Also, once the zinc is burned off, it no longer has any water resistant property. Are you worried about rust at all with all that liquid/steam on brew stand? Particles have a tendency to migrate and I am paranoid about using something that isn't stainless on my rig. Is the idea to replace parts that have rusted on a regular cycle?

Just interested how galvanized steel is holding up so I can take it into account when I build my rig in the coming weeks?

Since I haven't brewed on mine yet, I can't really say, but since mine is all electric, I'm not really worried.

But thats my question... how is it holding up in USE and for those who use burners (i.e. any worry about rust once the zinc is gone) and any worry about fumes once the zinc is supposedly gone?

Brewed on mine twice now. The zinc will burn off and flake away and honestly its 12 gauge steel. I don't suspect that the steel will weaken to the point of being a concern for many years. The first time you use it give yourself some good ventilation and you should be fine.

A friend at work says he has "conditioned" galvanized by heating it multiple times with a torch (wear a respirator) allowing it to cool in between heating. He claims it takes a good looking patina without getting the nasty burned look later on. I was thinking I'll "condition" the pieces I use for the upper portion of my stand before assembling it so the entire top section of my frame looks the same.
Don't know if he's completely sane (we're emt's after all) but he has been welding and metalworking for quite some time.
Anyone know if this sounds right? I could have heard him incorrectly too.

I'm not worried about the steel giving way. Strut is perfect for this application structurally speaking.

But I think you helped me make a decision on this. The last thing I want is something flaking away on rig that can migrate into the brew. That and the fact that once the zinc has flaked off the bare metal is prone to rust (lots of liquid and steam around) which can also migrate into the brew.

Having said that, this stuff is EASY to replace if it becomes a problem.

Great rigs all around.

I just got my order and will be building this weekend. I ended up getting stainless for the part of the rig exposed to flames. I got strut and fittings. cost me about $200 more. kinda pricey, but I won some fantasy football money so I splurged.

Where did you get the stainless strut from? Good price?

They had free shipping, the best selection, and decent prices. I ordered 4-foot strut sections. The longer you go, the more they cost. It's 14 gauge.

The shipping was great. Got everything in 3 days. I'd order from them again in a heartbeat.

I'm using SS to build the top. I also got stainless bolts, washers, and fittings as well. The SS fittings are the killer. Some of them are ridiculously priced. I made a few adjustments to my design to keep the costs down.

The bottom part of the build will be regular galvinized. It will be a 2-tier system. If I do this right I think I can keep the flames away from all the galvinized sections. I still may need to order a few more SS bits and pieces if I run into problems.

The SS is probably overkill, but I'm weird that way. If something needs 2 nails I'll use 10. I pity anyone who has to take apart something I've built.

If you search back through I detailed pretty well how I did it, and I think it's a pretty robust setup. I too have a 1/2" NG line right inside my garage, in the laundry room. I do not have a dryer hooked up to it (ours is electric) so perfect to use for the rig. I got the good NG QD fittings ($$) but wanted to have real solid shutoff QDs for when I unhook and hook everything up. I went with simple PVC rubber air hose which has no reaction to NG (do not get butyl rubber, not compatible at all). My theory is that I'm always with in a few steps of my rig when gas is going to it, so as long as you have good QDs with a solid hose that is compatible with the gas there should be no issues. It's only hooked up to the gas maybe 3 hours every few weeks. Cheap, flexible, tough, and works great. I went with 1/2" ID hose, and I can run two 10-tip burners, but that is the max. I would guess you would not want the dryer on when you're brewing.
