Re: Tube Versus Channel
Our frame is all aluminum tubing welded together. 1x1 1/16 wall for most of the upper structure, 1x2 1/16 wall for the base. As well as 1x2 1/8 wall for the base side beams that have the DTs mounted.
We do all of the welding in house and find that a welded tube frame is light and very stiff if done correctly.
It also gives us flexibility of the frame geometry and how we mount other components.
