Just wanted to see if anyone may be able to help with this.
Large shed lean to. The plan is to fill in the corner with sheeting to protect one side from weather.
8m span between the large poles. Have 5mm steel 100mm post to go halfway, 4m which I have drawn in red. And 120mm top hat to span 4m with sheeting attached.
Dynabolt post to concrete as it's 30mpa and 125mm thick.
Question is.... The top attachment.
I've just realised it's only z channel purlins. I was going to notch out the top post 50mm and bolt it but I'm looking at the channel and the fact it's a purlin makes me wonder if it'll be OK to attach to that and will it hold. I can't brace the pole back in as it'll take up space in the area I need...
Any thoughts?
