Can I do a "stone floor" roof without pillar supports?

[FDru]

I mean, a kind of large roof?

I tried doing one like this, with wood beams across the top as supports:

But that middle piece just keeps falling out because the support is not enough.

(Also, yeah it's black marble but I assume it works the same as stone... correct me if I'm wrong.)

You could support it with iron cage or beam inside to add additional support. I think wood is not sufficient as support for marble.

I'll try that.. but as you can see, the wood beams did support quite a lot of floor so they do work somewhat.

Not the same, i thought so too, but black marble has more horizontal support than stone (1/2 vs 1/1)

You may be confusing the horizontal support the marble itself is providing your build with the "support" the wood is providing - that is to say, none whatsoever. Wood alone does not support any of the stonework: not stone, nor black marble, nor grausten. Wood iron beams, however, like iron cage walls, do provide sufficient support for all types of stone.

If you want to support a second story stone floor without pillars, using a lattice of iron cages will suffice.

I don't know what you mean by they provide no support whatsoever... without them I could only build the outer rim, and no inner blocks could be built at all.

Maybe you're wording it in a way that I don't understand it but if the wood beams are allowing almost the whole ceiling to be built wouldn't that still qualify as support?

Wood iron beams do, yes. Standalone wood doesn't provide sufficient integrity to support stone at all. If you are only using wood, the support is coming from the horizontal support afforded by the black marble.

I ended up with billions of iron pillars (tons of iron wasted...). Wood is just too weak.
For some reason, black marble eats integrity limit a WAY faster then stone or grausten do.
So i usualy avoid to use it and only build small tower's roofs with BM.

i managed to build 20x20m 2nd stage stone floor with iron beams and only 6x6 with wood...

you can do about 1 workbench radius (pretty large area, actually) with wood iron beams or similar. Items lend partial support, so if you went out 2 tiles and it breaks hanging off just 1, it may stick if hanging off two. So you can put a stone tile in a spot surrounded by 4 tiles that would break if any of the 4 were missing, etc. Sometimes that is useful. Be warned that as you go up to more floors, if the first roof/floor was red in places the second one won't hold, so the higher you go, the smaller its area is going to be -- forcing you to do a cone shape or reduce the bottom floors to match the tops. All that is with NO columns on the interior at all, just walls and ironwood lines across the seams (each ironwood supporting 2 blocks). Adding any interior columns (of ironwood, stone, or whatever) significantly adds to the area you can cover at the cost of having those columns in your way. If you want to go really, really tall you have to start getting creative with ways to run lines to 'ground' ... you can tie off on a tree you planted or hide dirt wall spikes inside your rock walls and so on.

Would having the beams sandwiched between the blocks work the same as having them below them?

I've been putting them between the blocks in this instance (each beam touching and "clipping through" four blocks) because I was worried the eitr refinery would damage them if they were exposed.

yes, if you want to hide them buried in the rock, its the same effect.
iron cage parts are immune to the refinery, so you can just put a cage around the thing with an iron gate to get inside to gather/feed etc.
