Hello!
My first post here! I'm planning to remodel my workshop, which used to be an old carpentry shop. The workshop is built around an old garage. The garage's exterior wall is now an interior wall that supports the roof truss joists. But my idea is to remove these load-bearing walls to create a more open floor plan. The red lines on my drawing indicate the walls to be removed. And the green line is a beam I want to install to support the roof joists. These are straight joists running along the width of the workshop, so no truss framework, with a light metal roof on top. The garage is 8.7m wide. I am aware that 10m is long without support columns. But it's important for me to remove the walls. Do you have any tips? What type of beam? Or any other opinions or thoughts!
Best regards, Martin

Such people who work with it have a certain title. I don't quite remember what. If you think of it, you can call such a company. After three tries, I reached a super enthusiast. He brought his old calculation books and came over to do some calculations. Mostly he talked about his other great works, though, but I did get answers.
I do think, however, that you can basically go to an iron seller and just ask for the most durable I-beam they have and take the largest one you can fit without it looking silly when you manage to cover it with plasterboard, etc. For the small beam I chose would support 3-4 times more than I even needed.
I recall people suggesting to me that Beijer had some calculation method... Or if you go to a place like XL-bygg, they calculate beams too. Maybe not metal, but who knows, maybe they can help you anyway.
Now, I don't have 10 meters... There will be some load on the pillars... Is it stable under the house?

The one I found belonged to some consulting company that calculated arenas, industrial cranes, etc. They got a lot of work during the snowy winter when municipalities and others asked them to come and calculate whether their roofs would hold.

I know, it got stuck at the beginning. but you can probably find answers in old topics if you search for metal beam or something like that.
The metal sellers themselves have quite a good sense of which materials have the best durability, etc. XL-bygg sells roof trusses and other things that they calculate for you, so if they calculate what kind of wooden beam you should have, then maybe it's easy to find a metal beam with, for example, double the durability...
If you're going to be fanatic, these should be painted with fire protection paint, but the poor wooden beams will probably burn out first anyway, I think.

Which snow zone applies?
Are the rafters 8.7 m long and supported on three supports?
Flat roof? Roof pitch?

Hello! yes they are, but they are spliced at the joint by the wall I want to remove. i.e. 3supports. It is a flat roof with very little slope, maybe 5 degrees, hard to estimate. Living in Västra Götaland!

Well, and if you browse to http://www.byggherre.se/documents/Dokument_offentliga/Remisser/060124_Bov_F%C3%B6reskrifter_EBS3.pdf and check which snow zone your municipality is in, we can find out the correct snow load.
OK, it looks like you need a steel beam of dimension HEA280. It is 270 mm high, 280 mm wide, and weighs 76.5 kg/m.
Assuming you are not at risk of additional snow from adjacent buildings!!! In that case, the dimensioning does not apply.
