You’ve never seen decking quite like this.

Symmetry Decking in Action

Symmetry Decking offers the most natural look, feel, and colour palette available today in luxury composite decking, all balanced with time-tested durability and performance.

The low-gloss formulation and unique micro-texturing process create a beautiful matte finish. Multi-tonal streaking echoes elegant hardwoods. And the colours? Inspired by natural elements and pigments, the palette is subdued yet striking.

Equally impressive is the uncompromising performance and easy maintenance. Our four-sided PermaTech cap layer resists fading and staining, while the durable composite core means no splintering, cracking, insect infestation, or decay.

  • Beautiful, realistic wood looks

    Exotic wood tones and grains emulate hardwoods.

  • FAQs
    ​Why don’t I see a repeating pattern on Symmetry boards like I do with some other decking?

    Symmetry Decking is manufactured to have more random, natural graining than you’ll find with other deck boards. There are no visible repeats or easy-to-discern patterns.

    ​How do I clean Symmetry Decking?

    For general cleaning, use soap and water or mild household cleaners.

    How much ventilation is required under a deck?

    It is very important that there be adequate and unobstructed air flow under the deck to prevent excessive water absorption. Improve drainage or grade flat areas where standing water may gather. For decks with limited ventilation, six inches of clear ventilation is required.

    What if my decking gets scratched?

    In the same way that wood decking materials can get marred or gouged, the surface of composite decking can also be scratched. Horizon Decking is the Fiberon products most resistant to scratches. If scratches do occur, we recommend allowing normal wear marks to disappear gradually.
