So this side is all from just two Mk. II copper miners. The bottom floor smelters feed into copper sheet constructors and the excess goes up to the second floor to produce copper wire and soon cable (just need to get more power before I expand the factory and that will require exploiting more coal deposits)

Over here is the iron production side of things

This first image is 20 smelters (I still have excess production I can’t take advantage of until I expand my power production)

Seen from the opposite side we have metal plating, rods, screws, and reinforced iron plating.
