So many architects and builders select Turncraft Architectural Columns because they feature thoughtful product design, fine workmanship, superior assembly, precision turning and fluting, and artful finishing. Round columns may be ordered with true architectural entasis in sizes consistent with the classic proportions of the Greek Doric, Tuscan, Roman Doric, Ionic, and Corinthian Orders, or in custom shaft diameters up to 36" and lengths to 30'. They can be smooth surfaced or given dramatic deep fluting (with increased stave thickness) as desired. Greek Doric Columns feature classic edge-to- edge fluting. 

Square columns and pilasters may be ordered to match (available in tapered or non-tapered, and in various plan styles-see page 9). Non-tapered cylinders are available for use in casework, radius wall corners, and contemporary applications.

Pine

Redwood

Turncraft exterior columns and paint-grade interior columns are fashioned from select, kiln-dried Ponderosa Pine staves (or clear, vertical-grain, all-heart Redwood by custom order). Use of finger-jointed pieces conserves valuable wood resources, reduces potential for warpage and bow, and helps prevent checking or cracking of finished surfaces. (Solid-stave assembly available by custom order.)

Cherry

Mahogany

Stain-grade interior columns are fashioned primarily from solid-stave Red Oak, Poplar, Hard Maple, Pine, Cherry, Redwood, Mahogany, and Black Walnut lumber and feature matching wood Caps & Bases.

Walnut

Red Oak

Exterior and paint-grade interior columns feature polyurethane or fiberglass Caps & Bases (see charts) to provide crisp, true architectural detail and increased durability. (Special-order wood Caps & Bases are available.) Optional aluminum plinths provide an extra measure of protection.

Maple

The making of Turncraft columns is an exacting process. Finger-jointed or solid staves are milled to the required dimensions, aligned with tongue-n-groove joints, assembled using the strongest Type-1 waterproof glue, and metal- banded for curing. In the computer-controlled lathe, the assembled shaft is turned to the precise taper desired, complete with true architectural entasis. The top of each column is profiled according to the style specified, and the entire column is machine sanded to ensure a smooth finish.

Flutes are milled at precisely determined intervals and depths, always ending in full half-rounds top and bottom (except on Greek Doric). Each column, regardless of size, is visually inspected, any defects are corrected, and then it is finish sanded.

All paint-grade wood shafts, caps, and bases are fully immersed in Woodtreat^® MB preservative formulated to protect against mold, mildew, and staining, and decaying fungi; to control shrinking, swelling, end checking, splitting, grain raising, and warping; and for maximum compatibility with paint primers and topcoats.
