One of the reasons that I posted this info was because I wanted to show just how poor steel tubing is when used to build a trailer. I was surprised at how weak it was compaired to its weight and price. Pound for pound, 2x2x3/16 is about the same weight as 3" channel (I'm being generous here), and 2x2x1/4 is about the same weight as 4" channel (again, generious). 3" Channel has twice the strenght of 2x2x3/16 tube, and yet it costs 30% less. 3" channel is about 50% stronger than 2x2x1/4 tube, and it's significantly lighter, and it's only about 60% of the cost. When you look at 4" channel, there's just no comparison.My point here is that unless a person has a free supply of square or rectangular tubing, there's just no reason to ever use it. Even if a person does already have the tubing, they need to realize that it's just not nearly as strong as they might think. I'm not trying to flame anyone here. I was just surprised by the information. I knew that the channel would be better, I just never expected it to be so much better. I honestly figured 2x2x1/4 would be about as strong as the light 3" channel. Looking at the numbers, to me its not really in the same ball park. Then, when you look at the cost, wow, a real eye opener for me.
