Hey guys
The missus is pushing me to builder her an open air (no roof ) pergola to grow some grapes over.
This would join to the existing pergola. She wants it 7M by 6M with no supports in the middle. Now I know that is a damn long span, but as there is no roof three 150X50 3.0mm gal hunks of steel (three – one on ether end and one in the middle) then running a 40X40 2.5mm diagonally every 1 meter for the vines to grow..
Do you think the 150X50 will support that span?
I have attached a rough diagram to explain
cheers
