Fence Posts Tips and Advice

A fence system normally requires two different types of posts: corner posts, used where greater tension occurs in the fence line, such as corners and gates; and line posts, used to support the fence wire between corners. Post selection depends on the type of fence and the expected fence life. Don't worry about spacing posts evenly. On level terrain they can be further apart; on uneven terrain, posts should be placed wherever there is a high or low spot. On hillsides, posts should be installed perpendicular to the slope. This keeps the wire at the proper height and spacing and prevents it from binding on insulators or clips. Post spacing will also vary depending on the animal being controlled and the type of fence wire used. Electric fencing typically uses fewer posts than conventional barbed or stock fencing, making it less expensive and easier to install. The type of post selected also determines the type of insulator required. Refer to the following Post Selection Guide to determine what posts work best in your situation.  Post Selection Guide Portable Fencing Strip grazing - for dairy cattle. For single wire use, either metal pigtail posts (19-196) or poly posts, either (19-197 or 19-297). Strip grazing - for sheep. Use poly posts, either 19-197 or 19-297. Alternatively, consider a complete 3 reel system consisting of 3 wires for either 400 metres or 500 metres long. (19-199 or 19-200). Temporary Fencing Fences that are moved once or twice per year. For corners and fence ends, use either wooden posts with insulators, typically 15-129, or metal mounting stands with reels for the fence end, 19-192B or similar, and metal termination posts, 19-193 for corners. Permanent Fencing For a very cost effective system on long, multi-wire fences use softwood posts for strainers and line posts together with insulators. When using high tensile steel wire always use high specification line insulators such as 15-124 and 16-122 for strainers and corners. Corner Posts Corner posts and strainers should be very firmly installed and be typically as far in the ground as the top wire is high with breast logs or brace bars for maximum stability.
