I got my patent, 7,707,794. Now I'm trying to write up a press release and have a glitch. I know that channel is strong two ways while pipe is strong all ways. Somewhere there's a formula or chart that shows equal weight channel is so many times stronger than pipe channel's strong way.

Come on engineers, give this never-got-high-school-diploma dude a hand.

What I'm wanting to compare is 1 1/4 schedule forty pipe and 2 X 4 inch 14 gauge C channel or purlin.
