IPE or HEA beam for balcony?

[matsca2m]

Sitting and studying for an exam in construction engineering, so I thought I might as well try to calculate this.

For glulam, I got 115x450 with fmk=32 MPa (strength parallel to fibers in bending) just as Justus suggested. However, I have not checked the deflection.

Alternative steel: HEA160 or IPE200. The deflection for the IPE beam at characteristic load combination I got to be 38mm (L/185).

Thank you so much for all the help with calculations.
Would you consider calculating a bit more?
What would be the deflection with an HEB260? What would be the deflection with IPE 220?

Of course.

HEB260
5.3 mm

IPE220
27.1 mm

Note that a HEB260 weighs 93 kg/m, i.e., 651 kg for a 7-meter beam.
IPE220 weighs 26.2 kg/m, i.e., approximately 184 kg.

IPE220 weighs 26.2 kg/m, which is about 184 kg.

I've encountered a problem and need to move the post 20cm due to a marker. What does it mean if I increase the span to 7200?
