Exactly right.
This particular one is suitable for me (right size), the only problem is there is no connectors, so the building is somewhat complicated.. it can be organised, though - there are 3 variety of spokes, that can be manufactured separately.
The cover plates (Al or galvanised steel) will add to the structural strength of the whole thing.
I am thinking along those lines because of relatively high price of the commercially available domes (like Sirius or Kiwi domes - they are ~10k for 2.3m diameter), and this is not all - you still have to have the building to mount the dome on.
That is why Astro Dome is interesting: very little else is required for the observatory, see here:

But, as I mentioned earlier, it is not available at the moment
