Endura-Stone™ 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.
