An assembly comprises a supporting substructure and at least one longitudinally extending board member supported on the substructure. An edge member is mounted proximate an end portion of the board member and has a lower portion configured for attachment to the substructure, and an upstanding wall portion extending from the lower portion. The upper wall portion defines an open channel and provides an opening into the open channel. The edge member is attached to the substructure and the end portion of the board member is received through the opening of the edge member into the open channel. The channel can accommodate longitudinal expansion and contraction of the board member. The board member may be made of a natural fiber thermoplastic material. The assembly may be configured as a deck assembly.
