Steel plate from scrapyard

Tags: #<Tag:0x00007fa360f7b628>

Hello everyone!
I need approx 500x1000mm 10/12mm thick steel plate, if it comes in 300x300mm or 400/400mm pieces thats fine for me. also a 4x400x100, and 5x400x1000mm piece.
This would help a lot to get the rose engine up and running.
Does anyone knows a good and cheap scrapyard who’s selling and have this stuff on stock?
Thank you in advance.
