Steel Legs

[TBM66]

Due to the layout of my patio using steel legs would be better looking than the CMU foundation.

I would evision using steel posts like you see in basements, set in concrete footings to 48 inches. I would lay them out like the 5 dots on a die, 4 corners and 1 middle.

Anybody have experience in this approach?

Would you use steel legs in place of the block stand, above ground, or are you talking about below-grade piers, or both?

They would be cast into concrete footings 48" deep underground.

I used steel legs on my recently completed oven.
My main concern was that I probally will be moving soon
and wanted to take the oven to my new home. The design
will allow the oven to be moved off its stand onto a flat bed
truck to its new home.

I'm pretty sure most home buyers dont think of a prebuilt pizza oven
as an asset.

The stand sits on top of a rebar reinforced concrete slab. So far no problems.

Another advantage is it allows for wood storage underneath the oven
which is accessible from all sides.

good luck with your oven.

TBM, if you do a search for "sonotubes" on the forum, you'll find some people who used concrete pillars (with sonotubes) in the formation you described: 4 corners plus one in the middle, below the frost line. I don't recall anyone using steel alone below grade, so you might be breaking new ground (not a bad thing!). Is there a way to prevent corrosion of the steel, though?

[TBM66]

DB, just to be clear the below grade portion of the steel legs would be encased in concrete. So presumably no corrosion.

Sorry, my bad. So the hearth slab will rest on those 5 steel legs instead of having a foundation slab and block wall? Sorry to drag out a topic I know little about; I'm just trying to envision your plan. I don't see why it wouldn't work if you've got enough rebar in your hearth slab, but I defer to the experts.

[TBM66]

No worries.

You got the plan. 5 legs embedded in concrete footings. Hearth deck sits on top.

Plans may change. She Who is To Be Obeyed has indicated that she doen't prefer the look of an igloo on a slab, instead she prefers a full rectangular structure.

Still negotiating.

Here is a snapshot of my steel foundation. the top is flat which helps
distribute the weight of the hearth/oven along a larger broader area. I think
this is important to dstriubute the weight along a large area. I am a woodworker and think of it as a drawer bottom. The bottom of a drawer
alone is thin and weak, but when supported on four sides it can hold much more weight than it could on its own.

My hearth simply sits ontop of this steel stand and I intend to lift
it off with a forklift and move it to my next house.

The hearth is built according to the available plans. I also went ahead and
welded my rebar together to create a stronger lattice type structure.

Perfect. That's awesome. May I ask the spec of the steel you used? And did you fabricate it yourself?
