    You will get arround 50% more deflection (bending) if you use angle as like ^ or V.

    If you happen to have some uneqal leg angle (like 2x3x1/4) it is stronder with the long side in the same direction as the load.

    Thanks for all your input on this everyone. This website is extremely helpful from very knowledgeable folks!

    I definitely agree that channel would be better, but I had a bunch of angle around so thought that would be better.

    I went with option #1 and seems to be very stiff.

    way to use angle-iron for bearing lateral load

    two opposed members, are required for load-carying applications.
    Example , say a weld-table top.

    If you have angle and want to make use of it, #1 is the best orientation. It will also be easier to attach stuff to. Channel or box could be better in this application BUT I think once the boards are tied into the angles it will stiffen them up just fine. Nice graphics, BTW!

    Key reason that commercially built trailiers use channel!

    I agree with Vicegrip.

    Channel would be a much better choice in this application.

    Maybe it was originally called dangle iron?

    Mac's right per the question.
    The question is based on a miss-applicaton.

    Actually angle-iron is not meant to be load-bearing across it's section.
    It is made to be used in "tension" situations, providing two surfaces
    square to each other at the ends for attachment to the
    (object requiring latteral reinforcing).

    Channel is the preferred product you may want to considering,
    based on structural applicication.
    Yes angle is used this way in many applications including bed-frames, but
    if you really desire / need good support, channel is a better choice.

    #1. MAC702 said all that is necessary.

    Attached is another picture, showing the layout I was planning. Thanks.

    Very nice graphic illustration, by the way.

    #1.

    Take a 20' piece of angle and balance it, holding it in the middle. #1 will flex the ends down much less than the others, and be easier to attach at the same time.
