Designed to do more. Engineered to last.

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.

Installing on solid surfaces

When installing on solid/stable surfaces, such as a paved patio or roof terrace, DuoLift provides a perfect support system for the framework.
