How to Choose Fence Posts. Congratulations on your decision to put in a new fence! Now for some big choices - what kind of fence posts should you use? Here's how to make your way through the mire of options and pick the best kind for your fence.
Determine how much support your fence will need. While there's no point in putting up concrete posts for a chain-link fence, you may be disappointed with the lack of support a flimsy metal post gives your concrete fencing.
Select plastic posts for small or light-duty fences such as picket-style. (Be aware that if the fence will be more than 2 1/2 feet high, you may have to reinforce plastic posts with wooden inserts.)
Pick metal posts (round or square) for chain-link and plastic fences.
Take a good look at wooden post choices. They come in a variety of sizes and types of wood. Pine is cheap and is available in treated forms for outdoor use. Heavier woods, especially hardwoods, look excellent stained and will last a long time, but are much more expensive.
Consider concrete posts. They come in 4-by-4-inch size and vary in height. They're available predrilled for different fence styles - chain-link, panels and rails. These are very solid - and may look odd with some fences.
Keep in mind that concrete and wooden posts can be painted but that they'll require repainting every so often.
