System Design

Product details

STRONGDEK™ is a patented ultra-high performance structural composite decking system that offers unmatched strength and long-term durability in an aesthetically pleasing and easy-to-install package with virtually no maintenance required. Each board measures 5.5” wide x 0.94” thick, the same nominal dimensions as traditional 5/4 wood decking and most standard composite decking.

The STRONGDEK™ composite decking system is comprised of two main components:

Deck Plank

A pultruded fiber-reinforced polymer (FRP) thermoset composite structural member that offers the system’s strength and rigidity. Fastens to existing substrates using decking screws or similar fasteners.

Glass Fibers Encapsulated in UV Stable Resin:

  • Integrated Groove for Hidden Fasteners
  • Structural Strength & Performance

    Top Cap

    An extruded vinyl hybrid thermoplastic composite overlay that offers the system’s finished surface appearance, UV performance, and slip resistance. The cap can be removed and replaced without harming the structure or affecting its safety.

    Top Coat:

    • Aesthetics
    • Cool Touch
    • Slip Resistance

    Base:

    • Low Thermal Movement
    • Rigidity
    • Snap-On Hold Strength

    Each STRONGDEK™ board is lightweight (1.6 lbs/LF) yet outperforms 5/4 Southern Yellow Pine and high-end composite deck boards in nearly every performance category. This translates to a stronger overall deck surface capable of handling higher loads with standard 16” (or 24”+) joist spacing, even with boards installed on a diagonal.

    Color Options

    STRONGDEK™ composite decking system is available in these standard natural wood tones with realistic grain texture:

    Beachwood

    Slate

    Chestnut
