The essay looks at sheet metal and heavy-metal fabrication, drawing attention to dissimilarities in material thickness, techniques, and uses of the two processes. Sheet metal is best suited for thin materials such as those used in lighter structures like electronic casings; whereas heavy-metal fabrication is most appropriate when dealing with thicker and stronger materials needed by heavier-duty industries like construction. The two aspects are important in both fields, but vary greatly especially in handling and inspections. The decision depends on what a particular project requires.
