Damn work getting in the way of posting brewing pictures!sorry guys for not posting any new pics i have been super busy with work. I did just brew another five gallons on it .I also put the casters on it . It is so nice to not have to stack every thing on on random items(chairs, bricks, 55 gallon drums LoL)
The wood will get warm. It will not get hot though. I personally have some left over hardwood flooring panels on each of my levels. You could easily go with MDF or even better yet a concrete fiberboard. The concrete is waterproof, heatproof, and fool proof.Allow me to rephrase my question.
I am thinking of building something similar to these 3 tiers with top level being 8 gallon kettle as HLT. What can I use to protect the wooden surface under the burner?
The only problem with MDF is that it absorbs water like a sponge and begins to blister up from it, not meant for wet locations unless you paint it to seal it.The wood will get warm.

Your approach is not terribly strong agianst the structure "collapsing." A diagonal is deisrable. The simplest might be an "X" of plumbers tape.My setup looks very similar to yours. Pic below. One thing I learned was I needed some extra support lengthwise to prevent the shelves from basically flattening out. I screwed an extra section of 2x4 where I circled on the picture to prevent that from happening. I only had the shelves attached to the support beams using a single carriage bolt per beam/shelf connection (where the arrows are).
Don't need an X on a small stand like that. One 2X4 (or even a 2X2 or 2x1 shelving) crossbrace going from one bottom corner to the opposite top corner on one side then on the other, another 2X4 corssbrace going from the opposite top corner (not the same side as the other cross brace) to the opposite bottom corner.Your approach is not terribly strong agianst the structure "collapsing."

I've had nothing but great success brewing with my rig. Spills are inevitable no matter what style rig you have. Mine rolls everything right off. And because I sprayed it with a clear poly coat I can hose it off with no issues at all. It is very sturdy in all directions now and would take quite a beating before it gave up any support at all. No accident would destroy this thing short of being run over by a car. Overall it's the best part of my entire setup making brew day WAY easier.Your approach is not terribly strong agianst the structure "collapsing." A diagonal is deisrable.

This said, your design and ~smontes's both have admirable traits. His, will shed a spill. ok. Your's, harder to clean, could contain one...! (His is outside; your's in inside...!) Your's could even have multi-level spill drains. A top most draining into a hose barb w/hose, could (if valved,) be washed and drained, or for a failure of a topmost container, drained below to the next level, to add capacity, and later drained, elsewhere.
Under kitchen sinks I often add linoleum and caulk the corners, & the sides 1" up. (If it runs onto the floor, you know there's a leak; instead of it runing under cabinets causing *serious* damage.) Similar effort makes these temporarily water-proof. Sinks, as it were.
I can see that a part of the structure, with sides & doors, or curtains, could be kept cleaner & used as storage. But if you have storage, having a 3-tier that collapses could be handy! Flatten and slide under your bed! (Orrrr... just hang on a wall... ;>) Add 2 large washers between wood at each carriage bolt, then use wing nuts. Remember the plumbers tape. Zinc is common & cheaper & stronger, but it's available in copper! ;>)
Trickier would be a rolling cabinet that has just a side that folds out. No harder, just all the figuring... the choices. SOO many choices! But less floorage and equipment, dust free. (In case yours gathers dust. ;>)
