I have four 4x8 trommel, shaker screen. If you are building gold mining equipment you need at least 1 of these screens. I don't know what kind of steel they are but it's to hard to drill. The opening in the screen is 3/8 by 1 1/4. See photos. They are new. I've been using them as a deck on a small trailer.

From what I can find the sell for about $1400.00 each. I'm asking $400.00 OBO each.text is best to start with. I will get back with you.

Thanks
