huge corner desk

>>1158299
18 mm is thick enough if you have a support structure like some beams along the edges

3 cm of solid steel will be strong enough, but for wood I would suggest go at least 50 mm square, and ideally 75+ mm square

The legs are usually in the corners

can you suggest how should the beams be placed on an L shaped desk?

I was going to post a picture of my desk but I just got out of a wicked spat of depression and its covered in shit from projects and just general trash.
I basically built the same desk, its 8ft by 7ft and 30 inches deep.
table top is 3/4" so slightly bigger than 18mm.
Its held up like a champion, I beat it with things, I make guns on it, I work on PCs and its all held up perfectly.

this is good for beam placement. My desk is different but this would hold up well.

>And can it be stable using basic table legs with diameter of 3cm?

If they are steel and welded to a steel frame under the desk.

Even with side and back skirts, 3cm is very little for wood posts.
