System Design

Lightweight & Resilient

A STRONGDEK™ board is made up of two components: a pultruded FRP plank and a snap-on hybrid composite top cap. The plank offers the board’s structural strength, rigidity, and integrated hidden fastener grooves. The top cap offers aesthetic beauty, a non-slip surface, UV resistance, and an overall finished look for the system.

How it Works

STRONGDEK™ can be installed on top of any existing substrate suitable for a deck. Components can be cut using traditional carpenter’s tools fitted with a non-toothed diamond or carbide grit blade.
