Red steel is a pretty common term in the steel building trade really. Even a square like me knows that.
I didn't buy the Tractor Supply shelter to start an industrial manufacturing business...it's a way to kep the rain and UV rays off my cars temporarily, period. And with a little effort, if there's a wet snow it's just a matter of a few minutes with a broom or roof rake to clean it off.
Maybe you know the climate better than I do here in my own region even after me living here 18 years and plowing snow every day, sometimes twice a day for 6 months out of the year...I might be missing something.
I have a home made shelter here about the same gauge steel and structure that lasted 5 years, never had a problem until 2 winters ago when I decided to remove the center posts that supported the arch. I was trying to park 6 sleds in it and needed the room, but that wasn't a good move. Other than that, the wife doesn't care how much snow piles up on my $^!~, it's all me, all the time, outside.
I wasn't looking for a cocky response to me mentioning that I just bought a Chinese shelter...just made a statement that I did for nothing more than conversation, that's all. If I had more money and time, I'd build a concrete block fort to put my cars in out of the rain and sun...but it ain't happenin' right now.:cool2
