Buy Treated Carcassing Timber

Our carcassing timber is a durable, cost-effective choice for both internal and external construction projects. Made from treated timber and graded to C24, it's ideal for load-bearing applications such as floor joists, roof joists, and timber framing. If you're working on something more demanding, this higher grade of carcass timber offers the strength and reliability needed to get the job done right.

Manufactured using a pressure treatment and careful drying process, our carcassing timber is resistant to moisture and performs exceptionally well in structural roles. This makes it not only ideal for interiors but also a solid choice for outdoor projects, including fencing, decking, and pergolas, where long-lasting support is essential.

All of our timber carcassing is clearly marked by grade, but if you're not sure which type is best for your project, our knowledgeable team is always happy to guide you. Whether you're a trade professional or a DIYer, we're here to help.
