The first three years of our team we used 30mmx30mm Bosch extrusion. We absolutely loved the stuff because you could build things fast and you always had a place to screw something in without ever having to drill a hole. We loved it so much we bought a whole bunch of it. But then we got to thinking what it would be like to save some weight and weld it together instead of using gusset plates. And then we got to thinking that it would be easier to weld regular box tubing. And then we decided we wouldn't mind drilling holes. And then we weighed some box tubing against some extrusion and BAM! What a difference. That extrusion is heavy stuff. From the minute we found out just how much weight we were wasting on that, we went with box tubing and we are never going back.

While extrusion has its upsides, I prefer box tubing all the way.
