Steel beam and fireplace

[adde82]

Hello
We have extended our house and on the ground floor, there are two steel beams supporting the upper floor. One of the beams is built-in but the other is fully visible. Next to this beam, a stove is planned to be installed (it's included in the building permit) and my question is whether there are any requirements for how this beam must be protected? Is it enough to enclose it perhaps with OSB and gypsum (how thick should it be, if so) or is something else needed? It gets warm around the stove, of course, but the steel shouldn't be affected at temperatures below 700 degrees, which it shouldn't reach... The stove will be about half a meter away from the steel beam/column.

Steel has the property that at 700-1000 degrees, the beam softens and just buckles, whereas a wooden beam must burn through.

The stove probably doesn't affect the beam, but otherwise, the beam should be fire-protected (thermally insulated) with double plasterboard. The chimney shouldn't get that hot on the outside if it's properly constructed.

Thank you. Yes, it might be just as well to do so. However, I still have to figure out how to apply the drywall since I have to frame in some way to get the drywall in place...
