Metal panels at wood framed garage floor

Came across wood framed construction and was wondering what is the intent of these panels. Fireproofing or just to catch water percolating through the wood framing.

Looks like a cheap-ish interior finish similar to a standing seam panel. I doubt it's for fireproofing, because that's usually gypsum boards in these cases. It's not for catching water, because waterproofing is applied to the top of a deck, not the bottom of joist.

Probably water tightening from the garage to the wood. Someone could wash a car in the garage, and want to protect the wood from spray.

Could also have been a carport sometime in the past, and used the metal panel as soffit material.
