Wet sawn refers to sawn timber that has not been processed any further. It is fresh from the saw.
Kiln dried refers to the same timber after it has been spaced out with dolly sticks, placed in a kiln and dried (moisture removed) which, in simple terms, makes it more stable for use.
Dressed means it has been machined to remove the rough saw marks giving a smoother surface.

Wet sawn will be cheapest and as further processing is done (kiln drying and dressing) the value of the timber increases.

Thank you so much for that.

So for use in the outdoors (retaining wall ect), It should be kiln dried dressed? Is this correct?

No way. For non-engineered (small) retaining walls you should use treated pine minimum H3 treatment or class1 hardwood if you must. Both used roughsawn.
For walls needing an engineer, you use what they tell you

rought sawn timber can and usualy dose cup, bow twist and split.

air dryed timber has already doen this and the seller threw away all the bad bits or resawed it.

kiln dryed timber has been dryed quickly in large stacks that reduces the cup, bow, twist that you get increasing the amount of useable timber but it isnt cheap to run a kiln.

dressed timber has been run threw a planning machine to produce flat smoth timber.

One way to look at it is: Wet Sawn is firewood. It may be in big pieces, but it's still just firewood.

Everything else is just the more select pieces picked out of the firewood pile and processed further. (Nowadays, with quality woods becoming scarcer, more & more is being picked out and less "junk" being left behind. What used to be deemed fit only for pulp-mills is being used for building houses! )

For garden edging, etc. wet sawn is fine... provided you don't expect it to last for years. For anything structural, including retaining walls, you want better quality.

you can buy top grade furniture timber rough sawn mutch cheeper than dressed and its still just as good. it just needs a little work.

I was speaking in general.

As for grading, you're right. But in my experience wet sawn has rarely been graded. It's a "you get what you get" type of thing.

That's one of the differences between selling timbers as rough sawn and as wet sawn. (Or it was when I was a kid, anyway.)

[weisyboy]

depends where u come from i guess.

wet sawn and rough sawn are more common than not teh same thing. where dry rough sawn is dry. unless a grade is listed (ie: select grade) than u get what you are given. you can however buy select grade rough sawn wet timber.

if u are planing on making anyhting in teh next 12 mounths then buy seasoned wheather it be kiln or air. if u have space and time then buy green and u will end up saving a fortune.

weisy is right. Wet sawn (aka rough sawn or green off saw) has nothing to do with the grade of the timber. You can get Class 1 top quality wet sawn timber ready to go. It is not firewood.
Though wet sawn it is given a strength grading and is often used in structural framing.

It sounds like Melbournechris is after something for landscaping. If so you can use a treated timber suitable for ground contact or untreated timber that is durable when in contact with the ground. eg tallowood, grey ironbark, etc.

Thanks to all...

Steve, you are spot on. I am building a retaining wall with treated pine posts and plinth....150X25. Bunnings has got 5.4m lengths for $8:75..... It is not going to be seen as I am then going to put on Blueboard, then a render......So, keep the ideas coming.


Reagrds,

what is the wall retaining.

25mm is not strong enough to support weight of soil or rock.

[Melbournechris]

It is going to be a 600mm high retaining wall using prob 4X150mm treated pine, but to answer your question only 300mm is just earth soil and the rest will be a garden bed soil....

You need to use 3 x 200 x 50 H3 pine sleepers

Cheers

[weisyboy]

you need to use 50mm thick sleepers.

you can buy 200mm x 50mm x 2.4m sleepers for $13 at bunnings here in brisbane they are the best bet for your application.

you will not be able to buy kiln dryed dressed treated pine.
