VersiFrame® Decking | Outdoor Floor Decking Solutions

What is VersiFrame®

VersiFrame® is an aluminium joist system developed to be used in conjunction with VersiJack® pedestals to construct a more stable and versatile substructure for indoor and outdoor floor decking. It improves heat and sound insulation, facilitates rapid surface drainage and creates an easily accessible chamber to conceal mechanical and electrical services.

VersiFrame® is connected to VersiJack® pedestals using an adaptor and once locked in place, the substructure prevents pedestals from unintended movement during installation, maintenance and everyday traffic atop the raised deck.

VersiFrame® is designed for seamless compatibility with most conventional fixings and deck board profiles available in the market.
