Please note Columns that surround structural supports are typically split for reassembly so this chart allows for loss due to saw kerf. Columns that are split are no longer considered load-bearing. The inside diameter of decorative capitals is much smaller than the column shaft so the chart below will not work for decorative capital applications. To insure that the column ordered will surround the intended structural support, the column needs to be split by Royal Corinthian and the shape and size of the structural support needs to be indicated on the purchase order. Royal Corinthian will not accept any liability if columns are purchased not split and do not wrap the published structural support sizes. When a column is ordered full round (not split), it is implied that the column will not be used to surround a structural support. If the contractor intends to drop a full round (not split) column around the structural support, the shape and size of the structural support needs to noted on the purchase order at the time of order.

*Inside diameter relates to the shaft only and therefore columns with a Tuscan Capital. Decorative Capitals sit on top of the column rather than sliding over the shaft, thereby limiting the amount of area for additional support. Additional support is only required when a column is split and still needs to be supportive or load bearing. Split columns are not load bearing. Our columns are nominal

The two, nine foot columns, caps and bases were well-made with excellent detailing. It took approximately five weeks for the 370 lb. pallet to arrive at the door by semi-trailer. They’re heavy, but maneuvered and trimmed easily laid horizontally on a home-made door dolly. The website was clear, and easy to navigate for ordering. I recommend these columns.

Even better than I expected. Very solid, almost like stone. Looks perfect. Used them to replace wood columns that were deteriorating, they were almost an identical match. Can’t recommend highly enough.
