I plan to remove a doorway into a hall. The wall is load-bearing, and I would like to install a steel beam with a maximum height of 70mm to support the ceiling. The opening will be 150cm wide. The house is a single-story townhouse with a flat roof, so the load is not particularly high, I live in Stockholm so we don't have that much snow. It doesn’t matter much if the beam bends a little under maximum load.

Are there any suitable steel beams that should meet the requirements, and should it be a U- or H-beam?

Best regards,
Michel
 
What kind of house is it..? Frame construction, brick etc. Is the door opening in an exterior wall or an interior wall, along or across the direction of the roof trusses?
 
It is a single-story townhouse built in 1957 based on wall and roof elements (Elementhus), so there is no traditional framework. The doorway is in the middle wall of the house, which has a total width of around 5.5 m and crosses the direction of the roof trusses.
 
So the roof trusses rest on this wall, even though it's only 5.5 meters in span? Are you sure it's load-bearing?

Edit: And now I realized that it's a flat roof and not a traditional roof structure. I think someone else should answer how you should dimension it, this is outside my area of expertise.
 
Anyone know if there are HEA or HEB beams that are a maximum of 70 mm high?

In the lists I've found, there are no measurements, only product names like "HEB 100". Is "100" = 100 mm in height?

Yes.
