What Are Fence Posts?
Fence posts are the upright supports that hold fence panels or rails firmly in the ground. They form the basic frame that keeps fences standing straight and steady over time. Made from timber, concrete, or metal, boundary posts are built to cope with weather conditions like wind, rain, moisture and shifting soil. Whether for home, farm or business use, fencing posts are key to a fence’s overall strength and lifespan.
