I am going to build a patio roof measuring approximately 8x4 m. The roof will be built on 6 posts 90x90, and the other support beams and roof rafters will consist of glulam 90x180. I am considering how the posts should be fastened to the support beams and have come to the following conclusion:
What size bolts should I use?
I was thinking of using flat steel 60x5mm on both sides.

Opinions?
I think it will look both nicer and be better with a perforated plate/nail plate (e.g. 80x200) fastened with anchor screws.
Agree, nail plates and the like should not be visible. I definitely believe much more in your own idea. I'm not quite clear on the circumstances, but it should probably work with construction screws from above and down into the column.
In my world, visible nails/plate connectors and things like beam shoes are the ugliest things you can have in a visible construction.
The entire construction will be painted black.
Puhh, I got scared there
Of course, you should have flat iron, preferably with slightly rounded corners and edges, maybe even massage the edges with a ball-peen hammer until you're satisfied
However, I would go up in dimension on the posts for a more stable appearance, but that's a matter of taste.
Have you considered diagonal braces for stability?
Good luck

I understand your idea with the ball-peen hammer, but the patio roof should be as minimalist as possible. Think away 1700s, allmoge, garlands, and all that stuff straight lines, hard!
In my world, visible nail/bracket plates and for example joist hangers are the ugliest things you can have in a visible construction.
The entire construction will be painted black.

Now it wasn't clear from the thread starter that it would be visible, so I agree that bracket plates won't be the prettiest. But a half-meter-long flat iron that's half a centimeter thick is possibly even uglier in my opinion. I think a black-painted bracket plate blends in better than a flat iron.

Diagonal braces, yes, but I'd rather avoid those. I think I should be able to solve it with iron.
You cannot make a freestanding structure sufficiently stable using your iron unless there is some attachment to a type of house structure. The roof plane can also be used for stability, like diagonals.
To size the bolts, you need to know the force and any potential moments that occur at the connection. The bolts are then checked against factors such as shearing, sufficient edge distance, checking the nail plate, etc.
