Redwood is the usual pine species you see in every timber merchant's.

I hadn't realised that. I naively thought that redwood was another
species, redder in colour than pine!

Problem is, it comes in a variety of grades, depending where it's grown,
and the retail punter is not party to that information. Terms like
"professional grade" or "joinery quality" mean sod all really

Yes, I had realised that "professional quality" labels were just for
marketing purposes.

In the timber brochure I was sent it talks about grade. the options
are "unsorted", "fifth", and "sixth". I am guessing that unsorted is
what it says and could be good or could be bad all mixed together but
what is fifth and sixth (and where are first to fourth)?

Thanks.

That has never made sense to me either, and I used to buy softwood by
the pack (around 4 cubic metres). A Finnish 5th is better than a Lower
Gulf unsorted, and Russian Karasea is the creme de la creme. Welsh
redwood is used for pallets. The further north it's grown, the higher
the price

"Timber / Lumber can be graded in to I, II, III, IV, V, VI, if they
where in the 21st century 1, 2, 3, 4, 5, 6. However in the jargon of the
timber world, instead of saying “grade five” it’s “fifths” or written as
“V” etc.

OK.. got that, on to the next jargon.

Grades I, II and III aren’t actually graded, it’s the IV V VI that are
given grades. The first three grades are all lumped together and called
“Unsorted” “U/S”. I should think there's a commercial reason for this to
the benefit of timber suppliers."
