Some builds need more presence from the timber. More strength and more confidence in every fixing. That is where 4×2 timber steps in. This is the size builders reach for when the structure matters, not just the finish. When loads are higher, spans are wider, and the frame has to hold its line without compromise. From solid internal frameworks to outdoor structures that live through British weather, timber 4×2 is about doing the heavy lifting quietly and reliably. It is familiar on site, trusted in plans, and flexible enough to move from house builds to garden projects without changing the approach.
What is 4×2 C16 timber?
4×2 C16 timber is a structural softwood section strength graded for construction use across the UK. It is commonly supplied in finished sizes such as 4×2 CLS Timber timber or 4×2 Treated Timber, depending on planing and treatment.
The C16 grade confirms the timber meets recognised structural standards. It behaves predictably once fixed and stays stable through repeated use in framing. This is not timber chosen by guesswork. It is graded, tested, and supplied ready for real building conditions.
On site, 4×2 wood feels solid in hand. It cuts cleanly, takes fixings well, and stays true when used in long runs. Available in practical 4×2 timber lengths, it fits standard UK layouts without forcing awkward joins or waste. You will also see it referenced as timber 100x47mm or timber sometimes by the actual size 95x45mm, all working within the same 4×2 format builders already trust.
What is 4×2 timber used for?
Structural stud walls and load-bearing partitions
When walls need more substance, 4×2 C16 timber provides it. It is used for structural stud walls, main partitions, and areas where services, insulation and boards all need solid backing. This section helps walls stay straight and strong.
Floor joists and supporting frameworks
4×2 timber is commonly used for floor structures, secondary joists, and supporting frames where strength matters more than slim profiles.
Garden rooms, sheds and garages
For garden buildings that are used year-round, 4×2 timber forms the backbone. Roof supports, door openings and internal bracing all benefit from the extra depth. It keeps panels aligned and doors square, even after seasons of movement.
Deck framing and raised platforms
For decking bases, steps and raised seating areas, 4×2 timber is used where flex would become a problem. The section carries weight across longer runs and helps the deck feel firm underfoot, not springy or hollow.
Fencing, gates and privacy screens
Not just panels, but the parts that hold everything together.4×2 timber sections are often used for gate frames, heavy posts, slatted screens and privacy structures. They reduce sag, keep gates aligned and help fences stay upright through wind and weather.
Commercial interiors and fit-outs
In shops, studios and commercial spaces, 4×2 timber is used for framing walls, building service zones, creating display backings and forming concealed structural elements. It supports heavier finishes and repeated fixings without compromise.
