Although a high percentage of the welded wire fabric decomposed over
that time, leaving iron in the soil, evidenced by all of my hydrangeas
turning bright blue, the areas of aluminum fencing never did
deteriorate.

In fact, the fencing I will be using is the same fencing that
surrounded my property for those 20 years, with the lower ends buried
over a foot into the ground. Not the actual fence, but a partial roll
I had left over after constructing the fence. That had been in
storage all this time.

If I could find a company that makes this same small weave aluminum
fencing I would have them do my whole yard at my new house. But I
have not found it available anywhere. Perhaps as you pointed out, it
don't hold up under certain conditions.

My aunt lived in Florida for awhile, she had the same type awnings
installed, by the same manufacturer even, that she had installed some
25 years earlier in St. Loo, they didn't hold up but only 4 years and
were full of holes. Assumably from the salt air.
