Hello
In connection with the renovation of the kitchen, we will redo the floor joists. On the upper floor above the kitchen, there is currently only an attic, which is an upcoming project. The floor joists are currently flexing, and the ceiling in the kitchen and the floor in the attic need to be redone. The dimensions are 5600 x 5900.
I am considering an iron beam of 5600 to divide the span of 5900 and then new joists next to the old ones, either 45x220 or 45x195. The reason for the iron beam is that I don't want to lower the ceiling in the kitchen or have a too large box that I assume a laminated wood beam would create.
Am I thinking correctly about the construction?
What dimension and model of the iron beam?
Grateful for insights.

If you switch the decking with a steel beam, you will need an HEA180 since the span is as long as 5.6m. If you place this under the floor joists and wedge underneath so that all the floor joists rest on the steel beam, you don't need to reinforce the floor joists themselves. However, note that an HEA180 at 5.6m weighs 200kg and is not so easy to handle indoors.... You should also ensure that the HEA beam has supports (pillars, etc.) that can manage bringing the load down to the foundation. We're talking about just over 2 tons at each end of the beam. Please share more about how the load is being taken down!

Is it right to use a steel beam or should I solve it in another way?
At one end of the beam, I can create a support in the form of a post (dimension?), while at the other end, it's a bit trickier. There is a wide patio double door with sturdy posts on either side. I was thinking of welding a longer flat bar (perhaps as long as the door is wide) to the end of the beam and bolting it to the beam above the patio door. Is that a good solution?

I believe that anasune means that the beam, in turn, rests on sturdy joists on either side of the door. So I guess the question is whether the beam reinforced with flat iron will be stiff enough (I don't know).
One more thing you need to take into account is what the foundation looks like where these forces are transferred down. For example, if you just place a post on a concrete slab but not over an edge beam, I think it's a bit borderline whether the slab can withstand the load. I think the advice you can get here should only be seen as "preliminary"; if you really are going to do this, you must hire a structural engineer who can perform accurate load calculations (and take responsibility for the calculations). If nothing else, this is a measure that requires at least a building notification, and you must be able to present the construction before you can proceed.

The load is transferred to an exterior wall so the strength of the slab/edge beam is not a problem. When it comes to fastening, it's probably best to over-dimension 
I can arrange a support underneath since there is a good distance down to the patio door.
Does anyone know anything about the price of steel beams and a good supplier?
