Pressure Treated 4×2 Timber

Our sawn treated 4×2 timber is one of the most popular and versatile structural timber sizes used in outdoor construction projects. Finished to approximately 100mm x 48mm, this rough sawn timber offers strength, reliability, and excellent performance where durability really matters, perfect for those jobs when you need something a bit more heavy duty than our 3×2 timber.

Pressure treated for enhanced resistance against rot, decay, and insect attack, this 4×2 timber is ideally suited for external use. The treatment helps extend the lifespan of the timber even when exposed to the elements, making it a dependable choice for long-term outdoor applications.

Thanks to its robust dimensions and adaptable nature, this timber is widely used for building sheds and outdoor buildings, pergolas, fencing rails, decking frames, and many other DIY or trade projects. The rough sawn finish provides a more cost effective, traditional, rustic appearance while maintaining solid structural integrity.
