I am not looking for a great deal. I just need to get it for whatever
is the market price.

I need a structural rectangular tube, about 4 feet of it, dimensions
8x10 inches in cross section by 0.625" to 3/4" thick.

Does anyone know any steel supplies who procure that sort of stuff.

Thanks

The key word is "fabricator".
