Save more with this bulk pack of 121 pieces at a better per-unit price. Our 4x2 treated timber joists 47x100mm in size (finished size approx. 45x95mm) are made from high quality, responsibly sourced timber. Each 4x2 treated timber length is kiln dried for straightness and strength and treated for resistance to moisture and pests. 

• 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.

Please note: This product is not suitable for direct ground contact. Fixings with nails, screws, or adhesive are recommended.
