Abstract: A decking system comprises a ledger board for mounting on an upright supporting surface, a beam, a plurality of joists for spanning between the ledger board and the beam, and a plurality of deck boards for spanning across the joists in which all of the components can be mounted to one another by interlocking engagement of various connectors so that no additional fasteners are required for assembly. The components are formed of extruded and molded materials which do not require any maintenance. A railing system and a stair system are also provided which similarly connect by interlocking engagement of the components.

Abstract: A plurality of intermediate deck boards span across joists in a decking system in which each deck board includes a lower frame portion extruded of a first material and an insert body inserted into the top side of the lower frame portion which is formed of a second material. Additional extruded members are used as starting and ending rows of the deck boards and as finishing boards across the ends of the intermediate deck boards, in which each of the deck boards defines a respective portion of an upper deck surface of the assembled deck structure. The perimeter extruded members include mounting channels for mounting a railing structure thereon.
