My buddies garage is a lot like Ben’s…. Has the beams for the main structure.@Buckmaster hey Ben you need to weigh in here and educate Jamesey on the features and benefits of steel....maybe show him some pictures of your barn...and you live up there not far from, so a Northern Ohio perspective...
@CJD3 you needz to talk to Ben
I think i miss understood your original question. My building is a pole barn. I consider it wood framed. I think you were talking about 2x4 like your existing building. The more I think about this the more I like replacing it the same. Sure you have to paint it but it matches the house. Unless you are trying to get away from the maintenance?
Most popular and economical is 29 gauge. If you want heavier than go with 26 gauge.Need to find out what gauge steel they use.
The engineer I work for does lots of steel building plans and they are ok. There is nothing wrong with them, if and this is the biggie, they are designed and built correctly. I would make sure they are sealed by a structural engineer, maybe even call a local structural engineer and see who they do work for.
if you have the concrete pad that they use and bolt the new building down to then this is definitely the cheaper way to go.
