Polycarbonate good, aluminum bad. Generally the aluminum frames don't hold up to a handful of moderate windstorms.

Palram's products are usually better than the typical Alibaba/Temu/Better Homes and Gardens (I wish I was joking)/random Amazon brand garbage, but we're still talking about aluminum with parts of the structure only held up by tension.

Pressure treated wood and/or steel, at least for the outer frame, unless you live somewhere with virtually no weather.

Aluminum is a great material for this application. If these aren't holding up it is due to poor design in general, and not the material choice. Aluminum won't rust, and lasts much longer outside than a steel structure (if it is designed well).

If you're building it yourself, and milling the aluminum, maybe. But aluminum can be thinned to the point that it's just shy of structural failure, and while Palram's greenhouse structures are not nearly as bad as the cheapest ones, but on the lower end models like this they're... pretty bad. Even if you've got a solid slab foundation (or a good level block foundation around the perimeter) the fit on this is notoriously fiddly, and the aluminum join points will bend, a little at a time, under wind pressure, the vibration of passing trucks or machinery, etc, and eventually, because aluminum is *brittle*, a critical tension element *will* fail. Your weather conditions dictate how long that will take

I reiterate, aluminum is not the material you want for your structural foundation. Too easy to bend, and too brittle where it starts to bend. It's good for the reasons you stated, and in places where you can reinforce it, but you don't want it for pylons, only struts, you don't want cookware that's solid aluminum, and you don't want this aluminum erector set garbage.
