I'm interested in a single large garage door and ceiling. I don't know if only horizontal beams are called trusses. Either way, these are lightweight (low-budget) things, and I'm hesitant to screw heavy items into them as there's so little wood to screw into.
Then it occurred to me that I could easily add more rafters alongside these existing ones. The length is about 545cm. Does it require very large and expensive wooden beams to prevent sagging?
I'm having a bit of trouble seeing what it looks like above the opening. Can you take a picture that shows this a bit better? Since the roof beams run parallel to the doors, it can't require a major intervention.
The pillar between the gates is probably just to hold the frame.
It's open above the walls, so if I just know what dimension of roof beam I need to not flex on a 5.5-meter length, I can supplement with a lot of those to have something to screw the gate into.
Tempted to think about sleek I-beams in metal but hard to screw into, so glulam beam, i.e., very expensive?

I can figure it out for you if you tell me the following: Distance to the next beam on the inside?, what load is on the roof?, snow zone? Then the question is what kind of door you want to install? They weigh something when rolled up, right?
I've been searching for a while now, but the manufacturers don't seem to mention the weight of their doors.
But the extra beams are not supposed to carry the roof so the snow zone is not relevant.
Just meant to lie on top of the open walls and run along the real roof trusses. The only purpose is to be able to mount the garage door tracks. 5.5 meters from one wall to the other.

The gate is probably only supported on the sides, so the weight will be taken up by the posts beside the gate.
But sure, a 5.5-meter-wide gate will weigh quite a bit.

Looked more closely at the pictures and saw that the roof beams run parallel to the gates. Then, of course, the gate's own weight is of great interest. On the other hand, it shouldn't require much extra from the beam that sits over the gates, as it seems to be dimensioned like the other roof beams despite having more support.
If the gate together with the beam weighs 50 kg/m, you should use a rule that is 45x220 mm of C 24 class. It is unlikely to be heavier than that.
