When purchasing fence panels you will also need to buy posts, the two most commonly used are concrete and timber.
Concrete posts are made using four internal steel reinforcing bars and then moulded in concrete. They cannot rot as the material is not degradable. Concrete is stronger and heavier so it can withstand high winds. Installation process is much more difficult than wood due to size and weight.
Timber posts on the other hand come pressure treated but over time will endure insect attack and rot. They are half the weight of concrete posts and easily maneuverable. Timber posts have a more aesthetic look as it blends in with the timber fences and allows the fences to be more secure by screwing them into posts.
