porch columns Columns add visual charm or elegance, depending on style. They can be structural, simply decorative, or both. They can be made from a wide variety of materials, also. For our purposes today, let’s look at the advantages of composite columns.

If you are facing a renovation or restoration involving wood or concrete columns, you should seriously consider using a composite column to cover the existing structure. Of course, depending on the state of deterioration, covering may not be practical. However, in many instances, you can realize substantial savings by using a decorative covering made out of composite materials over the existing structure rather than tearing it down to start over from scratch. With all the options available to you with us, you can have the customized look you want for less.

Composite columns made at Worthington Millwork are created from cast fiberglass, FRP (fiberglass reinforced polymer) fiberglass, polymer stone, and PVC (polyvinyl chloride).
