Square Recessed Panel Columns
Royal Corinthian manufactures square non-tapered recessed panel columns from 4 composite materials: RoyalCast™ Composite Fiberglass, RoyalStone™ Synthetic Stone, RoyaLite™ FRP Lightweight Fiberglass, and RoyalWrap™ PVC. We only offer composite materials because we want these columns to last for generations. We also offer RoyalCrete™ GFRC columns for those wanting a cast stone product with a segmented look. If you know which material is most suitable for your project, you can find the available sizes, various dimensions, and other specs in the charts below. If you desire to learn more about our materials, please call us for a quick run through or check out the comparison chart on our column page. For sizes and specifications for our recessed panel PVC column wraps, please visit our non-tapered PVC column wraps section.

*Load bearing capacities and average wall thicknesses apply only to RoyalCast and RoyalStone. Wall thickness at panel will be significantly less than at the top and bottom of the column and is not considered in the average thickness. RoyaLite FRP column covers have a average wall thickness of 3/16” and only bear minimal weight when factory assembled. 14″ and 16” Columns have an astragal and capital support ring that is part of the shaft while the other sizes are available with an optional loose astragal. The astragal is 8” and the support ring is 4-7/16” from the top on the 14” column. The astragal is 9″ and the support ring is 5-1/8″ from the top on the 16” column. Astragal and/or support ring can be removed if desired. Specs for GFRC columns are available upon request.

8” | 5-3/8” | 5” | 3-1/2” |
10” | 7-3/8” | 7” | 4-7/8” |
