Re: Too heavy

Though the 8020 extrusion itself may be lighter per foot than box aluminum, don't forget to factor in the weight of the additional fasteners and joining plates required to make it all stay together. If a team has access to aluminum welding equipment, it's probably lighter to weld a frame together from box aluminum than to make it from extrusion -- depending on its design, somewhat.
