The Sheng Li, which looks just like the thing I'm looking for is
actually the cheapest. 14 quid per square metre, just like the B&Q
stuff. I'll probably go along and compare with the other shades,
though. I can't get much of a feel for the stuff from a web site.

The Sheng Li is also wear rated for 6 (heavy interior/exterior
commercial use) rather than 3 (moderate interior/exterior domestic
use) for the bamboo. The large colour variation is an advantage.

Actually I hadn't noticed that, that would suggest that the Sheng Li is a
much stronger slate, you may get away with thinner / no ply?, certainly one
to ask them.
