C16 timber is a strength-graded softwood widely used in structural construction across the UK. Builders typically use it for framing walls, flooring, roofing, and partitioning work. In modern construction, C16 timber provides a cost-effective option where high loads are not a major concern.
You can choose from a variety of sizes and profiles, including regularised, planed, and C16 CLS timber, which is common for internal studwork. Products are available either kiln-dried or pressure-treated depending on what you need. C16 timber remains popular for residential builds, garden structures, and temporary works where strength and durability must meet building regulations.

C16 timber is a grade of softwood defined by its strength and density. It’s commonly used in structural applications where moderate strength is sufficient, such as wall studs, floor joists, and roof timbers.
C24 timber is stronger, denser, and has fewer defects compared to C16 timber. Builders often choose C24 for higher load-bearing needs, exposed structures, or premium projects. C16 timber is more cost-effective and suitable for general construction where the highest strength rating is not necessary.
