Hi Stephen, thanks for info. I know where the factory is, about 15 km from my home but they don't sell retail.
3 meter is ok, I am going to laminate some sections for strength with cut pieces and a left over could be handy for a pier cast one day.
Just need to find a local distributor. Bunnings and the like don't carry it that size. Firth have it but they are way out in the boondocks south of me.
I'll give the factory a ring, see if they can put me onto someone who can supply locally.
