ᐅ Building Stair Railings with Aerated Concrete Blocks – Is It Stable?

Basically, you are right. But it’s not that unlikely over the years for a "sufficient" impact to be transferred to the wall. Bumping into it with a heavy piece of furniture can be enough. Therefore, it seems sensible to me to at least fasten a mounting profile or something similar to the free end of the staircase and include it in the purchase. It doesn’t really cost "anything."

Yes, it wouldn’t hurt, that’s true! It should also be something one can do themselves.

Your stair railing is really great. We are also getting a double half-turn staircase with a relatively small stairwell opening, so the varying riser heights are quite a challenge. Initially, we even wanted a wooden handrail, but that would require working with such offsets. We are still in the planning phase at the moment, but I haven’t found a really good solution for that yet. In my 3D model, I assembled the railing from different blocks, which is why it looks a bit odd.

Could you possibly share one or two more pictures of a railing? That would be really helpful.

Works well with drywall too. Profiles were screwed from the side into the concrete staircase. The drywall was then filled, sanded, and finished with a fine plaster coat.
And yes, it gets very dirty easily. That’s why oak will be installed on top in the next few days.

Since the thread has been reopened, I’ll go ahead and write something here as well.

We are also considering how to design the railing. Initially, a glass panel was planned, but that is somewhat expensive... We want it to be as narrow as possible, and a steel railing is also quite costly. With drywall construction, we are concerned it might not be stable enough. But apparently, it can work.
@ivenh0 how thin is the railing and the staircase itself?

We have exactly the same staircase, but our gap in the middle is a bit smaller, about 1–2cm (0.4–0.8 inches)... I’m not sure if profiles can be attached there, so we might have to build a masonry wall. The staircase is 110cm (43 inches) minus the railing, plus plaster, which leaves us with only about 100cm (39 inches). We would like it to be as wide as possible. What other alternatives are there?

The profiles are U-profiles with a thickness of 3-4cm (1.2-1.6 inches). However, this won’t be cheaper than a steel railing. After the drywall work, corner beads are installed, followed by plastering, sanding, plastering, sanding again, and then the desired paint or textured coating is applied.
The railing is only as strong as the underlying structure; in our case, no compromises were made on the profiles...
So it definitely works.
