Cedar posts or treated pine, which is better??

The question of what type of wood to use always comes up in discussing the longevity of wood fences. The answer is simple, Treated pine posts will last longer than cedar. The problem with using pine is that it is an unstable wood. Lumber industry experts call treated pine " propeller wood".  It will twist and warp over a short time, ruining the look of any wood fence. While it may last longer than Cedar, the twisting and warping will negate that advantage. Sterling Fence Inc. uses western red cedar posts because of this problem. The increased life of the post is not great enough to compensate for the instability of the wood
