I recently inherited a large piece of property that has a few metal barns on it. One of the metal barn doors was hit by a large log in a storm and damaged.

I do not know the first thing about barns or barn doors, and I'm trying to figure out what the right solution is here - do I hammer it out and replace the missing framing wood? Should I order a new door? Who would I order that from? This barn has been standing for atleast 30 years at this point, but it's in otherwise great shape.

I'm completely new to this stuff, thanks in advance for any help.
