Composites

Composite decking combines material formulation, surface finish, and board profile. Check the exact product line and profile before comparing dimensions or accessories.

Before choosing your setup

  • Compare actual board dimensions and lengths for the exact product line.
  • Check square-edge and grooved profiles against the manufacturer’s approved fastening options.
  • Compare material samples, care instructions, and the finished deck requirements before selecting a color or finish.
