The columns that are manufactured for home and commercial construction today are based on designs, size ratios and features that were first developed by the architects of ancient Greece and Rome.

The three basic orders of Grecian architecture are the Doric, Ionic and Corinthian. The Romans adopted the Greek design concepts and added at least two of their own, later defined as Tuscan and Composite. The Tuscan order was a Roman variation on the simple Doric Grecian order and characterized by their round, non-tapered columns of the Tuscan order.

The Tuscan round non-tapered columns favored by the Roman industrial architects were stockier in dimension than their Doric counterparts, which were designed to be about four times as high as they were wide. Round non-tapered columns provide a look of solidity that more slender, fluted columns do not. There is a high-end quality to the permanence implied by simple columns.

The round non-tapered columns available today are available in a variety of heights and diameters. They incorporate the simple, yet elegant Tuscan bases and capitals, round disks that fold into the flat square blocks mounted at either end of the column. Available in three quarter, half and one quarter dimensions, contemporary round non-tapered quarter columns can fill an inside corner, wrap around an outside corner or wrap around an existing support.
