Weight of timber

**diy mick** · 15th July 2010, 08:55 PM

Hi everyone. New to this, so hope this works !

I'm building some side gates for my house. I've made the frames from 30mm x 30mm x 3mm Gal. They are approx 1m wide and 2m tall (I need the privacy!). I've clad it with 90mm x 19mm treated pine, which I've painted - I'm happy with how they look. On one side of the house I'll be hinge-ing the gate to a 90 x 90 post which will be dyna-bolted to the brick wall of the garage. The other side will be bolted to a free-standing 90 x 90 post, which I'll be reinforcing by sinking in a 75 x 75 x 3 steel post behind. So, my question is . . Is the weight of the gates going to be too much, especially when it gets wet, or in everyone's experience - will what I'm proposing be sufficient ?
Thanks.

Mick , put a foot on the post .
In fact put two , one at about 6 inches below ground level , and one about the same up from the bottom of the post .
Do you get my drift ?
The top one in the front to stop it leaning in towards the driveway , and the bottom one on the other side to stop the post kicking back.

Thanks Manuka. I'm not too concerned with the post moving forward or back, as this gate will rarely be used but will do as you've recommended anyway. What does worry me is - will the 90 x 90 post be able to support the lateral pull of the gate - even with the steel post supporting it ? (I'm assuming the gate itself weighs about 80-90kgs)

I don't reckon so , its too skinny , and the wrong timber for that job.
Get hold of an old power pole . If they are anything like the ones we have here from over your way , ( we call 'em all 'Aussie hardwood'

it will do the job and you won't need the steel post behind it.
Still use the foot system tho .

Thanks ! What timber would you recommend ? Do you mean bigger (eg. 125 x 125) ?
Also, do you think it would be OK if (like my other gate) I hinge-ed it off a the post attached to a brick wall ?
Appreciate your help on this ???

Do you have a brick wall on both sides of your driveway ? And how solid ( thick , as in how many bricks wide ) is it ? . Of you can attach the post to the solid wall go for it .
A bigger post and a hardwood timber . That gate is a heavy bugga and it will bend lightweight timber at ground level over time.
It might pay to get someone in the know to come round and have a look .

Yeah, there is brick on both sides. The gates are actually for the space between the house and the side fences, so the posts would be bolted directly to the house.

Ah well , if the brickwork is up to it , do that .
