Both these numbers assume no heat loss. So you can figure that it will be much less at contact with your stand.

Here are some good links. Your stand should be fine

By the way. That stand looks sweet.
Without starting any pissing war most aluminum alloys decline rapidly if exposed to elevated temperatures although some retain significant strength to 500*F. Aluminum melts at 1,220*F not"2,200*F", deep red color steel your at 1,300*F. If aluminum is exposed to elevated temperatures it weakens due to mainly the coarsening of the the fine precipitutates on which the alloy depends on their strength. With the reply of the steel plate melting which is way above the deep red of 1,300*F and the 1,220*F of aluminum is the reason why I replied in ther first place. A metal frame insert to hold your keggles or pots exposed directly in the flame that is bolted to the aluminum frame plus a heat shield protecting the aluminum from any flames pushed to the side by wind or the burner cranked up high.
If the automotive world could get pistons to operate at these higher elevated conditions with a melting temp of 2,200*F we would have super clean and higher efficiency running internal combustion engines, the limiting factor would be the ignition temps of the gasoline by thes elevated temps. This in the ignition range of app 875*F causing preignition detonation and self distruction of the engines.
Try www.steelforge.com as a example, click on aluminum then click on "Learn More".

NO......... no pissing contest implied I am sure.

I hit the wrong key. Too many 2's I meant to put a 1. All I am saying is you would need a closed environment of direct heat for those burners to melt the stand. With open air and regulated use. His stand will be fine.

Here's my All Electric Herms...Using 3 Blichmann's 20G/15G/15G, 2 5500w element's, one in HLT, the other in the BK. A custom controller made by Brewmation, 1/2" Cam & Groove disconnects, 50' 1/2" stainless tube for the HEX, 2 march pump's, one to recirculate the mash, the other to recirculate the HLT continuously. The stand works but is temporary, until a figure something else out. Just brewed the first 12g of Oatmeal Stout last week, went pretty smoothly. It heats and boils as fast as any burner I have used.

I just use a silicone hose that rests on the grain bed, and batch sparge.

You would have a lot more NOx formed.
