Custom aluminum fence in Baton Rouge

I need to replace the last 4 feet of fencing on one side of my back yard. Only problem is the fence was made by Specrail who went out of business last year. They were the manufacturer who supplied this fence to dealers around the country.

Here’s the problem: the fence was their “old style” before they even went out of business meaning that they could provide parts for it but no longer sold it on a regular basis. The measurements of the individual components are a little different than what I’ve been able to find and the spacing is also different. I was looking to see if I could find individual components and make the panel myself but that seems to be a no go as well.

So- anyone know of someone in the BR area who actually makes aluminum fence components and doesn’t just purchase from large manufacturers and install?
