Treated Timber

Learn more about treated timber

Our range of treated timber is ideal for external construction where improved durability is needed. Within the collection of products that we have available, you can source practical section sizes and lengths for framing, fencing support and general outdoor building work. For an accurate selection, use product specifications to confirm finished dimensions, timber grade and treatment suitability before ordering.

 

Typical uses

 

• External framing and carcassing, where treated sections are specified.

• Fencing builds using compatible components from our fence posts range.

• Landscaping structures, which may also require products from our timber sleepers category.

• General timber jobs that connect with broader sawn timber requirements.

• Stud and framing work, where CLS studwork timber is also being specified.

 

How to choose the right treated timber

 

• Match section size to load, span and fixing method.

• Check finished dimensions rather than nominal size references alone.

• Confirm treatment suitability for the installation environment.

• Use grade information where structural performance matters.

• Choose lengths that reduce cutting waste against your cut list.

• Keep timber specification consistent across the full job.

 

Before you order

 

• Finalise your cut list by section and length.

• Calculate quantities, with allowance for offcuts and site adjustments.

• Confirm compatibility with fixings, connectors and adjoining materials.

• Check stock availability for all required lengths before checkout.

• Validate that all selected lines meet the job spec.

 

Explore our range of treated timber

Within our selection of treated timber, you can compare options across different lengths and section sizes to suit site requirements.

 

If you are using different types of timber, try to use the same level of treatment for the whole build. This will make ordering supplies easier and keeps the quality consistent across the site.

For wider requirements though, browse our collections of sawn timber and CLS studwork timber. For external ground and boundary work, you can also pair your timber order with fence posts and timber sleepers.
