PermaCastHB&G PermaCast Columns are great for many applications. They can be used as front porch support columns or decorative columns, and are available in both round columns and square columns. Round columns can be fluted or plain, with or without the classic tapering of the upper two-thirds of the column. Square columns are available in a variety of styles, including plain, fluted, applied or recessed panel, and craftsman. PermaCast capitals and bases are made from durable, low-maintenance materials, and, like the columns, maintain architectural authenticity and historical accuracy.
