Source for oval or filleted "80/20" like extrusions

[Reddinr]

So I'm thinking about making my own racks for my truck because the Yakama racks I looked at were an astounding $1600 plus tax/shipping. Does anyone know of a source of extruded aluminum shapes much like 80/20 but not square/rectangular for better air-flow? I'm absolutely certain I can make something that works well and looks good for half that or even less.

I've been "googling" for a while and never found that. Thanks! Related to this, I did find some oval tube at Taco marine. A bit pricey though.

I searched quarter round t slot extrusion. I knew I had seen it before, but got lucky with my search terms.
