This probably sounds thick but where would I go to get an online calc? I've googled and googled but my search terms can't be right cos i'm getting nothing.
Hi All, 1st post and i've been scratching my head on this one.
I'm in the process of building a garage and I need to put a piece of steel across from pine end to pine end to support the roof.
My reasons for using a piece of steel is so that I don't have trusses intruding into the roof...
