Millboard® Subframe & Accessories

Although out of sight, what goes on beneath your deck is as important as its surface. Our Plas-Pro subframe system, made from solid, 100% recycled plastic, needs no maintenance and won’t suffer from insect attack or damp – you can even use it to support a deck over a pond! Along with a range of joist supports and self-levelling pedestals for easy installation, it is designed to last as long as the Millboard decking it supports.
