What is the right wedge for a wooden joist to support corrugated roof near 6 mt span next to no focus supports
I am trying to find out if you can get wooden beam that will span a 6mt gap that will support a corrugated roof branch? The weight of the roof is not great, it is built on a 100mmx50mm frame next to 1800mm spacing
Answers: A common practice for long spans is to sandwich two standard 2X8 tembers any length between 1/2" Plywood cut one and the same 8" width using 1/2" dia. bolts and nuts spaced nearly 2' appart to join them together. That'll hold anything you want to put atop of it.
you can span 6m
the subsection you use depends on the load on them so you obligation to know that, also depends on how close the beams are together
also adjectives to add contained by factors such as snow loadings otherwise you may finishing up too close to the roof one day
