I would say a scrapyard. They probably won't have a solid 20' section, but I would assume you're using it for something that doesn't requite it to be one solid piece. If I assumed wrong then discregard my post, but if I'm right then I would say scrapyard a good place to get steel. They sell it cheaper then anywhere around here, and it's not rusty junk, they usually get shit in from distributors/mills to sell..

I've had good luck at Finkel's in Lambertsville near new hope and metal supermarket in Plainfield... and most of them will work out deals if you do pieces or will sometimes match prices
