Boards that are maintenance-free for a long time

[spaxx]

which wood/treatment/brand should I choose for a fence that preferably requires no maintenance?

I'm probably going to pour concrete footings and ensure that no wood is in contact with the soil.

Preferably something that blends into nature with more natural colors. Like green, dark, oiled/tarred or similar.

It will be at the property boundary, with a steep drop on the other side.

Pressure-treated is pretty much obvious, right?

Pressure-treated is almost obvious, right?

Yes, absolutely. Are there different qualities?

You can read the classes here and see what might be right for you www.kemi.se/fraga-kemikalieinspektionen/vadinnebar-klassificeringen-m-a-ab-och-b-for-impregnerat-virke/

Cedarwood might work too.. Don't know how common it is or how expensive..

A and AB are what are usually sold in hardware stores. I don't think it matters which you choose for a board:

• Wood impregnated according to class A is intended for use in ground contact and freshwater, as well as in special cases above ground, where there is a significant risk of rot, this corresponds to protection class 4 according to EN 335.
• Wood impregnated according to class AB is intended for use in exposed constructions above ground, such as fences, roof boards this corresponds to protection class 3 according to EN 335.

Check out tar colors, maybe tar vitriol, painted a maximum of 2 times with 1-2 year intervals.

The obvious thing is to protect the fence from rain. Strategically placed metal sheets are more effective than impregnation or any paint.

The upper end grain of the boards must be protected. I myself have a fairly long fence where an angled board clad in copper sheeting provides such protection. The posts have metal caps. The nailers are made of heart pine and are slightly beveled. Everything is painted with distemper. No wood is pressure-treated. It has stood for 12 years now without any changes other than needing a touch-up on the paint. If built correctly, pressure-treated wood is not necessary. Most pressure-treated wood is also planed, which doesn't suit paints like distemper.
