What timber for decking posts?

[RebeccaMW]

Hello, needing some help. What structural decking posts are suitable?

Are these suitable for building a deck? If not, what are the recommended posts to use?

100 x 100mm 2.4m Post H4 Treated Pine Sawn CCA - 2.4m

Hello @RebeccaMW 

Welcome to the Bunnings Workshop community. It's sensational to have you join us, and thanks for sharing your question about decking posts.

The 100 x 100mm 2.4m Post H4 Treated Pine Sawn CCA - 2.4m are designed solely for landscaping projects and do not carry a structural rating, meaning they are not suitable for supporting deck structures. For decking, the correct choice would be the 90 x 90mm 3.0m Post F7 H4 Treated Pine Premium KD, which is structurally graded and approved for such applications.

If you need further assistance, please let us know.
