Fixing plasterboard to steel beam?

[baker332]

Just to update, changed out the drill bit to a stepped drill applied loads of pressure and boom we're in business.

Tech screw took ages compared to the stepped drill bit not sure how you guys managed it (they are a decent set too).

Got there in the end, thanks all for advice.

Ha, I forgot this is a place for commercial advice

All joking aside, fixing plasterboard or other types of fire boards to steel beams for the purposes of fire stopping is not (or should not) be permitted, it should be fixed with metal angles or the boards fixed to themselves in accordance with the board manufacturers specifications and fire tests. Because BC or traders turn a blind eye for domestic situations is neither here nor there and they are either turning a blind eye or are uneducated. That said the stresses placed upon a steel beam and the time to control a fire may be significantly lower in a typical house setting compared to a commercial building (say several storeys high) so I get that there is a lower risk. Nevertheless you won't find a fire test done by a board supplier that shows timber to be used as substructure to fit the boards to a steel beam or column.
