Abstract
A deck plank comprising a substantially flat top surface made preferably from a wood replacement material having a first edge and a second edge, and may also have a tongue attached to the first edge and a groove attached to the second edge, the tongue and the groove each extending in a plane below the top surface downward from the top, the tongue being adapted to fit with a groove of an adjacent plank. The tongue and the groove are shaped so that a space is maintained between a portion of the tongue and a portion of the groove of the adjacent plank when the tongue is placed adjacent to the groove of the adjacent plank. A number of the deck planks can be used to make a deck.
