As with all our fiberglass polymer columns, these are structural if used whole or used as a square column wrap around an existing structural member. The 12″ square column are manufactured smooth without the astragal (neck ring). The astragal is optional and is normally added with the Tuscan capital.
We manufacture square columns as one piece from fiberglass reinforced polymer (FRP). Infused with marble dust, FRP columns have a stone-like feel. The square column design has a somewhat more modern look than their round counterparts. These columns are load bearing, but also can be used as a decorative wrap as needed. And yet they feel and sound solid because of the hard dense nature of the column material.
Weatherproof, insect-proof, rot-proof, virtually maintenance free, pound for pound stronger than concrete, steel, or aluminum. This is the premier option for columns. Works great with either wood or synthetic balustrades. Interior or exterior use. Use acrylic-latex primer and paint for best results. Whole columns are load bearing. See capacity chart below.
Split/reassembled a square column wrap is NOT load bearing. The idea of a split column is that it can be used around a supporting post, or as a pilaster against a wall. Optional Reassembly Kit available for those ordering split columns to be reassembled around an existing member. Includes necessary ties, spacers, and filler. Two kits are required or columns 14′ high and taller. No warranty provided on split columns.
Square columns are available custom fluted. We will flute columns for your specific overall opening height. Just drop us a note on how tall the finished column will be, and we’ll make the flutes to start at the appropriate height on the column shaft. (Click here for a further discussion on fluted columns)
Column Capitals and Bases:
12″ square Tuscan column caps and bases are made of polyurethane, which is a high density foam like our synthetic balustrades.
Attic bases are made of Fiberglass Polymer, the same material as the square column shaft.
Craftsman caps and bases are made of cellular PVC.
All caps and bases fit around the shaft and DO NOT affect the overall height of the square column.
Ornamental capitals (Ionic, Corinthian, etc.) are available for square columns. Call or email for pricing and information.
Every Column Shaft includes a Column Installation Kit. The Install Kit contains hardware to install round and square FRP columns in just about any application. Brackets are bolted to the column, then Tapcon screws attach the top brackets to the ceiling/soffit. Kit includes full instructions on installing FRP columns.
Craftsman Pedestals available for these square columns. Call or email for more information.
