half column shaft

A half column shaft is the decorative polyurethane element that forms the main vertical section of a wall-mounted half column, running between the capital and the base. It forms the visible surface of the column and can be produced with a plain or fluted (channelled) surface. Because it is made of polyurethane, it is lightweight and easy to install; it resists moisture and impact and does not crack or swell. As the surface is paintable, it can be matched to marble or stone looks. It is fixed to the wall and the other parts with adhesive and screws; when needed, its height can be cut to fit. Polure produces shaft elements to match the capital and base dimensions, so the parts join together neatly. The half column shaft is the main vertical component of a half column composition, defining the height between the capital and base and setting the overall form of the column.
