We should be buying our first couple of shipping containers next month. I was looking up online the best way to cut containers and it looks like Plasma Cutter is the way to go. However, how do you put them together? Is standard welding the way to go? Do you to put them back together before you put them in their final resting spot or should they be easy to move once put together? We are looking at getting 2 40ft containers and 2 20ft containers. We were going to put together the 2 20ft containers first and the when we can afford it get the 2 40 foot containers and put the 20 ft on top of the 40. Just want to make sure I do everything in the right order. Anyone have experience with these?
