I suppose you're asking about women in general in the UK, Dims? There are hundreds of jobs in various parts of the world that women can't do because they're not allowed to, due to religious or other cultural restrictions - for example, teach boys in Muslim schools.
I'm not sure about female scaffolders, but women are taught how to tile roofs, lay bricks, mix concrete, and so on. Hod-carrying might prove a bit difficult, because we've got to remember that unless we're on anabolic steroids, our muscle groups are different to a man's, although any of us who've lumped wheelbarrowfuls of muck have built up pretty decent biceps! It's no good us wimminfolk saying we can do ANY job, though, if the job is truly beyond the limits of our physique (just as it might be beyond a weakling man's).
It's great, the strides that women have been able to make, even if it took aggressive feminism, stroppiness and bad behaviour to eventually get men to relinquish their attitudes to what women were capable of doing. We now have the equal right to risk our lives in the line of police, armed forces, and fire-fighting duties, to aspire to business-owning (in our OWN names!), training racehorses (ditto!), to drive HGVs, become mechanics, surgeons, dentists, pilots, bus drivers, astronauts, film directors, architects, and all the hundreds of jobs once considered 'unsuitable for a woman'. And what's really great, is that we now don't have to come from extremely wealthy backgrounds to shore up our endeavours, or to be amazingly brilliant. We can now do lots of ordinary, normal jobs which were also denied us due to sex discrimination.
