Hello,
I'm building a skillion style pergola, using truss anchors through a tile roof.
I plan on using 2 75x75x2.5 rhs posts supporting a 75x125x4 rhs beam at a single span of 5.5m; a 50x150x4 beam on a multi span of 5.5m sitting on roof Extenda stirrups.
I plan on using 75mm insulated trim deck panels spanning 5m.
Wind rating is at the lowest level.
My question is:
are the rhs sizes and plan I have suitable to support a pergola of this size?
