• FSC Certified Timber
• Kiln Dried for additional strength and durability

What is 3x2 Treated Timber in mm?

The term "3x2" refers to the joist size in inches, equivalent to 47 x 75mm in metric measurements. However, our 3x2 timber joists undergo regularisation to achieve a uniform size along the entire length, resulting in a "finished" size slightly smaller, approximately 45mm x 70mm.

This slight variation in size generally won't significantly impact the majority of projects and is a standard characteristic across 47x75mm (3x2) timber joists.

What are 3x2 C16 Treated Timber Joists Used For?

Frequently employed in stud walling and partitioning, C16 timber exhibits remarkable strength, ideal for interior construction projects. While it's not advised for supporting the building's structure, its treatment broadens its applicability to diverse outdoor uses such as decking, fencing, sheds, pergolas, and various other outdoor structures.

What Does Kiln Dried Mean?

Timber that undergoes kiln drying is favoured in construction - the controlled conditions inside a kiln facilitate faster and more uniform drying, reducing common risks like warping and cracking, prevalent in air-dried methods. This uniform moisture content notably enhances wood stability and strength.

What Lengths Does 3x2 C16 Timber Joist Come in?

Our selection of 3x2 timber spans different lengths: 2.4m, 3m, 3.6m, 4.2m, and 4.8m. While we aim to have all sizes in stock for prompt delivery, occasional delays or shortages in specific lengths might arise. In such cases, we may substitute longer lengths to ensure timely delivery of your order.

What Does C16 Stand For?

In the UK, timber undergoes grading based on strength and quality, where C16 and C24 are prominent grades. These grades signify the timber's load-bearing capacity, especially under bending stress.

Primarily used for structural purposes, C24 is best suited for higher load-bearing capacity, such as extensive spans or heavier loads, whereas C16, though slightly less robust than C24, remains sturdy and extensively utilised in wall and roofing applications with less demanding load requirements. Both grades ensure reliability, the correct choice depends on structural needs of the project.

Do I Need Treated 3x2 Timber Joists?

Our Treated 3x2 Treated Timber is appropriate for both internal and external applications. In projects susceptible to moisture or pest issues, treated timber may be the preferred choice. Its increased resistance to moisture and pests makes it especially suitable for outdoor projects like decking, roofing, and similar applications.
