8x2 Treated Timber C16/C24 47x200mm (Pack of 55) – 3.6m

Save even more with our pack of 55 pieces of 8x2 treated timber joists, ideal for use in structural framing, as joists and beams, and a variety of other uses due to it’s strength grading. Our 8x2 timber is kiln-dried for straightness and strength, and are regularised to achieve an even and smooth finish. This timber is approx 45mm x 195mm when finished.

• Available in 2.4m, 3.6m & 4.8m lengths.
• High-pressure treated (to UC3/UC2 standards or equivalent, using modern preservatives like Tanalith E or similar) – provides long-lasting resistance to fungal decay, insect attack, and weathering, making it ideal for both indoor and outdoor applications (above ground contact).
• Kiln-dried – reduces moisture content for greater dimensional stability, reduced warping/twisting, and enhanced overall strength and durability.
• Regularised with eased corners – smooth, consistent finish that's safer and more comfortable to work with; minimises splinters, improves paint/stain adhesion, and gives a neater appearance.
• Lightweight yet strong – C16 or C24 graded for structural uses.

For proper installation, use exterior-rated fixings and hangers compatible with treated timber, re-seal all cut ends and notches with an appropriate end-grain sealer, and ensure the timber is only used in dry internal or covered external locations above ground.

Important: Finished dimensions are typically slightly under nominal sizes approximately 2mm less in thickness and 5mm less in width. Always seal cut ends and notches with a suitable end-grain sealant.
