Thanx chris. I did a little research on sizing the Angles and finding out what kind of point load or impact load these can take, and by my estimates it is not much at all. As far as bracing.. I think a C-channel is a better idea than an angel or a piece of box tubing, But Im more concerned about weight, So. My conclusion is as follows.. I think I'll be using my Ladders as Sand ladders and I wont even attempt using them for bridging ladders, unless I have a brick or something to put in the middle of the span. I will hopefully use a Plasma cutter, or torch to cut them, if I can't get access to either, then I'll try an Air Whiz wheel, or sawzall, ugh. In light of this new info from Chris, I'll be Definitely trimming them down to 4' by 1' just so they're easier to use, mount, store and of course finish. Maybe ths guy can cut them for me so I can save some money of shipping. Hmmmmm.
Now I understand why the Land Rover bridging ladders are aluminum, and $429. Aluminum has a strength to weight ratio 7 times better than steel. So the rover ones weigh nothing but can still support a heavy truck over a 5 foot gap. Interesting..
Screw Im sticking with steel.
