Prefab steel buildings

So not all steel kits are apples to apples.
Like mine actually have engineered trusses.
I know others do , but not all.
Some just use a bender and use the metal to roll over it without purlins.
Those are not very good.
Just because you save money upfront does not mean you save money !
Please do yourself a favor and research the companies in your area !
I fixxed lots of the other companies buildings after heavy snow .
Never have I had a problem with any of the ones I fab.
On the pics I showed I used 2x4 for purlins instead of steel .
That was so I could run them a foot out for eaves.
Plus you also want to find out what the metal panels have for coating ?
There are several different ones.
Gage of the panels 29 and 26 are both standard.
Then the gage of the galvanized framing is important.
Best of luck !
