Also Carolina Steel, but my accounts are through Benco. I have been told Carolina is more friendly toward selling drops or cut lenght products. I have always bought 20 ft stock. Pending on what your looking for some board members may be able to supply what you need. I've also tacked own a few odd items to get something someone needs. Benco does not stock Chromoly tubing. If its cage material they only carry standard structual tubing.
I may have most of this if you still need. Another good source for this short length randoms is Metal Express in Charlotte, N.C. They can ship to you since that is a little ways away. Also, Schwartz Steel in Gastonia. Not too terribly far away. Good luck!
