A novel pillar is provided. The pillar having a longitudinal axis and first and second ends, an outer skin, an extruded support structure disposed within the outer skin, with the support structure including multiple cells arranged along the longitudinal axis for support of longitudinal loads, and a tension bar disposed at least partially within the extruded support structure. The outer skin and extruded support may include structural plastic, and the extruded support structure may be separately insertable into the outer skin. However, in an alternative embodiment the outer skin and extruded support structure are co-extruded as a single monolithic piece.
