3.6 Decking

3.6m decking boards manufactured to provide a strong, durable, and long-lasting solution for garden decking and outdoor living areas. With a finished size of approximately 120mm in width and 28mm in thickness, these boards are designed to deliver excellent structural strength, slip resistance, and long-term performance in external environments.

Each 3.6 metre decking board 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 effective protection against rot, fungal decay, and insect attack. As a result, the boards are suitable for long-term outdoor use and can be installed in areas exposed to the elements throughout the year.

These decking boards feature a grooved surface profile. The grooves are designed to improve grip underfoot, helping reduce the risk of slipping in wet conditions. This makes grooved decking particularly suitable for areas such as garden seating spaces, pathways, steps, and areas around hot tubs or pools where additional traction is beneficial.

The 120mm width offers a practical balance between coverage and appearance, helping create a clean and uniform deck surface once installed. Wider boards reduce the number of joints across the deck, contributing to a neater overall finish. The 28mm thickness provides excellent rigidity and strength, reducing flex and improving the solid feel of the deck underfoot.

The 3.6m length makes these decking boards ideal for larger decking installations. Longer boards help minimise joins, resulting in a more continuous and professional-looking finish. Where required, boards can be cut to suit bespoke layouts, edges, and design features without compromising strength.

Fully tanalised grooved decking boards are valued for their longevity and reduced maintenance requirements. Unlike untreated timber, pressure-treated boards are protected throughout their entire cross-section. This helps extend the lifespan of the decking, even in damp or shaded garden areas, and reduces the likelihood of premature deterioration.

These boards are suitable for a wide range of domestic and trade applications. They are commonly used for garden decking, raised platforms, seating areas, walkways, and outdoor entertaining spaces. The combination of grooved surface and 28mm thickness makes them suitable for areas that experience regular foot traffic.

When installing grooved decking boards, correct spacing between boards is important to allow for drainage and natural timber movement. Adequate gaps help water run off the surface and prevent moisture build-up between boards. Boards should be fixed securely to a suitable subframe using appropriate exterior-grade decking screws designed for pressure-treated timber.

The grooved profile provides a practical and functional surface, while the natural timber appearance allows the boards to blend seamlessly with a wide range of garden styles. The boards can be left to weather naturally or treated with decking oils or stains if a specific finish is desired. Any additional finishes should be compatible with pressure-treated timber to maintain the effectiveness of the tanalisation.

The 28mm thickness offers a premium feel compared to thinner decking boards. This added depth improves load-bearing capability and reduces bounce when installed on correctly spaced joists. It also contributes to the overall durability and lifespan of the decking installation.

These 3.6m grooved decking boards are suitable for use with timber subframes and can be combined with matching joists, posts, and fixings to create a complete decking system. Their consistent sizing makes planning and installation straightforward for both new builds and refurbishment projects.

Fully tanalised decking boards require minimal ongoing maintenance compared to untreated alternatives. Periodic cleaning and reapplication of protective finishes, where used, will help maintain appearance and performance over time.

This decking option is suitable for both domestic customers and professional installers. It can be used in new garden projects or to refurbish existing decking areas where worn or damaged boards need replacing. Its strength, durability, and slip-resistant surface make it a reliable choice for long-term outdoor use.

The 3.6m grooved decking board measuring 120mm x 28mm provides a dependable solution for outdoor spaces that demand strength, safety, and visual appeal. Its combination of a grooved profile, generous width, solid thickness, and full tanalisation makes it well suited to a wide range of decking applications.

If you are looking for a strong, slip-resistant decking board suitable for garden decking, seating areas, and outdoor living spaces, the 3.6m grooved decking board offers the performance and reliability required for professional-quality results.
