jjcarroll1 - 4/28/2019 20:08 I've got 20"x30' ft long ijoists going to be used for a lean to I'll be building. Question is beings they're so heavy duty how far apart can I place them? I'll be using them as rafters but thinking 24" on center would be overkill beings it'll only be holding the tin on the roof. Strictly cold storage area. Thanks
Maybe call these guys and ask some general questions related to their I-lam roof truss . . . . . You don't mention your area and types of roof loads and wind loads ? ? ?
This past winter, I'm sure there are many guys (whos sheds went down), wish they had truss's closer together.
