This 3.0m x 100mm x 100mm wooden fence post is designed for fencing jobs that need maximum length and a strong section. It is a good option for tall fencing, deep setting in softer ground, or sites where wind exposure means you want extra post below ground. The 100mm square profile provides a solid fixing face and a stable feel once installed. It is pressure treated and finished in brown for outdoor use.
At 3.0m long, this post gives you plenty of scope to set deeper and build higher. As a practical guide, plan to bury at least a third of the length, and consider more if the fence line is exposed or the soil is not firm. Deep, well-supported posts help reduce rocking, which is often what causes fences to lean over time.
Good preparation makes a big difference with longer posts. Set out the run with a line, mark your bay widths, and plan where corners and ends sit before you dig. When fitting, check for plumb as you go and keep the post steady while you pack or concrete. If using concrete, allow enough space around the post for a strong collar and finish it so it slopes away from the timber for better water run-off.
The 100mm section is suited to timber fence panels and heavier framing where you need reliable fixing. It is also a sensible choice for corners and returns where the fence line changes direction and the post takes more strain. For gate hanging, you would usually choose a dedicated gate post size, but for panel runs this is a robust option.
If you cut the post down, treat the cut end grain before installation. For a smarter base and to help keep panels clear of ground moisture, gravel boards are often used. Choosing suitable cement products for your ground and installation method will help you achieve a straight fence line that stays put.
