Concrete – Guidelines for poured concrete over corrugated metal

concreteconstructionframingsteel

It seems common in some commercial construction to use corrugated steel plates to form a 'deck' surface which concrete is later poured onto. The combined steel/concrete then forms a very strong floor surface.

I am interested if there are any guidelines for doing a similar process on a residential or DIY level. For example, an elevated shed floor could conceivably be constructed out of metal roofing over wooden joists, with concrete poured on top. Perhaps even a freestanding deck.

Ideally I'd like to find out if there are standards or guidelines for the wooden deck framing, metal gauge and other dimensions, if rebar or mesh is to be used, concrete thickness, etc. And/or what building codes might have to say about this.

Here's a commercial example just to make the general idea clear:

I don't know if such a guide is published but if this is ever something done by contractors on a small scale then… maybe.

Also though I'm in the US where wood framing is common in many countries masonry seems to be more typical, so any global examples/information would be welcome also.

Thanks!

This is not a complete answer to the question but it is at least a residential example of this kind of construction. It shows how a front porch is put together.

So it can be done although the backgound of whether this was a custom engineered project or how else the design was arrived at is not clear.

Steel C-channel is used as "joists" (the C-shape is facing down):

Steel deck pans are installed. These do look generally similar to roofing but seem like a purpose-made product:

The pans are cut to fit and overlap to some extent: enter image description here

Concrete is poured over the deck pans:
