I may end up doing that but using aluminum.

The easiest solution is to use steel channel of commensurate strength and just paint the hell out of it.Vance

Before I make a final decision, I have found a suitable i-beam for my application that is very reasonably priced.  The problem is that it is American Standard "S" shape which means the flanges taper toward the web.  Since I have to bolt it through the tapered flange to another member the nut will not sit flat against the flange.  Is this a problem and is there a fix to it?  beveled washer necessary?
