The Snowdon Timber 45 x 145 x 3600mm treated beam is a high-performance structural solution designed for DIY enthusiasts and professionals working on outdoor construction, decking, and landscaping projects. Offering exceptional load-bearing reliability thanks to its C16 grading and pressure-treated finish, it provides long-term resistance against rot and moisture, though users should note that the timber's size requires careful transport planning and potential custom cutting to fit specific project dimensions.

C16 is a structural grade assigned to timber based on its strength, stiffness, and density, ensuring it is suitable for load-bearing applications like floor joists.
Yes, they are pressure-treated for outdoor use, though they are best suited for joists or sleepers rather than direct burial, where longevity can be further improved with a gravel drainage base.
Yes, whenever you cut or drill into pressure-treated wood, you expose untreated inner fibers. You must apply an end-grain preservative to these areas.
Yes, but ensure the timber has had sufficient time to dry out after installation before applying paint or stain.
These beams measure exactly 45mm in thickness and 145mm in width.
Small cracks are common in timber as it dries; however, if cracks exceed 10mm in depth, check the beam's load-bearing integrity or seal with wood filler and preservative.
Store timber flat in a dry, shaded, and ventilated area off the ground before installation to prevent moisture imbalances that lead to warping.
Use only hot-dipped galvanized or stainless steel screws; standard zinc-plated screws will react with the treatment chemicals and corrode rapidly.
When installing, always ensure you have the appropriate fasteners for treated timber, such as stainless steel or high-quality galvanized screws to prevent corrosion. When cutting the beams to length, apply a high-quality timber preservative to the exposed cut end immediately, as this is where the wood is most vulnerable.
These beams are compatible with most standard decking systems and landscaping fasteners. Always check local building codes if using these for primary structural framing of elevated platforms or residential structures.
While the timber is pressure-treated, applying an external wood stain or water repellent every 1-2 years can significantly extend the lifespan of the beam by preventing surface cracking and UV degradation.
