Rustic Oak Square Fence Posts, Hardwood, 1.8m to 3.0m, 75mm or 100mm Square

These rustic oak square fence posts are solid oak hardwood posts with a square section, sold individually. They suit garden, estate and countryside fencing where a natural timber look is wanted, as well as landscaping and decorative work. Two sections are offered: 75mm × 75mm in 1.8m and 2.4m lengths, and 100mm × 100mm in 1.8m, 2.4m and 3.0m lengths. All five sizes are currently available. They suit gardeners, landowners, landscapers and fencing contractors.

Why it works

Oak hardwood with a rustic look

Oak is a dense hardwood. These posts have a square section and a rustic character, which suits informal garden fencing, countryside boundaries and features where the timber is meant to be seen rather than hidden.

Naturally durable without pressure treatment

As a general rule, oak is a naturally durable hardwood and is not normally pressure treated. Its resistance to decay comes from the timber itself rather than from an applied preservative. The durability class for this line is not published, and neither is whether the posts are supplied green or seasoned.

Weathers to silver grey

Left outdoors without a coating, oak generally weathers from its fresh colour to a silver grey over time. Many people choose oak for this reason, as weathered posts sit comfortably alongside gardens, hedgerows and field boundaries.

Know the limits: checking and fixings

Oak commonly checks, meaning small surface splits open along the grain as the timber dries and moves. This is a normal characteristic of oak. Oak also contains tannins, which can stain and corrode unprotected steel and can leave dark marks around fixings. Use galvanised or stainless steel fixings throughout. The finish, weight and whether the posts are pointed are not published for this line, so check the posts on arrival if your installation method depends on any of these.

Specifications

Choosing the right option

There are two choices to make: the section and the length.

75mm × 75mm is the lighter section. In general practice it is used for garden fencing, post and wire fencing, rustic and decorative fencing, and raised bed corners. It is available in 1.8m and 2.4m lengths.

100mm × 100mm is the heavier section. It is generally the better choice for post and rail fencing, heavier fences and features such as pergolas and arbours. It is available in 1.8m, 2.4m and 3.0m lengths.

To choose a length, work back from the height you need above ground. A common rule is to bury about a third of the post. On that basis, a 1.8m post leaves about 1.2m above ground, a 2.4m post about 1.6m and a 3.0m post about 2.0m. Ground conditions, exposure and the load on the fence may call for more depth, so allow for your own site.

Installation, use & care

Mark out the fence line and post positions first. Set each post with about a third of its length in the ground, either in concrete or in compacted hardcore. Where the ground is suitable, posts can be driven instead; as whether the posts are pointed is not published for this line, check them on arrival before planning to drive. Keep each post plumb while it is being set, and check the line before any concrete hardens.

Use galvanised or stainless steel nails, screws, staples and brackets, as oak tannins can stain and corrode unprotected steel. Expect some surface checking as the timber dries; this is normal for oak. Inspect the posts and fixings from time to time, and replace any fixing that shows signs of corrosion.

FAQ

Are these posts pressure treated?

Treatment is not published for this line. As a general point, oak is a naturally durable hardwood and is not normally pressure treated.

What fixings should I use with oak?

Use galvanised or stainless steel fixings. Oak contains tannins that can stain and corrode unprotected steel, which can mark the timber and weaken the fixing over time.

How much of the post should go in the ground?

A common rule is about a third of the length. For example, a 1.8m post set this way leaves about 1.2m above ground. Set it in concrete or compacted hardcore, or drive it where the ground is suitable.

Will the posts split or change colour?

Oak may check, meaning small surface splits form as the timber dries. This is normal for oak. Left uncoated outdoors, oak generally weathers to a silver grey over time.
