Decking Components & Materials
A decking subframe is the structure that sits beneath your deck, keeping it supported and providing the base that your decking boards are attached to.
The key to a long lasting deck is a well constructed subframe comprised of high quality materials, set correctly in an appropriate foundation.
Plas Pro is Millboard’s premium 100% recycled subframe material and can be used alone or as part of our new DuoSpan landscaping subframe system. This all-weather, durable and flexible material is a non-rotting alternative to timber and is perfectly suited to spaces exposed to damp, such as jetties, pools, roof terraces and boardwalks.
What is Plas-Pro?
Plas-Pro is made from 100% recycled plastic. By using selected graded materials and cleverly engineered processes, Plas-Pro provides key environmental benefits and the assurance of superior quality performance.

The ultimate support system for your frame. The DuoLift® joist pedestal system was designed to make installation significantly easier and to ensure successful outcomes. Providing substantial height flexibility within four stackable components, DuoLift® removes the common problem of having to order varying height pedestals for a single area. Height-adjustable from 15mm, DuoLift™ makes accurate height-setting easy, and is self-levelling from 35mm upwards.
With DuoLift®, you can quickly achieve a level support system that won’t rot, split or host algae. DuoLift®’s range of feet, pedestals, risers and cradles are even suitable for use in damp environments.
Providing an exceptional height range of 45mm, from 15-60mm, the DuoLift® Joist Cradle enables precision height adjustment with 5mm markings on the side and each quarter turn of the adjustment ring representing a 1mm rise or fall. The Joist Cradle allows the installer to adjust the height whilst the joist is in place, locking tabs provide a secure finish once correct height has been determined.
Product Code PMCP010
Adding 20mm to the height of the supports, the DuoLift® Self-levelling Joint provides easy and effective levelling of a subframe up to 5º, ready for decking installation. Suitable for standing directly onto a solid substrate, or for providing a joint for a higher support.
Product Code PMLP010
The Riser component of the DuoLift® system increases the height in increments of 45mm. It is capable of sitting directly onto a solid substrate under the Joist Cradle and Self-Levelling Joint or forming part of a higher stack with a foot beneath.
Product Code PMRP010
The DuoLift® Foot provides a very stable footing for more elevated subframes, raising the height by 45mm and spreading the load further across the substrate, due to the 220mm base supporting a maximum combined height of 350mm.
Product Code PMFP010
Agglomerated cork and recycled rubber pads offer a layer of protection between joist supports and membranes, as well as providing an acoustic benefit.
Product Code PMAP010
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.
Multiple bracket types for all types of joints, including Flexible Brackets for non-standard angles.
Screw-locating grooves and self-drilling screws ensure accurate alignment and a fast fix that’s right every time.
The combination of rigid DuoSpan® with flexible Plas-Pro enables the construction of stunning curved formations.
The DuoSpan® 99mm Joist provides an exceptional 1800mm span in residential applications, reducing posts or joist supports required.
Galvanic corrosion between different metals is minimised with our cathodic barrier fixings.
Decking and cladding can be easily and securely screwed directly into the DuoSpan® subframe at almost any angle using Durafix 45mm screws.
A bold showstopper and demonstrates both elegance and decadence in equal measure.
