Simple Structure Support

Hi brothers, in this challenge why I choose a support structure using a tube element. I think the cheap cost is not only material but also concerning the process of its fabrication, Using a tube then the process becomes simpler, just cut from the standard tube material and connect with some feet and connectors with welding. In addition, this structure is dedicated to moving vehicles, so that the push and pull can occur from the vertical or horizontal direction, therefore I choose the tube because it has the advantage to receive load from all sides.
