Whether you’re building extensions, roofing, or general framework, our C16 carcassing timber gives you the strength and reliability you need at some of the best prices in the North West.

We’ve been supplying builders, joiners, and DIYers across the North West for over 100 years, and because of our experience in the industry, we know that quality materials make all the difference. That’s why every piece of our C16 timber is carefully graded, kiln-dried, and machined for a precise, consistent finish.

What Is C16 Timber?

C16 timber is one of the UK’s most popular and versatile construction materials. The “C” in the name stands for Coniferous softwood, and “16” refers to its strength grade. This makes it ideal for most structural and load-bearing applications such as joists, rafters, wall studs, and flooring.

Every length of C16 carcassing timber is graded on its strength and durability, ensuring it performs under pressure. For projects requiring even higher strength, we also stock C24 carcassing for longer spans or heavier structural work.

Why You Should Choose Our C16 Timber

Like all our timbers, we take pride in supplying FSC-certified C16 timber that’s responsibly sourced and perfectly prepared for construction. Each piece is kiln-dried to reduce moisture content and improve stability. Why is this important? By kiln-drying the wood it helps to prevent warping, twisting, or shrinkage once you install it.

Our C16 carcassing timber features eased edges for easier handling and installation, and can be ordered in different lengths to suit your project. We also stock treated carcassing timber for outdoor or damp environments where additional protection is needed.

C16 Carcassing Timber FAQs

Where and what would you use C16 timber for?
Most of our customers use C16 timber for typical structural applications like joists, rafters, stud walls, and general framework. It’s strong, reliable, and perfect for both domestic and commercial building projects.

Is C16 timber suitable for outdoor use?
Standard C16 timber is best used indoors or in covered areas. For outdoor or exposed applications, we recommend our treated carcassing timber which is protected against rot, moisture, and pests.

What’s the difference between C16 and C24 timber?
Both are structural timbers, but C24 timber has a higher strength rating and can handle greater loads or longer spans. You can find it here: C24 Timber.

How Long Does C16 Carcassing Timber Last?

C16 carcassing timber can last for several decades when correctly treated, installed, and maintained. In most construction settings, it will perform reliably for 40–60 years, and often longer if kept dry and well ventilated. Pressure treatment protects the timber from rot and insect attack, while regular care helps preserve its strength and stability, ensuring it remains durable throughout the lifespan of a building or outdoor project.

Yes. All our C16 timber is FSC-certified and sourced from responsibly managed forests to meet UK sustainability standards.
