Fiberglass Columns

Round and Square Fiberglass Columns

Superior Aluminum fiberglass columns play on architectural features and appearances, not unlike those in ancient Greece. Our sturdy bases lead to a graceful taper, creating a stunning aesthetical feature with load-bearing strength. Durable fiberglass construction provides a lifetime of architectural splendor to any project!

Superior’s Fiberglass Columns

Superior offers many styles of fiberglass columns to accommodate every location. Round, fluted or square fiberglass columns are all available based upon your project’s needs.

Fiberglass columns supply the perfect finishing touch to any project. Whether it is a residential or commercial setting, fiberglass columns are versatile and will shine in any space.

Load-bearing strength allows for a beautiful solution to heavy overhangs or awnings. Fiberglass columns are also low-maintenance and will never rot, warp, or split. With columns already primed and ready to be painted, each fiberglass column is ready for you to make it your own!

Standard Finishes – Always Available

For outdoor installations, the columns must be protected with quality exterior paint. An oil based primer is recommended. No special preparation is required, and once painted, the columns will not deteriorate, even under severe long-term weathering.

NOTE: Fiberglass columns are sold unfinished and, thus, must be painted during installation. This enables the ability of each owner to select a color that compliments other features of his or her property.
