Architectural column materials
The choice of architectural column materials these days boils fown to wood, polyurethane and composite materials. The age and style of your home may require that you use wood to achieve an authentic look. Otherwise, wood is difficult to maintain, it can shrink or swell and can be easily damaged by the elements. Polyurethane is cheaper, but also softer and less durable. Composite materials (cellular PVC, reinforced polymer) are great for achieving a period look without using expensive and high-maintenance wood columns.
On occasion, you will also find fiberglass, aluminum and plaster columns. Stone columns are rare these days and their look can be reproduced using composite materials.
