That doesn't make it untrue.

Marketing is mostly about telling the truth in an inventive way.

That's brilliant: many thanks!

So, basically, posts in, frame round them in 6x2 fixed using coach screws, joists across the frame in 6x2 fixed using coach screws through the frame into the ends of the joists, boards down and fixed using decking screws, open beer...

That's OK then 'cos I'm a slow DIYer. ;o)

Management has 'been thinking' (you may have heard the phrase?) that 2M square might do it. Would I still need 6x2 joists, or would 4x2 be adequate?

Apologies for having to come back!

4 x 2 will span 2 metres no problem.

Open beer being important bit :-)

Od BCO rule of thumb for floor joists (which was very close to the span tables) was floor joists will span [feet] half the depth [inches] -1. Decks are slightly less critical as there's no plaster ceiling to crack and you're unlike to load them with bookcases and the like.

Can't work that one out Tony.

If I've understood, a 6x2 for example. Depth 6", half that = 3", -1 = 2 feet.

According to Table A a 6 x 2 will span 3.06m at 400mm centres?

Sorry having a senior moment! 2 x (D-1) - so 6x2 spans 10 ft.

To get the size you halve the span and add 1.

Ah - thats better. handy little rule of thumb - ta.
