Under chassis panel

Hello, everyone!
Is there any known alternative for the sheet metal panel under the chassis?
From what I saw, it doesn't protect anything in particular, but it constantly scrapes the floor when entering the garage.
In the medium term I will fix the garage entrance, but I am considering disassembling the piece and sending it to my trusted blacksmith to make this lower piece.
Some experience?

It is a stiffening plate to reduce body shake.

So its main job is to give strength to the chassis, right?
If they are a few centimeters shorter, shouldn't there be a problem?
I'm even thinking about using a completely flat, but thicker plate.
