Anyone in a snow area have a barn with angle iron trusses? Looking to build one here in Michigan and was looking for information on size and thickness of angle iron, height of truss, and post spacing. I've done quite a bit of work on what size I need for angle iron and design, but wanted to see if anyone had something they could get some measurements off of to confirm my research. Ultimately I know that every building is different so looking at getting it engineered as well, which is the best way.

Code here made me get my plans approved by a structural engineer. He didn't actually charge me that much.
I did take "Strength of Materials" but still.

I am planning to build these myself, not overly complicated for the fabrication and based on some quotes I received and my initial costing I'll save about $2000 for the 9 trusses that I need. Problem is I just need the trusses, I can get all of the other materials cheaper than they can provide it.
Full truss buildings or full red iron frame buildings for the size I am looking to do is $40k, I can come in about $20k for a steel truss building that sits on wood posts.
I'll probably get a local structural engineer to make up the drawings, I don't need to meet code since its agricultural use but I don't want to cheap out either because the equipment beneath is worth well more than the barn.
"Truss me" you want a real structural engineer to make the drawings and do the calculations. They'll know the codes and such too and that PE license prevents any future issues with insurance and such if something bad should happen.
Go with an engineers recommendations. This winter we had a lot of snow collapses around here. Lots of barns and even a local fire department building. NYS code is 80 lbs. per square foot, my town code is 90 lbs. per square foot here in a lake effect zone.
"Angle Iron" trusses? No such thing
Steel buildings are engineered for snow load and wind shear. They come with an architect seal. If you build your own, you are opening up yourself for a bunch of liability and likely installation cost. You will not be saving any money. While your idea seems ok on paper before hand......I think you are dabbling in something that you do not fully understand.
Making your own trusses is a bad idea and should not be done.
