when ASSA built our the new turret at Stockport, we used a steel rack which is 7mm thick and mode 8 tooth spacing. Using plastic or cast racks will not survive if the load of the roof is too high. I suspect your roof is very heavy as the shutter on our roof is 400kg and it is flat, 5 metres long and only 2 metres wide. The rack we used was the minimum calculated by our engineer to bear that load.
I am sure you will get this sorted but thick steel is the way to go in this instance. You can get them cut via engineering firms which laser and computer cutting.

thanks Paul hopefully the builder will get it right eventually
I google map'd your location, how do you go with direct light from your neighbours and the town you are in? I have one neighbour who when I built my Obs thought it a good idea to install multiple flood lights.
A couple of general comments, great to see your builder / concretor knew how to place the plastic under the slab, most do it wrong and carry it up the inner side of the formwork.
The idea of it being " overbuilt " is often brought up, I don't want to live next to a structure that could blow away in a stiff breeze and I don't want to be in one when the thing is blown over nor do I want to be thing about repairs to the slab because it failed or the walls failed when the roof opened. Yours " looks " overbuilt but it looks right to me.
Also happy you got the roof sorted, I had a few early problems with mine and was always worried it would open then decide to stop when I was finished.
Hi Jen
Oh dear we can only dream of what you are doing .Can't wait to see the finish result ,and as far for the first engineer, lets hope the back wheels fall if his car one day
