Hi,
I have a reasonable amount of timber that I collected after removing an internal wall from our 1950s house (we're located in Melbourne). I don't know for sure what type of timber it is, but I expect is a eucalyptus of some sort.
My question is, can i use this for joists on a deck that will be exposed to outside weather conditions (rain and sun) - assuming the dimensions are correct, or is it likely to start rotting within a short period of time.
Cheers,
Luke
#1 What sectional size is it?
#2 If you scratch (firmly) the surface with a nail, does it barely mark it or does it leave a distinct groove?
:whs:
Also: how are they for splits, nail- and/or fixture holes that will collect moisture?
In the past I have successfully re-used old wall studs for decks, if they were both of a size and in good nick. (Successful in the sense that they've lasted this far without needing further attention.)
FWIW I also trim malthoid into long 60mm(ish) strips to run along the tops before affixing reeded decking boards. It's the way I was taught, although I've had blokes think I'm odd in the head and am wasting time and money. Still, I'd rather spend $30 "needlessly" on prevention than not do it and have to pull up the deck for repairs... and malthoid is dirt cheap. ;)
Skew, better product to use now is Protectadeck https://www.bunnings.com.au/our-rang...p/protectadeck
Thanks for the replies. I've hopefully answered the questions raised below.
The timber is 35mm x 95mm although some are closer to 100mm.
If i run a nail along it it just leaves a surface mark, it doesn't gouge it at all.
There's not much in the way of splits, but there are a few nail holes where the plaster board was attached. If i was to used this timber, i would probably use the protectadeck product Ray suggested.
Cherrs,

90 x 35 Hwd seasoned spaced 400mm will span 1200 maximum.
I have run this through a certified structural timber software program and the above result is the maximum allowable spans and spacings.
The results comply with all current relevant codes and standards. Do not exceed these as you will be liable for any failure and subsequent damage or injury.
Thanks Ray, i appreciate your advice
Usually, I use such materials for the construction of outbuildings. This is always needed. The easiest way is to take a reliable project as a basis - https://bisonconstructions.com.au/st...one-dairy-shed I liked this option and I made a shed for poultry based on it.
