While wandering around Menards last night I walked past the black iron pipe in the plumbing section. I got to wondering if you can use it for fencing. My idea would be to run it 5 bars across and fasten it to wood fence post every 10 feet or so. Anybody know if you can use it for fencing? Wasn't sure how it would hold up to the weather. I tried Google(ing) the idea and came up with no answers. Thanks for your help.
