Rough Sawn Timber UC3u Treated Green

admin — Tue, 16 Dec 2025 13:20:31 +0000

These fencing boards are produced from FSC-certified sawn timber, ensuring the wood is responsibly and sustainably sourced. The boards are UC3u pressure treated, making them suitable for above-ground exterior applications such as fencing, decking components, shed bases, and sleepers. For any timber that will be in direct ground contact or submerged, UC4-treated timber is required instead.

“Carcassing” refers to structural softwoods—typically spruce, pine, or fir—used in applications like floors, walls, ceilings, and roofs. This product is supplied as unseasoned timber, meaning it has not been dried to a final moisture level and may experience some natural shrinkage once installed.

All timber supplied carries full chain-of-custody certification for responsible sourcing.

Please note: Timber is a natural material and may vary in color, texture, and grain. Differences in appearance may also occur due to monitor settings. These variations are normal and not considered defects.

Timber Decking UC3u Treated

admin — Tue, 16 Dec 2025 13:20:17 +0000

Timber Decking UC3u Treated Reversible Smooth or Grooved is high quality decking with the option of having it smooth side up or grooved side up for extra grip. Treated Decking provides an excellent alternative to a paved patio area, offering an attractive addition to your garden space that is ideal for al fresco dining and BBQs. Wood naturally rots over time, but by treating the timber, we are able to slow down that process and extending the longevity of the Decking. As a result, treated decking requires less maintaining. All sizes are nominal. Take 5mm off edges for true size. Please note: Timber decking boards may contain naturally occurring knots, which are typical within unprocessed timber products and are not deemed as a fault. Please note: Timber and stone are natural materials, and as such, variation in color, texture, and natural markings is to be expected. We strive to represent our products as accurately as possible through imagery; however, colors and shades may appear differently depending on individual monitor settings such as brightness, temperature, and contrast. These variations are not considered defects.
