I will need a beam above the garage door and another opening.
The designer of the roof trusses says 300mm wide, 290mm high, 14mm thickness in the upper/lower part, 8.5mm thickness in the middle. Approximately 75kg/meter.
The advantage of the beam is that it doesn't build much in height. Would an equivalent glulam beam end up around 600mm in height and be significantly cheaper?

Try and calculate with your data on the openings in Moelven's dimensioning program and you will get a hint about the size of a glulam beam.
I have a small table but the roughest steel beam is HEA220 and the one you describe sounds like an HEB300, which is obviously MUCH stronger. HEA220 corresponds to glulam 115x630. Take it with a grain of salt as glulam and steel cannot be compared directly since they have different properties...
5m wide gate at one spot.
And then I was thinking a 7m opening where the carport is supposed to be, but I might change my mind a bit regarding the 7m opening if I need to buy a beam for extremely expensive money.
Nothing on the upper floor except insulation
Found a used steel beam but it was an I-beam and 300x300x19 as well as 5.60m long. Such a one should correspond to and handle what I need above the garage door? A bit unsure about what the measurements mean. 19 cannot be the material thickness?

Spontaneously, it feels like insanely oversized beams for these relatively small openings. Especially considering what you will have above. I have five meters above my doors with a glulam that is significantly smaller than the monster steel beam you describe.
Doesn't it also matter what is loading the beam? It was the truss manufacturer who said this, so I don't have the knowledge to question it. For a 7m opening, HEA300 was required, for 5m you could get by with something weaker. On the 5m beam, I'll have about 4 trusses resting, and on the 7m beam about 6, so there will be quite a bit of load.Wester said:
But sure, I agree it's quite an extreme beam. Now it seems I might be able to get a second-hand beam for a reasonable price, probably cheaper than what glulam would cost, so it doesn't matter too much if it's a bit oversized? Except that there's a 1-ton hanging above your head.
Yes, of course, the load has significance. I myself have several roof trusses that load the beam. I have calculated this myself, so if it collapses, I have myself to blame, but during the winter's heavy snow load, I measured the deflection and saw no direct deflection. The upper floor is also furnished. But of course, there's nothing wrong with over-dimensioning, especially if you can get the beam cheaply. I used an overly strong beam in a construction because I got some HEA 220 beams cheaply.
Jumping into this old thread, as I seem to have the same question.
I have a flat garage roof with trusses that carry over the garage door. Today the door is only 2.4m wide, but it will become 4.5 meters. The roof/trusses have a span of 7 meters. I ran Moelven's program, and a suitable glulam beam is 90x315, but unfortunately, I don't have space for that height, so I was thinking of buying a HEA beam. Beijer made an estimate and said that an HEA160 would be suitable. However, I would like a second opinion to verify if that is correct.
Could someone be kind and make an estimate?
Best regards, Lasse E.
