Hello!
A wall has been taken down and supported with an HEA12 steel beam by a construction company. Now that the plastering is done, the beam in the ceiling looks gigantic, like something that should be in an industrial space. Now the beam, plus plaster, measures 20 cm in height and 24 cm in width. I was thinking of complaining to the builder, but I'm wondering if anyone else has experience? What dimensions have you gotten for plastered-in HEA12 beams?

Sounds like they built the box with wooden studs.
Do you know if there are fire requirements for the enclosure? Otherwise, you can just build with LP50 profiles to keep it minimal. It’s also possible to glue the drywall directly to the steel if you wish.

I wouldn't think there are fire requirements. It's a regular house with a standard steel beam. They haven't used fire gypsum, for example, so I see no reason why there would be specific fire regulations. Thanks for the tip, I'll tell the builder!Matti_75 said:
We replaced a load-bearing wall last spring and the fire requirement was El30. We chose fire-resistant drywall as one layer sufficed for el30, the alternative was to paint the beam with fire protection paint or double regular drywall. That is, you don't have to use fire-resistant drywall to meet the requirements but it builds up less.S Sophia Jönsson said:

how did you know there was a fire requirement? According to what I've been able to read, there's no fire requirement in single-family houses since it's counted as a fire cell. Asked the builders and they had used regular gypsum board. I just think they used one layer of regular gypsum board.
If he has already plastered the ceiling, then he should attach the rail to the beam instead. There are special clips or you can nail or screw them in place. If you only see problems, you'll have problems. If you see solutions, the world is enormous. You can guess which type you're dealing with. “This is how I've always done it.”
Honestly, I don't quite remember where I got the information about fire requirements (it wasn't easy and our builder wasn't entirely sure either) but I believe it was about load-bearing structures, not fire spread which fire compartments are meant for, and ensuring enough time for evacuation.
Personally, we wanted to cover the beam with plasterboard anyway, and using fire-resistant plasterboard that met that requirement had a marginal difference in thickness.

It's likely there are RE30 requirements for a steel beam in a single-family house. 2 layers of plasterboard or 1 layer of protect F plasterboard. But as Matti says, it can be done so that it adds just a few millimeters more than the board depth of 26 or 15 mm. Or fire paint.
