Flexible fence board material is provided which comprises a length of hollow plastic material having a pair of face surface portions separated by upper and lower edge wall portions, wherein thinned hinge regions are provided at each of four corners along respective intersections of the face surface portions and upper and lower edge wall portions to thereby permit the fence board to be collapsed to a substantially flattened configuration which permits rolling of the material. Expansion and contraction joints are provided to facilitate end-to-end connection of adjacent boards, and shape retaining sleeves are provided which maintain the hollow, rectangular configuration, especially in long fence sections. A related process of constructing a fence system is also disclosed.
