You want the bits of extrusion to clamp to each other face to face not cantilevered up on thin plates.
But then it can't rotate? Am I missing something very obvious? The angle of that beam needs to be adjustable.
I could do 3mm CR4 instead but it saves 5 quid on the entire order so figured I'd go for 4mm.

The arrow was supposed to be pointing to the airgap between the two bits of extrusion where all the load will be transferred through two thin plates. I lack paint skills.

Re:price
You don't need S355, fixtures need stiffness not strength. Better steel gets you a better yield strength but the stiffness will be the same.
That price will go down if you add more bits. Small orders are priced WAAY higher to account for set up and office time.
