I am planning an extension with 49m2 of living space (garage in the basement). I currently have an H-beam 200mm that I intend to use as a load-bearing element in the garage ceiling. The span of the beam will be about 6.8m. I would prefer not to have any support pillar (it will get in the way of the double garage). The question is whether it is sufficient for all stresses, or do I need two 200mm H-beams when the span is that long? Roof pitch 27 degrees. Garage ceiling height 2.2m. Living space ceiling height 2.5m. Garage wall dimensions L.7.3m W.7.4m consisting of cement stone. Grateful for any answers.
I have the same problem with a garage build with an upper floor 7x10 m. I want to have an almost 7m long H-beam and want to avoid support pillars in the garage. I don't know how to solve this.?
I think the beam might bend, deflect, by its own weight 1-2cm without pillars. Need to check this.

You don't mention if it's an HE-A, HE-B, or HE-M beam. Or perhaps even an INP or IPE?
It's more than the height that matters for strength. Flange width and flange thickness are just as significant. And if the beam is too weak, it's possible to weld a plj. on both the top and bottom to increase load-bearing capacity and reduce slenderness = deflection.
Measure the beam a bit better and get back to me, and I'll see if I can help you.

The beam will be 6530mm long.
Another option is to build with kerto beam from moelven. 6.5m long beams with cc60 should suffice with a 45x360 beam to create a stable floor, if you glue-screw a chipboard on top. The kerto beam costs 173kr/m +VAT. With this option, no supports are needed, but the downside might be that the floor layer becomes thicker than with a metal beam, and the construction becomes more expensive than a metal beam. I write metal beam because I don't know the difference between steel and iron.
It will be exciting to see what you come up with Builder.

Found a price list for steel beams. It's a bit down on this link:

Yes, it can be anything with this single data pointper hammare said:
My answer was really intended for Tokri who had an existing beam that he was planning to use. Mostly what the beam would withstand in terms of load-bearing capacity.
You ask about the dimension for spv. 6.53 m and then what? How large is the load area supposed to be on this beam and how much/sqm? That is, how wide is it across from the beam's longitudinal direction to the nearest wall p.b.s., and how many kilos/sqm did you intend to load that area with or rather: what is the space? Residential? Other?
You can read about the difference between iron and steel on this link:

Metal is something entirely different. Mostly copper, brass, and other alloys. Gold and silver are considered noble metals.
