I was very disappointed with JD Recyclers the 1st time I went there. The selection just isn't there. They have lots of 'scrap' but specifics are hard to come by. For all practical purposes you can say they have no sheet metal. Yeah, a few high dollar stainless steel sheets and maybe some misc pieces of 'plate'.
If you are a metal worker and want some steel bar to chuck in your lathe to make something then, yeah, go look there. Want that odd piece of angle iron or some bigger 'chunks' then again, they might have it. Last time I went it was $.50/pound for buying steel and $1.50/pound if you needed aluminum.
They do have some new angle iron and steel tubing in 20' lengths hidden away in a container that goes for a better price than Dillon though. You have to specifically ask for something though and expect to buy at least 10' of it. Surprisingly they had 2x2, 1/4" wall tube that I wanted.
