I hope to be putting up a building sometime in the next year, around 30' x 40' or maybe bigger even. (I want bigger, funds are always scarce though) I'm pretty familiar with traditional pole barns as there are many around here, but I haven't seen many quonset huts to check out. Steel Master makes a couple of models with straight walls, so the arched walls aren't an issue. Steel Master seems to be competitively priced but I fear that maybe there's some vital thing not included in their pricing lists or something, since I've never dealt with them and there are no local reps, it's worrisome. Main use will be as a shop for my bikes, truck, etc and I'll also have a lathe and mill in there and some day I'd love to install a 2 post lift. I want room to separate the metal working stuff from the vehicles and still have room to work in either space. Just curious if anyone has experience with both and pro/con of them.
