I am planning to build a garden shed. 2.4 mx2.4 m in size. My land is slop. So I decide to raise 9 brick posts, like 3 x 3 layout. I need three bearers and 5 joists. I want to use hard wood. So what size and/or specifications of hard wood I need use for bearers and joists? Thank u Peter Re: What timber I need to use for bearer? 2Sep 15, 2008 3:29 pm 100*75 f8 obhw bearers.
100*38 or 100*50 f8 obhw joists (600 centres) - make sure your flooring can span 600 Peter Clarkson - AusDesign Australia www.ausdesign.com.au This information is intended to provide general information only.

Whereabouts are you? If your not in Vic you won't be using that F8 rubbish Green hardwoods in NSW and Qld are F11 and F14. You really can't recommend a size without knowing the spans first. Re: What timber I need to use for bearer? 6Sep 16, 2008 4:56 pm zaff Pretty sure by this, he means the bearers and joist will both need to span 1.2M in a 2.4x2.4 structure. In that case we just need his location. Timbers from state to state vary that much they might as well be different countries Re: What timber I need to use for bearer? 8Sep 17, 2008 7:48 pm Joists can be F11 75x50 and will be at 61% load capacity.
Bearers can be F11 100x50 and wil be at 43% load capacity. Obviously anything over that size or structual grade will be fine.

90x45MGP10 joists with 90x70 GL8 berarers Re: What timber I need to use for bearer? 13Sep 22, 2008 4:11 pm I have been bunnings. The adviser told me the treated pine is not good for the bearer and joists, he said treated pine is easily twisted. I have a little confused now.
Thank u Luke again. Peter Re: What timber I need to use for bearer? 14Sep 22, 2008 7:27 pm Thats a lot of rubbish - you should know better than to believe someone in a store like that.
If anything its the opposite - the treated pine is kiln dried whilst the sawn hardwood is green (unseasoned) and more likely to shrink and move as it dries out naturally. Re: What timber I need to use for bearer? 15Sep 25, 2008 10:23 am Hi Luke
Thanks for your help first. Original I decide to build a shed at the size of 2.4 x 2.4 m, and I already finished 9 brick posts. I might change my idea. My wife suggest me to buy a metal shed instead of building a wood shed with cement wall. I found there are some online shops that sell zinc shed at size about 3 m x 2.6 m. So It is larger than my post dimension. That means the floor would larger than the post area. So my question is can I install this size of metal shed without changing my posts? If yes, can I still use the timber that you suggested? Best regards Peter Re: What timber I need to use for bearer? 16Sep 25, 2008 7:20 pm I guess you can screw the shed down onto timber framework.
I did a small one at my place like that, I used tretated pine sleepers in the ground in a frame the same size as the shed and then just paved the inside. Re: What timber I need to use for bearer? 18Oct 10, 2008 7:26 pm Hi Duke,
I am going to buy floor for the platform. An expert in bunnings suggested me to buy particle board for the floor. Because my floor(2.4x2.4) is larger than the shed size(2.26x2.26), so part of floor will be out side the shed. In the web site someone has partcle board left in the garden, that only last two years and totally unusable. So I am thinking maybe I need buy plywood and paint it with some oil. Is this all right? Or you have some other better solution? Many thanks. Peter Re: What timber I need to use for bearer? 20Oct 14, 2008 6:49 pm If your going to paint it just use normal CD ply. It uses the same moisture resistant glue as marine ply.
The name marine ply is somewhat misleading in that it is not waterproof but due to its A grade faces is often used in boats etc. All ply is graded with 2 letters from A to D with A being the best. Each letter represents a side of the sheet. Marine ply is simply 'AA' ply, it has the same glue as all other Aust. Standard ply. Its simply a waste of money to use marine ply anywhere if its being painted. Seconded; we just used these last weekend to build a small deck. They worked perfectly as we have bluestone in the area where we wanted to build so digging down was not… 8 9053 Hi Mrboh Just wondering if you have any BAL or flame zone issues on your block, as getting compliance with BAL requirements whilst doing bearers and joists is tough.
