Civil Engineering/steel deck concrete on wood frame support

Question
Mr. Arshad,
I am at the initial stage of planning a residential family project, utilizing as many cost effective methods as possible.
Target Object : 3 storied apartment 12 * 13 meters, max span 6 m

Walls - eco stabilised bricks 400-800 psi

I came across an article discussing the use of corrugated galvanised steel sheets + concrete to make slab floors.

I was thinking of using this for this project,  that is a concrete beam, attached with wood frames, the steel sheets are then nailed onto the  hard wood cross frames to make the hanging frame , on to which a 10-12 cm concrete layer will be poured.  Could you advise if this makes technical sense or the wood will break ?  Any tips and advice ? Thanks for your help.

Answer
Hi Jeff,

Corrugated sheets can be used as permanent shutters/formwork for RC slabs, and if they have any types of ridges or ribs that can form a good positive bond with the concrete it can also contribute towards the rebar requirement by composite action.

However, as for the rest, I do not quite understand your structural system with hanging and cross timber frames, so if you can attach a sketch I can commnet further.
