Something like this for false bottom mash tun

[MikEH86]

We have these stainless steel screens at work. The holes are around 5/64th's was wondering about using that to create a mash tun false bottom? Or is that to course of a hole? Will attach some pics this one is a lower grade and has some rust on it. Won't be using it.
Is there any huge differents between BIAB and mashing? I'll be switching to pre milled grains from the supplier.

Looks like it'd work! Do you have the ability to add some legs to it- welded or otherwise?

Yeah how much space is usually required. The sheet has a curve to it how ever probably not enough.

It really depends on where your ball valve is. And youll probably want something to support the bottom even if there is a curve as if its not thick enough it will start to collapse under the weight of the grains/water.
Are you doing BIAB or using mash tun?
Theres a lot of questions, like what is your equipment set up currently and what are you looking to change?
