DuoSpan and DuoLift - landscaping subframe systems


How do DuoSpan and Duolift work?

DuoSpan is a unique landscape construction frame that combines the strength of aluminium with the design flexibility of recycled plastic. This combination enables distinctive design opportunities for decking and outdoor structures that would be impossible with conventional subframes.

DuoSpan provides the perfect subframe for Millboard decking and is also a universal support system for other types of outdoor flooring, cladding and more ambitious outdoor constructions.

The system is precision engineered for durability, design versatility and for exceptional ease of installation – in fact, the system’s ingenious design makes it near-impossible to get assembly wrong. DuoSpan enables landscape builders to easily incorporate curves, steps, seating, pergolas, planters and much more into their outdoor designs.

DuoSpan is designed to work harmoniously with Millboard’s new subframe support system, DuoLift.

DuoLift provides firm, structural stability and offers accurate height adjustment. This user-friendly support system makes installation significantly easier and ensures a successful outcome, every time. With its combination of stackable components, not only does the system remove the need to have multiple height pedestals over a single area, but it also allows painless adjustment from 15mm to 60mm within the cradle, and an impressive total elevation capability of 600mm with the maximum combination of locking components.
The Millboard Design Hub can be found at 63 Goswell Rd, London EC1V 7EN. For more information about DuoSpan or DuoLift ahead of Clerkenwell Design Week, please visit
