However an alternative way of adding open space is to take sheets or coils of metal and put it through an expanding machine.

Most engineers rely heavily on mechanical fasteners. 6 types of sheet metal joining techniques folding tab joints. How to join sheet metal parts. Folding and adding bending tabs is one of the easiest and most economical way of making moderately strong joints in sheet metal parts that will permanently or semi permanently attach to one.
