One obvious reason is that the tank support needs to be a material that withstands water, either from small leaks or condensation. Marine ply is designed to survive wet conditions, T&G boards and 'steel plate' are not.

I intended a thick steel plate. It can be galvanised if you like, but my point was another: that to limit to a specific product is needlessly restrictive and that there are numerous materials that would suffice.
I take your point on T&G, if made from spruce. More likely to warp than marine ply too.

I've never seen a steel plate, galvanised or otherwise used in such a manner. Probably because it would cost more than marine ply and be a lot harder to cut and fix.
Anyway, a (the?) key thing about BS documents is that they are specific about materials and methods so that compliance can be verified easily.
