Is aluminum extrusion strong enough for this project?
I'm making a custom desktop with aluminum extrusion, I'm thinking of using a mix of 2040 and 4040, it will be 2.5 meters long and supported from the sides and back, if I have no support in the middle of the span will it significantly bend as I want a "floating" look I will ofc have braces throughout the desk but nothing touching the floor at the front center. Ideally it should be able to take 50kg at the center without bending much if at all is this doable or would I need a stronger profile/material?
