FENCE POSTS
The two most common types of fence post are made from concrete or wood, both are usually around 100mm / 4″ square and come in various lengths.
Concrete posts are very strong and resistant to inclement weather, but they also tend to be a little more expensive than wood posts and depending on their length can be very heavy and you will probably require help when manoeuvring them into position (see concrete fence posts). They can be painted with masonry paint rather than just having the plain concrete finish.
Wooden posts should always be pretreated with a good quality wood preserve, treated hardwood posts offer the greatest resistance against inclement weather and damp conditions. They are obviously lighter than concrete and therefore easier to position (see wood fence posts). Most wood preserves come in a variety of colours and therefore the post colour can match the fence panels etc.
