8×8 Post

8×8 gate post manufactured to provide an ultra heavy-duty, durable, and reliable solution for hanging very large or heavy timber gates and supporting demanding gate installations. With a finished size of approximately 200mm x 200mm, this post is designed for applications where maximum strength, rigidity, and long-term stability are critical.

Each 8×8 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, even in exposed or high-load environments.

The substantial 200mm x 200mm section represents the highest level of strength commonly used in timber gate posts. This makes the 8×8 post particularly well suited for hanging very large, heavy, or frequently used gates, including wide double driveway gates, bespoke hardwood gates, and premium garden gate installations. The increased mass and rigidity greatly reduce flexing, twisting, and long-term movement caused by gate weight and repeated opening and closing.

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 four way weather top provides a clean and professional finish suitable for high-end domestic and commercial installations.

8×8 gate posts are commonly used for large single or double timber gates where reliability cannot be compromised. Their size and strength make them ideal for wide openings, heavy gate leaves, and installations exposed to high wind loads or frequent use. Where smaller posts may eventually move or fail, an 8×8 post provides long-term peace of mind.

In addition to gate installations, this 8×8 post can be used at key structural points within fencing systems or garden structures where exceptional strength is required. It is suitable for use at corners, load-bearing points, or structural features such as pergolas or entrance structures where a substantial timber post is needed. The square profile provides clean faces for fixing hinges, gate furniture, rails, or structural components 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 and subjected to constant moisture and movement.

**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 8×8 gate posts, a traditional concrete mix is strongly recommended to provide a much stronger and more stable footing capable of supporting very heavy gates long term.

For installation, care should be taken to ensure the post is set to an appropriate depth and positioned perfectly plumb. Due to the size and weight of an 8×8 post, correct installation is essential. A well-installed post will help prevent issues such as sagging gates, misalignment, binding, or uneven gaps developing over time.

The natural timber finish allows this post to blend easily with a wide range of gate and fencing 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 8×8 gate post is suitable for both domestic and trade use. It is commonly selected by contractors, landscapers, and customers undertaking premium or heavy-duty gate installations where long-term reliability is essential. Its size and strength make it the go-to choice for the most demanding gate projects.

The 8×8 gate post with four way weather top provides a dependable solution for installations where maximum strength and stability are required. Its combination of a very heavy-duty section size, protective weathered top, and full tanalisation makes it the strongest timber gate post option available for garden and boundary applications.

If you are looking for a robust, long-lasting timber post capable of supporting very large or heavy gates, the 8×8 gate post offers the strength, durability, and reliability required for professional-quality and high-end installations.
