Clean, but otherwise sparse.  It wouldn't be industrial so much as functional, if that makes sense.  So there isn't much in the way of heavy equipment laying around, or oil stains, but neither does it have anything that would be described as luxurious.  It would have a pristine floor, no rust on the metal struts, the paint looks new without any chips, everything is well oiled and well maintained without there being any grease or similar 'dirty' substances visible, etc.<br/><br/>Sorry if I didn't describe it well, I'll try to include more detail in the future.
