How to choose posts for boundary paling fence?

Building a boundary Pailing fence. 
looking at either wooden or galvanised steel posts. After suggestions. 
1.8m high fence with staggered step down due to slope so will need posts longer then 2.4. What would you recommend.

Re: posts for boundary fence

Hello @Ryan1980 

Personally I would go with Gal steel - lasts longer.

But, wood is easier to work with.

 

How long is the fence?

Cheers.

15m long. Yeh I reckon galvanised steel the best.

Re: posts for boundary fence

Hi @Ryan1980,

 

Wooden posts offer a natural look and are relatively easy to install. For durability, choose treated H4 pine or hardwood. Galvanised steel posts are sturdy and long-lasting, providing excellent support for taller and heavier fences. They require less maintenance and resist weathering, pests, and rot.

Since your fence is 1.8m high, for stability, consider posts around 2.7m to 3m or longer for steeper slopes. Choosing suitable materials, such as gal posts specifically designed for fence posts, is also important. If you use a thin-walled post, you could see it rusting out much faster than H4 timber would deteriorate.

 

Let us know if you have any questions.

Re: posts for boundary fence

That would work, @Ryan1980. It is a milled smooth post, and you won't find rails that are not rougher header. It would be used if you were going to pair it with 90 x 42mm 3.6m F7 H3 Treated Pine Primed LOSP and paint the fence. Typically, you'd pair 90 x 90mm 3.0m Post F7 H4 Treated Pine Premium KD with 90 x 45mm H3 for the rails.

Here's a helpful step-by-step guide @Ryan1980: How to build a fence. They don't mention the spacing in the guide, but typically it would be around 2700mm.
