    Default Cypress Pine span tables.

    I am thinking about building a cubby / fort using Cypress pine. Basically a small square deck of between 1.8 x 1.8m to 2.0 x 2.0m. 4 posts, 2 bearers and 4/5 joists. open sides and a small roof.

    I was going to use span tabels for decking as a guide for joists and bearers. Unfortunalty I loaned my brother in law my copy of Alan Staines. So I have a few questions

    Cypress has a rating of F4?

    Does anyone have span tables for that size? I figure I can go a little lighter as it won't have any great loads.

    (I have tried a search on the forum and google, with no real success for such a small span.)

    Last question would it be cheaper / easier to by premade?

    Default timber promotion council reg's

    G'day Brian, Reg's are as follows for:


    LOW DECKS. Upto 2.0 x 2.0

    F5/F7
    posts: 90x90
    Bearers: 190 x 45 @ 2000c/c
    joists: 120 x 35 @500c/c (450c/c not shown)



    High decks: Upto 2.0 x 2.0

    Posts: 90 x 90
    Bearers: 240 x 45 @ 1900 c/c ( still suits overall span of 2000)
    Joists: 140 x 45 @ 500 c/c (450c/c not shown)

    Make sure that your decking spans 500mm prior to ordering your joists as most boards will only span 450mm.

    Good luck, Jason.

    Jason thanks for that.

    I had a look at a cubby supplier today. 1.8 x 1.8 had 140 x 35 bearers and 70 x 45 joists. They had others that spanned 2.4 with the 140 x 35 bearers.

    I was thinking i could go a little bit lighter than a deck as the potential weight load would be far less.
