Thread: Pergola Timber

A mate of mine used dressed Oregon which come up great. I think it was done in a cedar type colour.

You can get kiln dried H3 treated radiata that's not CCA. I wouldn't use untreated pine unless you plan on putting a roof on it to protect it.

We had an oregon pergola outside, dry rot after 6-8 years. Easy to work by in my opinion does not have the durability for external use.
Maybe hardwood or dressed TP

I wouldn't use oregon unless it is covered, it will last about 5 years then it will soak up water like a sponge and rot very quickly. Hardwood is the best for exposed situations.

My timber supplier laughed at me when I mentioned Oregon. He advised against it because it is prone to rot.

I have been quoted on Treated Pine F7 CCA H3 and F17KDHW.The KDHW was a little bit more expensive. Can anyone suggest a suitable hardwood which is of reasonable price? Another option is Cypress Pine?

A similar problem with hardwood.

they're around

If you go the F17, ensure it is Durability Class 1 to ensure it is suitable for your exposed application - not all are.

Thanks not too keen on F17, there is lots of gum vein and checking. But what other hardwood options do I have at a reasonable price?

Andy, nothing beats TP for price, hardwood is heavier, more difficult to work and will cost probably three times as much. Why not stain the TP, you probably would be pushed to tell the difference.
