I would like to get aluminium ones but a alu u channel on its own wont be strong enough.
I saw some suitable ones on some or other youtube vid for putting a inflatables floor in that would work and was made completely of aluminium. Gonna try avon and see what they say, if no luck with them might manufacture my own for now. cheers
