I am planning to fence in the property and am looking to make 2 double gates at a low cost - and without it taking too long - or looking unsightly. Next to the gate posts, there will be a free-growing hedge, so I don't need to worry about matching a fence.

I sketched an idea in the CAD which I would like to get improvement suggestions on: The length of each gate should be 2.0m, the height I'm not entirely sure about - in this drawing, it's 1.0m. I was thinking of using 22x95mm lumber dimensions and then screwing and gluing this together.

To then hang the gate, I am considering attaching a couple of strap hinges, from the side shown in the picture to the left.

- How do you think this will look painted white and finished?
- Now the cross will be under tension (in the blue-colored section) - does this have any practical/aesthetic effect?

If anyone has tips and ideas for other simple constructions, I would be grateful.
 
  • CAD drawing of a rectangular double gate design with X-shaped support centered in blue against a gradient blue background.
  • CAD drawing of a white double gate with an X-brace design. The gate measures 2.0m in length and 1.0m in height, made from 22x95mm wood.
With your lumber dimensions, the gate might possibly feel somewhat flimsy.
That is, sideways.
 
Is it enough to increase to 28x95?
-I thought of another thing - is there any risk that the gate warps, and does it matter how the core side is turned?
(e.g., if the core sides are facing different directions, will the gate twist in different directions?)
 
Make sure to screw the cross together in the middle. You will then increase the stiffness many times over (in the order of 5-10 times, I would guess, without going into a formula collection).

It really depends on what the wood looks like: Slope of grain, knots, etc., increase the risk of it warping.
 
The key is to think in triangles since it is a very strong construction.
Then, you should also remember that it's better to have tensile forces than compressive forces, so make sure to reinforce the upper corner nearest the gate and the lower outer corner significantly.
 
Personally, I would have chosen 45x95 and halved it, as a two-meter gate does get quite a bit of load. Wheels under each gate will probably be needed as well.

I have modified the drawing slightly. I increased the dimension on the upright parts to 45x95 - and if you're going to make notches in those parts anyway, it doesn't take much longer to refine the top a bit.

I sketched in some of the carriage bolts (M8) that I intended as fasteners, in addition to the glue.
-Wheels unfortunately aren't possible due to slopes and unevenness. I appreciate the tips and will start on this once a couple of the other garden projects are finished. These double gates are actually intended as an interim solution until I can install wrought iron gates that match a third already installed gate, but it doesn't matter if the gates last 8-10 years.

If you want the gate to last a long time, you might want to consider using pressure-treated wood.
Personally, I think pressure-treated looks nice!
