With a light-weight steel shed and a green house, we already have a few wimpy structures that we need to clean off after a snow storm.
I had always said I'd never buy another, but then I did.......
The best light-weight steel structure is a hefty pole barn, built and paid for by someone else.
The next-best light weight steel structure is any one you already have, given the time and hassle of erecting a new one.
That said, in Eastern Ontario winter conditions, we've had much better luck with round-top than straight-top ones like yours.
My inlaws had a straight-top one on their property which worked OK for them for 3 years, with regular snow clearing as suggested above.
Once they moved, they gave it to us. At our off-grid property we're not around to clear snow off, and their straight-top buckled a bit the 1st winter and cracked the 2nd under snow load. It's not the snow itself; it's snow, melting into wet snow, then freezing rain on top, then more snow, that's the problem.
Meanwhile, we have two similar round-tops we got ourselves. To our pleasant surprise, the snow rolls off of them sufficiently that they're going strong, with no snow removal and no damage, after 4 winters.
We have had to replace the included covers with heavy duty tarps, and replace those tarps 2 years later. They just don't do well in full sunlight all year long. But that's a different - and much cheaper - story.
