6×6 Post

6×6 gate post manufactured to provide a heavy-duty, durable, and reliable solution for hanging timber gates and supporting structural fencing installations. With a finished size of approximately 150mm x 150mm and a four way weather top, this post is designed for applications where maximum strength, stability, and long-term outdoor performance are required.

Each 6×6 gate post is produced from quality softwood timber and fully pressure treated through a tanalisation process. This treatment allows preservative to penetrate deep into the timber fibres, providing long-lasting protection against rot, fungal decay, and insect attack. As a result, the post is suitable for direct ground contact and long-term outdoor use in a wide range of environments.

The substantial 150mm x 150mm section offers exceptional strength compared to standard fencing posts. This makes the 6×6 post particularly well suited for use as a gate post, where the weight and repeated movement of gates place additional strain on the supporting structure. The increased section size significantly reduces flexing and twisting, helping gates remain aligned and operate smoothly over time.

This post is finished with a four way weather top. The weathered top design helps shed rainwater away from the surface of the post, reducing moisture absorption and minimising the risk of surface splitting or premature deterioration. In addition to improving durability, the weather top provides a neat and professional finish once installed.

6×6 gate posts are commonly used for hanging single and double timber gates, including featheredge gates, shiplap gates, framed gates, and other heavy-duty garden gates. The mass and rigidity of the post help absorb the forces created by opening and closing gates, reducing long-term movement and maintaining consistent alignment.

In addition to gate installations, this 6×6 post can be used at key structural points within fencing systems. It is suitable for use at corners, changes in direction, or areas exposed to higher wind loads where additional strength is required. The square profile provides clean, straight faces, making it easy to fix rails, panels, or gate furniture securely.

Fully tanalised timber posts are valued for their longevity and reduced maintenance requirements. Unlike untreated or surface-treated timber, full pressure treatment protects the post throughout its entire cross-section. This significantly reduces the risk of premature failure, even when the post is installed directly into the ground.

**Pro Tip:** We don’t advise fitting these posts with post mix if you’re hanging gates on them. Post mix simply doesn’t go off strong enough to cope with the weight and repeated movement of gates over time. For gate posts, a traditional concrete mix is strongly recommended to provide a much stronger and more stable footing.

For installation, care should be taken to ensure the post is set to an appropriate depth and positioned perfectly plumb. Correct installation is critical to gate performance and long-term reliability. Taking the time to install the post properly helps prevent common issues such as sagging gates, binding, or uneven gaps.

The natural timber finish allows this post to blend easily with a wide range of fencing and gate styles. It can be left to weather naturally or finished with a suitable exterior paint or stain if a specific appearance is required. Any additional finishes should be compatible with pressure-treated timber to maintain the effectiveness of the tanalisation.

This 6×6 gate post is suitable for both domestic and trade use. It can be used in new gate installations or as a replacement where existing posts are no longer providing adequate support. Its heavy-duty construction makes it a popular choice with contractors, landscapers, and homeowners working on demanding outdoor projects.

The 6×6 gate post with four way weather top provides a dependable solution for installations where strength and stability cannot be compromised. Its combination of a heavy-duty section size, protective weathered top, and full tanalisation makes it ideal for supporting gates and structural fencing in challenging outdoor conditions.

If you are looking for a robust, long-lasting timber post suitable for hanging gates or reinforcing key points within a fencing system, the 6×6 gate post offers the strength, durability, and reliability required for professional-quality installations.
