Thought about using square tube. I was concerned that any water that got inside would just cause it to rust. It seems a lot of the equipment trailers Ive seen are build out of C-channel.
!
Weld the open ends of the square tubing shut and they won't rust inside. There is not enough oxygen in the tubing to allow rust to form. I cut a piece off my trailer tubing after about 6 years to make a change to it and it was not rusted inside. It takes continuous exposure to oxygen and moisture for rust to take place. That's why they like to store airplanes and big equipment in Arizona, very little moisture to cause corrosion. You can also drill a small drain hole in any piece that you think will be likely to get water in it so it can drain and dry out. The two uprights at the end of my trailer have been on the trailer since it was built 10 years ago and they have not shown signs of rusting out. They are open at the top with a drain hole at the bottom.
