Utility trailer opinions
I'd like to know some opinions on using rectangle tubing for a 5x10 utility trailer frame. This would be for the outer frame only, and I'd probably going to use 2x2x0.25 angle for the cross beams, and diamond plate for the floor. I've done all my strength of material and weight calculations, so its down to is it worth the exta cost for tubing vs angle? Strength is close enough, and weight is within 50lbs. If I choose tubing, I already plan on welding the ends shut to keep water out. So no worries on rust.
Thoughts?
Thanks

Now that I've had a little more time to think about what I'm after, here a more specific question to my dilema. Is a little more strength and rigidity of a tube frame worth the extra cost?

I do as well, but being a small trailer, 3" channel would be plenty except the end flanges are too narrow for the spring mounts. That's why I'm thinking tube as I will have a nice 2" wide area for the mounts, and its less likely to twist under load.
Thanks for the reply!

Frame strength for a trailer is just the same as for a truck, the taller the frame and wider the flange, the less likely it will twist. I would rather have 4"+ inches of channel then <=3" of boxed tube.
On my small 4 x 9 trailer pulled behind my Bronco II, the frame is 3" x 1.5 x 3/16 channel for the outside rails. But, it will never see 2000 pounds either, unless I get rear ended by a real truck.
