Thank you for you reply pippin, I will make a draft with LShape (180x90) x 2 (It had approx 17kg to the gantry weight).

This evening, I make a review of the different 90° connecting option between my aluminium profil (40x80, 80x120 and 90 x 180, all have 10mm slot). In the picture below there is the most commun choice with the price in euros/unit. I don't consider square, I think it is the less stronger connexion.
I think I will probably using T-matik (1e46 + 0e30) from Systeal of milling connector from Motedis (1e44).

T-matik :
- a bit more expensive that the Milling connector
- simpler (one type whether 0° or 90° position and no machining)
- stronger connection that milling connector ?
- Eventually I can fill the profil (sand, concret) the connector don't create hole

Milling connector
- a bit cheap
- need more effort
- creation of hole
- perhaps less stronger (torque isn't apply directly)



As usual, I am really interested by you experience or opinion
