Tanalised Decking Joists – Strong, Treated Timber for a Long-Lasting Deck Frame A solid deck starts with a strong framework. Our Tanalised Decking Joists provide the ideal foundation for any decking project, offering strength, durability, and long-term protection against the elements. Manufactured from quality softwood and pressure treated for outdoor use, these joists are built to perform season after season. Each joist is tanalised – pressure treated with preservatives – to guard against rot, fungal decay, and insect attack. This treatment penetrates deep into the timber fibres, making the joist suitable for ground contact or use in damp environments where untreated timber would quickly deteriorate. Reliable Support for All Decking Projects Whether you’re building a raised deck, ground-level platform, or a multi-level structure, a Tanalised Decking Joist gives you the confidence to build safely and securely. With proper spacing and support, these joists provide a stable base capable of handling foot traffic, furniture, and seasonal wear without warping or sagging. Available in various lengths and dimensions, they’re suitable for residential and commercial builds. Easy to Cut, Fix and Fit Our decking joists are easy to work with using standard tools. They’re perfect for professionals and capable DIYers alike, and they’re easy to cut to size, drill, and fix into place. The straight, planed finish creates simple alignment and consistent spacing beneath your decking boards. Sustainable and Responsible All of our timber is sourced from responsibly managed forests.
