Marineplank is an excellent choice for both commercial and residential applications, and really shines when used in spaces that receive high traffic or are exposed to harsh weather conditions. It has been used by some of Australia’s leading architects and builders for projects such as the Perth Stadium, Marina boardwalks and high-end residential projects.

Marineplank can be installed on timber or steel joists and is designed for bearers and joists that are compliant with the AS1720 and the National Construction Code. Spacers should be used to maintain a consistent gap between the decking boards and adjacent walls. Each board is fixed to each joist with two screws per board per joist, and four screws should be used where boards are butt joined.
