Classic Aluminum Columns
Columns, Inc. began in 1963 with only an idea... to create a product that would revolutionize the column industry. A column that would not decay, check, split or be destroyed by insects. A column that would be less expensive to purchase, less expensive to maintain, beautiful to the eye and stronger than existing columns. Installation should be simple.

Classic Aluminum Columns answer every requirement. Laboratory tested and architecturally specified for today's maintenance free construction... we present Classic Columns, by Columns, Inc.

Structural Integrity, Lifetime Durability
Easy to Assemble: Classic Columns are straight, made in sections, each stave or section having a small and a large curved hook, which interlocks permanently to the adjoining section. Flange-type caps and bases slip over the columns to complete the unit.

Load Bearing Structural Members: Classic Columns are self supporting . . . designed as decorative, load bearing elements for porches, entrances, driveway over hangs, etc. Ruggedly constructed, their load-bearing capabilities are certified by an independent testing laboratory.

Painted Columns are electrostatically coated with a baked on high-solids polyester paint, to give a maintenance free, uniform finish. Available in white, almond, and brown.

Primed Columns are treated with a special primer to insure paint bonding to column surface. Columns can be finished with any good exterior paint except lacquer.

Square Aluminum Columns

Assembly
Square Column sections snap together. This should be done on a solid surface such as the floor or a table. the easiest method is to tilt all of the joints into place and snap the last one together. It is best to use a rubber mallet for this. If you use a steel hammer, be sure and use a block of wood on the columns to prevent hammer marking the metal.
