The 3m Treated Timber King Top Gate Post (150 x 150 x 3000mm UC4) is an industrial-grade, heavy-duty structural post engineered specifically to support large entrance gates, estate gates, and heavy commercial perimeters. Measuring a massive 150mm by 150mm in thickness and standing at an impressive 3 meters in length, this exceptionally robust post provides maximum load-bearing capacity and rigidity. Its substantial profile is specifically designed to counteract the extreme twisting forces and heavy downward weight exerted by wide swinging gates, ensuring the hardware remains secure and operational over decades of use.
 
Manufactured from premium structural softwood, this post features official UC4 (Use Class 4) compliance, certifying it for heavy-duty ground-contact applications. It undergoes an advanced high-pressure preservation process, often enhanced with incising, which allows the protective treatment to penetrate deep into the timber core. This professional-grade defense shields the wood against severe rot, fungal decay, and insect attack, ensuring long-term structural integrity even when deeply embedded in damp, heavy soil.
 
Designed for demanding landscaping and security installations, this 3-meter king post requires deep setting with high-strength post-fix concrete to establish a completely plumb, immovable foundation. The pre-treated green finish naturally weathers to a subtle grey over time, but it can also be painted or stained with exterior wood finishes to match your property's aesthetic. Whether you are hanging a grand driveway entrance or securing a major commercial boundary, this trade-quality gate post delivers uncompromising strength, stability, and long-term outdoor reliability.
