Decking joists are the repeated structural assistance that are used to build a deck frame. Our decking joists are available both C16 and C24 strength grades. Kiln dried to reduce moisture content to allow the Tanalith E treatment to fully penetrate the product. The pressure treatment allows for protection against rots and insects. The decking joists are also regularised thus giving a smooth face on all 4 edges. This allows for the product to be widely used for a range of external joinery and decking applications, ranging from decking frame joists to outdoor furniture. The joists come in a variety of sizes and lengths to suit all needs.
