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.

Product Overview
Sawn Treated Timber with a 47mm thickness and 100mm width, provided here in a 3m length. This structural softwood is strength-graded to C16/C24 standards, ensuring reliable performance for essential carcassing tasks in floors, roofs, and wall framing. Each piece is kiln-dried to improve dimensional stability and pressure-treated with Tanalith 'E' to provide robust resistance against fungal decay and insect attack, making it suitable for long-term use in internal or protected external environments.
The timber is regularised to ensure consistent sizing for accurate framing, while the sawn face texture provides a reliable grip for adhesives, membranes, and various surface coatings. Featuring eased edges, the timber is easier to handle on-site with a reduced risk of splintering. This 3m length is specifically suited for medium-span joists, structural trimmers, and build areas requiring a 47mm x 100mm size.
Features & Benefits
- Strength grading (C16/C24): C16 for standard domestic builds; C24 for higher loads and reduced deflection.
- Factory applied preservative treatment: Protects timber in typical above-ground conditions when installed properly.
- Kiln-dried & regularised: Helps control shrinkage and ensures even sizing for accurate work.
- Eased edges: Safer handling and a cleaner finish with reduced splinter risk.
- Sawn face texture: Provides a stable key for membranes, adhesives, and coatings.
- Easy to work: Accepts nails, screws, bolts, and hangers.
- Length - 3m: Suited to common bay sizes and moderate spans.
- 100mm width: Dependable bearing for floor joists and stud walls.
- Section size - 47mm x 100mm (4" x 2"): Widely specified in structural carcassing.
Applications
- Floor joists and trimmers: Provides structural spans for supporting floor loads.
- Stud walls and plates: Creates a reliable timber framework for internal partitions and walls.
- Roof members: Serves as rafters and ceiling joists for standard pitched roof configurations.
- Structural Joinery: Used for general framing where a load-bearing requirement exists.
Installation Guidance
- Structural Spacing: Ensure all timber members are installed according to the specific load requirements of the project.
- Stud Wall Alignment: For detailed layout instructions and centre-to-centre measurements, refer to our guide on how to build a stud wall.
- Fixing Selection: Use high-quality wood screws or galvanised nails of sufficient length to ensure a secure mechanical bond between timber members.
- End Grain Treatment: Apply a brush-on preservative to any cut ends or notches to maintain the integrity of the chemical treatment.
- Level and Plumb: Utilise a spirit level or laser level to ensure all vertical studs and horizontal plates are perfectly aligned before final fixing.
Compliance & Performance
- Strength grading: C16/C24 to BS EN 14081 / EN 338.
- Preservative treatment (Tanalith ‘E’): Pressure treatment provides resistance against fungal decay and insect attack.
- Dimensional tolerance: Finished sizes typically arrive slightly under nominal, often around 2mm less in thickness and 5mm less in width.
- 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.
