ROUND TAPERED ENDURA-STONE™ COLUMNS

The Endura-Series™ Round Tapered Column is the column of choice among builders and home owners alike. This versatile column combines elegance and boldness to truly define exterior spaces. This Column also features a durable Endura-Stone™ construction that stands up to weathering and insects.

This simply styled column features just the right amount of detail for a crisp and architecturally rich appearance. We offer the Endura-Series™ Round Tapered Column in classical proportions for those in search of a historically accurate product. This column is inspired by the Doric and Tuscan columns of ancient Greek and Roman architecture. Like its ancient predecessors, it features a entasis (a slight bulge at the center of the column shaft), and a gracefully tapered form. Ancient architects believed that these elements combined to produce the most aesthetically effective and visually pleasing column. Today, their principles live on in the Endura-Series™ Round Tapered Column.

Endura-Series™ Round Tapered Columns are offered with both fluted and non-fluted shafts. For projects that require unique proportions, we also offer the round tapered column with custom width and height measurements, made exactly to your specifications for an ideal fit and appearance.

Note:

The content of this column specifications data is in accordance with the provider of these products: Pacific Columns, Inc. We only perform the hand painted finish and resale them. For more information or any technical question, please feel free to contact them directly at: 1-800-294-1098.

Round Tapered Column Shafts

Tuscan Columns are available in fluted or unfluted versions. They may be ordered in Vignola’s architectural proportions or in custom combinations of column lengths and widths as well as in non-tapered cylinders. Square architectural columns and pilasters to match detail of round tapered columns are available.

Column Plan Types

Endura-Stone Columns are as unique as the different types of installations that are available. We offer our Endura-Stone™ Columns in a wide variety of “Plan Types”. These “Plan Types” are the style and type of shaft, capital, and base you will receive. If you are using them as half columns against a wall, you would want to select a “D” plan type for round or “F” plan type for square. This would give you a column that could be installed against a wall. These are the most common plan types, however, we can do custom plan types if your project requires it.

Column Splitting

Using a precision splitting template machine, columns can be divided in halves to be used as pilasters or to be reassembled around existing structural members. Columns designed for reassembly come with realignment splines and installation instructions.

Calculated Safe-Load Capacities

The sample columns tested supported loads at least four times the calculated value above prior to failure. The load was applied concentrically through the axis of the column. Loads shown are valid only if there is uniform contact between the full area of column ends and the cap & base units. Loads are provided for your convenience only and are not exact values. Consult a structural engineer for the most accurate load estimates.

*Concentric Load: A load which passes through the centroid of the cross section of a structural member and acts normal to the cross section.
**Eccentric Load: A load imposed on a structural member at some point other than the centroid of the section.
