6x2 Treated Timber 3600mm
6×2 treated timber is chosen when the structure matters more than decoration. When you need strength you can trust and timber that behaves the way it should once it is fixed in place.
This size is a familiar choice for builders, landscapers and homeowners working on real projects. Garden frames. Deck substructures. Outdoor seating areas. Raised beds. Chill zones that stay solid season after season. It is timber for people who want to build once and not come back to fix it later.
What is 150×47 treated timber?
150×47 treated timber is pressure treated structural softwood, commonly known on-site as 6×2. You may also hear it called by its actual size – 145×45 treated timber. Different names. Same practical section. UK sizing standards and planned dimensions explain the numbers, but in real builds, this timber is treated, graded and used as one consistent size.
This is 6×2 treated C24 timber, designed for strength, stability and resistance to moisture. The pressure treatment protects the wood against rot and decay, making it suitable for outdoor use and damp conditions. The C24 grade gives confidence when the timber is carrying a load, spanning longer distances or forming the backbone of a structure.
Some builders still refer to it as 6×2 green timber, but once installed, it is chosen for reliability, not colour. It is kiln-dried, treated and ready for site use, with predictable performance once fixed.
If you want timber that stays straight, holds fixings well and copes with British weather, this is the section that keeps coming back on quotes and material lists.
What is carcassing timber 6×2 used for?
Carcassing timber 6×2 is used wherever strength and structure come first.
- Decking subframes and garden platforms
- Pergolas, outdoor seating frames and chill areas
- Raised flower beds and garden structures
- Roof structures, joists and framing
- Stud walls and load bearing carcassing
In gardens, this size is especially popular. It gives enough depth to stay rigid, even when supporting planters, benches or covered areas. Less bounce. Fewer joins. Cleaner lines. For outdoor projects that are used every day, this timber makes the difference between something that feels temporary and something that feels built.
Benefits of 6×2 treated C24 timber
6×2 treated C24 timber is made for structural work where the timber needs to do its job without surprises. The C24 grade gives higher strength and better span performance compared to lower grades. It is chosen when the frame needs to stay solid, not flex or sag over time. Pressure treatment protects the timber from moisture, rot and decay. That makes it suitable for outdoor builds, garden structures and damp conditions commonly found on UK sites.
