Hi all; about to start building a trailer. The trailer plans I
bought from trailerplans.com call for 2"x3"x1/4" angle iron. I
want to use steel tube instead. Can anybody give me an idea of what
size steel tube would have the same strength? Is there somewhere
this can be looked up?


2" x 3" x 1/8" rectangular tube should be as strong as 2" x 3" x 1/4"
angle and have about the same weight per foot.
