I am building a 9'x9' portable shed with 2 x 6 metal sub-frame. The 3/4" sub-floor is secured by const. adhesive and screws. The 2 x 4 wood frame is secured by bolts through the bottom plate welded to the metal sub-frame. The question I have is how to keep the frameing from moving during on/off loading and transporting? Would blocking alone be adequate or would punched angle be better to tie studs together? Thanks for your help on this topic.
