Looking for Used 2" x 2" Aluminum Lanai Screen Frames

[propjob]

Is anyone in TV currently enclosing their lanai or have near term plans to do so? I'm looking to acquire the 2" x 2" aluminum frames that hold the existing screens and the connecting L braces; color doesn't matter. They would be perfect for a DYI project I am planning. Need approximately 50 linear feet in total. Not sure what the contractor usually does with the existing lanai screening material but my guess is that it's scrapped/recycled.

I know Lowes and Home Depot sell these but looking to get the material at no to low cost. Thx!!

I saw this post several days ago either here or on another site. Just go to you local scrap yard, at the rate they are inclosing lanais down here the scrap yard probably have tons of them.
