Re: Trailer ramps
Okay, if you're going to brake the sheets, I'd start with 20" and do a 2" return on the bottoms.
Then add a few 1,1/2 x 1,1/2, x 3/16 angles underneath, every foot or so, you should be good with .125 material.
You'll have to research the material grade.. At a certain hardness , it won't brake without fracturing.
