Abstract
A resin deck board has a top surface with a plurality of water drainage channels spaced from one another extending axially in the top surface of the board. The top surface of the board also includes a plurality of feed channels which are angled relative to and which intersect with the drainage channels. The drainage channels penetrate to a depth at least as great as that of the feed channels into the top surface of the board to promote water from the feed channels to drain in to the drainage channels which then carry the water off of the top surface of the deck.
