Why not use chain link fence top rail instead? It comes in several
different sizes, is cheap, galvanized, comes in 21' lengths (1 1/2 pieces
do the job) and they are swaged on one end.
Check them out at Home Depot. If you think you need something different
than what they carry look in the yellow pages for a chain link fence dealer.
