I am building a 3 stage trommel with two seperate reverse helix trommels
and am in need of an item which
was used in this homemade trommel. (see video link below) It is black culvert pipe but
is unique in that it is made with a spiral rib as opposed to most
of it which is ribbed but not spiraled.
Does anyone know what brand name this product is?

I think most aluminum culvert is spiraled. It might not be the direction you want but all you have to do is reverse it's spin.
