Hi,I've been extending my self built PD brick shed/garage and I now have a five sided structure with a roof span of over 20 feet at one end.I plan to have a lightweight corrugated steel roof.
I plan to construct an arrangement of joists from steel pallet racking (welded of course) to span the widest part,but am unsure of how to connect to the brickwork but allow for heat expansion,which I'd imagine to be fairly considerable over that length?
