Millboard DuoSpan Joist 51 X 68 X 3600mm

DuoSpan® combines the strength of aluminium with the design flexibility of recycled plastic. This achieves a system that provides exceptional ease of installation, enormous strength and durability, and the scope to construct stunning decks and structures that would be impossible with conventional subframes.

DuoSpan® provides the perfect subframe for Millboard decking, as well as a universal support system for other outdoor flooring. Its ingenious design facilitates top-down fixing of decking boards and makes it an easy installation for all levels of competence.

DuoSpan® has been designed by industry professionals to comply with Eurocode 1: Actions on Structures (BS EN 1991-1-1), and is available in component form, or in five simple off-the-shelf kits, for ease of ordering.
