Composite Joist/Battens Features and Benefits Create a durable, weatherproof, and low-maintenance foundation for your composite decking by using our low-profile composite joist for your decking frame. Our composite battens are everything you need to make your project a success. Our composite joist is engineered to resist rotting, warping, splintering, and splitting, ensuring long-lasting support without the need for treatment or frequent replacement like traditional timber joists. Designed for versatility, it can be installed either side up and is ideal for solid, weight-bearing bases such as concrete. To attach your decking boards securely to our composite battens, use our range of decking clips, which perfectly complement the composite joist system. Additionally, the composite joist serves as an excellent frame for composite cladding. Simply attach it to the wall or structure, and install the cladding directly over it for a sleek, secure finish.
