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 pressure-treated timber, measuring 6000mm in length with a 75mm x 100mm (4" x 3") section.

Broad profile provides a stable fixing surface for structural applications in general construction, floor joists, and heavy-duty framing support. This product is kiln-dried prior to treatment to ensure dimensional stability and consistent preservative penetration, providing reliable performance in external environments.


Features & Benefits

  • Pressure treatment: Helps extend service life in outdoor or damp conditions.
  • Square-cut edges: Consistent profile for tight fixing and alignment.
  • Natural timber appearance: Suitable for both construction and landscaping contexts.
  • Workable softwood: Easy to cut, drill, and fix using standard tools.
  • Engineered construction: Features finger-joints with high-strength glue lines that are stronger than the timber itself.
  • Defect-free finish: Engineered process removes knots and natural defects for consistent quality.
  • Enhanced strength: Up to 60% stronger than solid timber alternatives.
  • Kiln-dried and treated: Dried for stability and pressure-treated with Tanalith E for enhanced durability.
  • Length 6000mm: Reduces the number of joints in extended runs.
  • Section 75mm x 100mm (4" x 3"): Heavy-duty profile provides a stable structural base for versatile use.


Applications

  • Structural framing support: Provides a high-strength base for floor joists, roof joists, and primary load-bearing frameworks.
  • Heavy-duty construction: Suitable for large-scale external builds, decking sub-frames, and outdoor structures.
  • Construction detailing: Robust enough for heavy-duty stud work and primary structural support in outbuildings.


Installation Guidance

  • Set out timbers evenly: Ensures consistent load distribution and prevents material warping.
  • Use galvanised or stainless fixings: Protects against corrosion and prolongs service life outdoors.
  • Maintain ventilation gaps: Supports insulation performance and prevents trapped moisture behind structural cladding.
  • End-grain protection: Seal all cut ends and notches with a suitable end-grain preservative product to maintain treatment integrity.


Compliance & Performance

  • Preservative treatment: Pressure treated with Tanalith E for durability and resistance to fungal decay and insect attack.
  • Service conditions: Intended for use above ground, where timber may be subject to occasional moisture but not constant wetting or ground contact.
  • 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: 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.
  • Important note: Colour and finish may vary from green to brown depending on the treatment process; this product is C24 graded and suitable for structural applications.
