Product Overview

Sawn Treated Timber C24 featuring a 47mm x 100mm profile and a 2.4m length. This high-grade structural wood is pressure-treated to resist rot and fungal decay, providing robust load-bearing performance for demanding building environments.

Perfect for vertical wall studs because it matches standard UK plasterboard heights of 2400mm, meaning zero vertical wastage and easy indoor maneuverability.


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.

Questions and Answers

Can treated 4x2 timber be used outside?

Yes, treated 4x2 timber can be used outside above ground. If you cut the timber, you must apply an end-grain preservative to the cut end, or the protection will be compromised and the wood will rot from the inside out.

answer supplied by James Herbert on 26 February 2026

What length 4x2 do I need for a stud wall?

You should choose a length that allows for a single, continuous piece from the floor to the ceiling to ensure structural integrity. Always buy timber slightly longer than your floor to ceiling measurement to allow for precise trimming to fit.

answer supplied by James Herbert on 26 March 2026

How do I ensure I am ordering C24? I dont want C16 grade.

The best way to do this, would be to add a note in the "Note for Delivery Driver" section of the order stating that C24 is required. Our team will pick this up and make sure that the order is allocated accordingly.
