We build, rebuild, refine, renovate, and demolish steel mills all the time.
There is a very large brand new one in Mobile, AL.
Their designs produce different products than before the big collapse.
An example might be super sophisticated sheet metal alloys for car bodies. Or, ductile structural forms for buildings in earthquake zones.
Steel is not dead in the US, it is very value centered anymore.
I prefer not to work in the old mills, because they are such wastelands, and it's a very depressing environment.
In keeping with firearms manufacture, those ultra pure alloys we desire have to come from a furnace somewhere, just not at mega ton scale. Someone is tasked with making them for us.
