A classic column is a column designed in one of the five classical orders (Tuscan, Doric, Ionic, Corinthian, Composite), with the proportions and the details of the classical canon. The classic column is a timeless design element, used in formal traditional interiors and grand architectural compositions.
A PU classic column is a factory-made column, designed to replicate the proportions and the details of a classical column. The column has a fluted or smooth shaft, a capital in one of the five classical orders, and a matching base. The proportions follow the classical canon.
The most common classic column application is a grand entryway. A pair of substantial columns, 250 to 400 millimeters in diameter, 2.7 to 3.6 meters tall, with Corinthian or Composite capitals and Attic bases. The columns frame the entry and set the tone for the entire interior.
A second common application is a formal living room with a colonnade. A series of columns along one wall, creating a colonnade that defines the room. The columns are typically 200 to 300 millimeters in diameter, 2.4 to 3.0 meters tall, with developed capitals and bases.
A third common application is a hotel lobby or a grand commercial space. A series of columns defining the space, with developed capitals and bases. The columns add a classical element to the commercial space.
For sourcing, PU classic columns are a stock product at most factories that produce classical columns. The factory offers a range of standard classic column designs (Tuscan, Doric, Ionic, Corinthian, Composite) in a range of standard sizes. Custom designs are available on longer lead times.
A practical install note: a PU classic column is installed the same way as any other column — assembled on site, stood in place, secured at the top and bottom, and finished. The column is typically painted in the room's trim color, with the details of the capital and base brought out by the painter's topcoat.
A practical note on the proportions. A classic column should follow the classical proportions, with the diameter-to-height ratio matched to the order (Doric is the stoutest, Ionic is more slender, Corinthian is the most slender). The column's proportions should be checked against the classical canon before the order is placed.

Frequently Asked Questions
Q: What are PU columns?
A: PU columns are polyurethane molded columns — typically Tuscan, Doric, Ionic, or Corinthian — that replicate carved stone or wood at a fraction of the weight. They ship in two or three halves for assembly around an internal structural post or as a hollow decorative shell.
Q: Are PU columns load-bearing?
A: Standard decorative PU columns are not structural on their own. They are designed as a 2- or 3-piece shell that wraps an internal load-bearing post (steel, wood, or reinforced concrete). For structural applications, specify "structural PU columns" with an internal steel core — these are engineered and tested to published load ratings.
Q: How tall should decorative columns be?
A: For a standard 8 ft (2.4 m) ceiling, use a 96-inch (2.4 m) column shaft plus capital and base, totaling about 100–104 inches overall. For 10 ft (3 m) ceilings, use a 120-inch shaft. Custom heights are available up to 20 ft (6 m) for atrium and lobby installations.
Q: How do you install Classic columns?
A: Mount the base plate to the floor with anchor bolts. If structural, set a steel post first; if decorative, mount an internal PVC pipe for rigidity. Assemble the two or three PU column halves around the post, glue the seams with PU adhesive, and clamp for 30 minutes. Mount the capital and base with construction adhesive. Fill and sand the vertical seam, then paint.
