Are round fence posts treated?
Yes. Our machine-round fence posts have been green pressure treated to ensure longevity when exposed to the elements outside. We also supply UC4 round fence posts which have undergone a more vigorous and penetrative treatment, as well as cundy peel posts and creosote posts for professional applications. You can find out more about our treatments here.
Are round posts stronger than square posts?
There is little difference in strength between round posts and square posts, but they are used for different purposes. For example, whilst square posts tend to have a more stable base, round posts are most commonly used for animal enclosures and animal prevention as the sharp corners of square posts can rub against wire fencing and cause the wire to deteriorate.
For increased strength where large animals are being contained, we recommend opting for cundy peel posts. Cundy peel fence posts are stronger than both square and machine-round fence posts as the natural shape of the timber has not been altered as much.
What diameter should a fence post hole be?
Round fence post holes are recommended to have a diameter 2-3 times the width of the post, for example, a 12 inch hole for a 4 inch fence post. The depth of the post hole should generally be one-third to one-half of the posts height above ground, for example, a 6ft post should have a depth of at least 2 feet. However, the deeper the post holes, the more stability your fence has. With a 4-way pointed base for easy installation, our round fence posts can be rammed into soft ground.
Should fence posts be set in concrete?
Round fence posts are generally installed straight into the ground, taking advantage of the 4-way pointed base. When installing pressure treated fence posts, the concrete should ideally be poured around the post as opposed to underneath to extend its overall lifespan.
