25-foot span -- what materials to use
25-foot span -- what materials to use
(OP)
After posting this question with too many details previously, I will try the basics.
I am looking for a material (angle iron, box steel, or similar) to span a 20-foot length without sagging. It will only need to support its own weight + 15% or so. Weight is an issue so lighter is better.
Great site, by the way.

The question is meaningless, any real system that is non-active will sag.
What is the real load?
