Default My new false bottom. Will it work?

I just built this false bottom for BIAB. Basically the only purpose it needs to serve is to keep the grain bag off the bottom of the pot so it doesn't melt during mash out or if I should need to bring up the temp of the mash for any other reason. My only real concern with it is that the grid is aluminum and the bolts and washers are stainless steel. (I tried to get aluminum ones but couldn't find them anywhere.) Anyway, I've heard there can be some corrosion issues with the two metals being in contact with each other. Do you think that will be an issue with my beer?

That thing looks great. Galvanic action is what I think its called. I would think that it would work out great. Given that it is only used for a short period of time at pretty much low heat, and the fact you are going to clean it up after you brew, I would guess that you don't need to worry too much. Over time it may have a problem if it stays wet. Use the H--- out of it!

Well I decided to boil it in some water for about a half hour before it's inaugural use this weekend and it turned pretty black. Hope that's normal.

On a side note. I thought it was pretty crazy how when I pulled it out of the water after a half hour boil it was cold to the touch within 5 second. Seriously, it was ice cold when I expected it to be hot. That was crazy.

Aluminum turning black when left in boiling water is called conditioning and it's both normal and a GOOD THING... It's, basically, an aluminum oxide coating that is a barrier between the aluminum and what's in the pot...

Don't scrub it off and you'll be a lot happier...

Welcome to the thermal conductivity of aluminum...

Glad Goldiggie knows a little about metals. I was scared for a minute on that one. On another note your screen holes look pretty big. Guess I'm trying to say you might get a lot of grain through it until it establishes a good filter bed. It could clog your drain pipe or dip tube. Good luck with it.

Umm, Snake??? See in the first post, he's using it with the BIAB method... So, zero worries...

You will get some galvanic corrosion between the two metals. SS and aluminum are not close on the galvanic chart. While it may be okay for a couple of brews, it would be worth it to get a SS grate to go with the SS bolts.

That is a nice thought but I'd rather keep this cheep and simple for the time being. On the other hand I wouldn't mind purchasing different bolts if there is another type of metal that would be better suited to be in contact with the aluminum grate. For instance I almost purchased galvanized aluminum bolts but I wasn't sure what galvanized meant. It sounded like some sort of chemical coating that I might not want in my beer.
