Help with Metal infrastructure to floating desk
I dont know if this is the right forum to ask my question but I'll ask any way.
I want to build a floating desk. My goal is to build a strong desk that can support the weight of person sitting over it.
I'm considering using one kind of methods being used to build floating stairs. Metal infrastructure(steel/iron) and wood casing,
In a way that the wood casing will threaded into the metal skeleton, and the metal skeleton will fixed to the wall with screws.
I intend to use steel rectangular tube - 40mm by 100mm, length of 60cm and 2.5mm thickness. Each welded to a steel plate - 200mm x 100mm with thickness of 6mm
and with four holes for screws (12-10mm diameter, 6cm deep). I plan to use 8 tube spread evenly on the length of about two meters.
Like in the photo below, in one different - the tubes will spread horizontally and not diagonally.

The wall is concrete(poured) with thickness of about 20cm.
My questions:
Assuming the top wood plate will support the weight and not bend or break in the empty spaces between the tubes, Is my plan will work? is the steel frame is strong enough to meet the demands?
If so, I'd love to hear comments for improvement especially regarding the tubes and screws sizes(to decrease? to increase?).
If not, I'd glad to explanation to why not and other solution.

That's really the sort of question you need to take to a structural engineer. Failure could be costly and for something like that a forum like this is not really the best place to get dependable advice that you can confidently hang your hat on.
Sorry.

From what I can tell, the weakest link is not the steel support structure (which is probably overkill) but the way the steel/top is attached to the skeleton.
I'd like to see a couple of diagrams before making any sort of commitment.
You also did not say what the design and dimension are of the steel skeleton.
