6x2 Treated Timber C24 Regularised Sawn Joist 47x150mm - 3.0m

6x2 Timber is most typically used as framing and structural timber. It’s high strength grading (c24) makes it ideal for building stud walls and partitions, as well as in roofing and flooring joists. With some additional treatment or the use of moisture-resistant membranes, our 6x2 timber is also ideal for building decking as it’s high strength makes it supportive enough to hold considerable weight. 

We sell two of the most popular types of 6x2 timber - a sturdy graded C24 timber either treated or untreated. Both are typically used for framing and structural purposes, with the nly difference being that one is graded for some moderate resistance to moisture and pests. 

In the UK, regularised timber is most commonly classified into two grades: C16 or C24. The "C" signifies the wood type, specifically Conifer. The number (24/16) indicates the bend strength - which is based on factors such as imperfections and knots. While C24 is the stronger grade, C16 remains exceptionally strong and is used in numerous wall and roofing applications.

If you are confused about timber sizing, this explanation should help: “6x2” refers to the traditional way of measuring timber - in inches. In millimetres, this roughly translates to 47x150mm. However, as our structural timber is regularised - a process where a length of timber is planed to achieve a uniform finish - in reality the dimensions are typically a few mm smaller than that - more like 45mm x 145mm. 

Our Treated 6x2 Timber is treated to UC2 for resistance to moisture and pests and can be used in outdoor construction - though timber in direct contact with moisture may need further treatment.
