Resin-7 - Resin-7 Construction boards are single pressed meaning that each board is identical to its brother on the shelf. Made from 7-Plys of Canadian Hardrock Maple, the Resin-7 construction uses a gnarly epoxy that allows for more strength with less glue. All this means that Resin-7 decks are considerably lighter, stiffer and longer lasting than traditional 7 ply construction.
