Installers should make sure that any timber for structural applications is appropriately graded - i.e. C16 or C24. Sawn timber does not have a smooth finish suitable for decoration, and so if the wood is to be exposed we would recommend a planed all round timber. Where there are technical and structural elements to an installation, we always recommend that you consult a professional who can advise on the specific requirements for your property.

Product Overview
Sawn Treated Timber C24 featuring a 47mm x 100mm profile and a 4.2m length. This high-grade structural wood is pressure-treated to resist rot and fungal decay, providing robust load-bearing performance for demanding building environments.
Great for garden framing, custom sheds, or matching specific room dimensions to avoid excessive off-cuts.
Applications
- Internal stud walls: Forms the vertical framework for non-load-bearing and load-bearing partitions.
- Floor joists: Provides structural support for localised flooring spans and reinforcements.
- Roof construction: Suitable for rafters, structural bracing, and ceiling joist assemblies.
- Noggins and blocking: Ideal for horizontal bracing between vertical studs over short distances.
Compliance & Performance
- Finished sizing: Precisely finished to a 45mm x 95mm profile, ensuring consistent dimensions across the entire length for accurate framing and structural alignment.
- Natural variation: Colour and surface appearance vary naturally and by treatment batch.
- Moisture disclaimer: Treated Timber is often stored outside and if it has recently been raining then the timber may arrive wet; this does not affect the integrity of the timber.

How delivery works
We work with a nationwide network of trusted suppliers. Items in your basket may be supplied by different suppliers and delivered separately. Where this applies, you will see delivery charges shown at checkout for each part of your order. We always aim to group products from the same supplier to keep delivery costs as low as possible.
Delivery areas
Delivery charges apply to mainland UK, excluding: AB, CA, CF, DD, DG, EH, EX, FK, KA, KW, KY, IV, LA, LD, LL, ML, NP, PA, PH, PL, SA, SY, TR, TQ and TD.
If your address is in one of these areas, we will contact you before processing your order to confirm any additional costs. We do not currently offer delivery outside the UK mainland.
What to expect on delivery day
- Deliveries are typically kerbside.
- Please ensure someone is on-site to accept delivery. For heavier items, help with offloading may be required.
- Many building materials arrive on large vehicles. If access is restricted, a specialist vehicle such as a HIAB may be required and could incur an additional charge.
Why delivery can cost more than typical parcel delivery
Building materials often travel on larger vehicles and usually carry fewer drops per run than parcel networks. That is why delivery charges can be higher than standard e-commerce shipping.
Returns
Returns depend on what you have bought and whether there is anything wrong with it. For full details on eligibility, timeframes, and exclusions, please see our full policy.
