Galvanized base stack?
Hi folks, Just a hobby guy here, season is coming on fast and I need to build my base stack. I have a sheet of 20ga Galvanized steel. Can I use that to make the base stack safely? Base stack would be 3’ by 18” at the base. One open side of shack and one side is stockade fence so it is well ventilated but I am concerned about off gas from the galv metal. The base stack will be 6’ from the fire box minimum. AUF in the box. As always, Thank You!
2012 4 taps and a bunch of propane
2013 12 taps and a new home made 1x2 flat pan fit to an old wood stove, more propane
2014 40 on tube flowing down hill to a 1x2 and 3 steam pans on emergency arch. (Drowning in sap)
2015. New 2x5 flat pan and much better arch. 1x2 on new rocket stove ( this thing cranks, can't wait to use it) 60 on tubing into 250 gal tank. 6 on buckets just for comparison and a little extra!
2016. Not a good year with the mild weather winter.
Galvanized base stacks are common (which doesn't necessarily make something a good idea). Since your shack is well ventilated, I think it likely that any off-gassing will simply rise up and out the cupola with the steam. It also seems likely that the vast majority of any off gassing will happen quite quickly.

Base stacks mage using galvanized are still in use throughout much of the maple world. I'm not sure how long 20 ga will hold up, I think most galv. base stacks are a little heavier, but you certainly will get a few years out of it. As that needs replacing, consider a SS base stack, in normal use it should last several time longer than the galv. one.
Dave Klish, I recently bought a 2x6 wood fired evaporator from A&A Sheet Metal which I will be converting to oil fired
Now have solar, 2x6 finish pan, 5 bank 7x7 filter press, large water jacketed bottler, and tankless water heater.
Recently bought another Gingerich RO, this one was a 125, but a second membrane was added thus is a 250, like I had.
After running a 2x3, a 2x6, 3x8 tapping from 79 taps up to 1320 all woodfired, now I'm going to a 2x6 oil fired and a 200-425 taps.
I've had a galvanised base stack for about 5 years that I got from bascoms. It has held up well without any holes or rusting through yet. The off gassing pretty much ended after the first boil and wasn't too much of an issue with the windows and cupola wide open. I would use what you have and plan for stainless on your next rig.

Looks good! A lot more fancy than my galv base.
