Round Fluted Aluminum Columns

For years, architects have utilized round columns to accentuate historical buildings. However, round fluted columns from Superior Aluminum embrace this traditional look but with a modern touch. Superior columns are manufactured with durable and sustainable aluminum, elevating them above the structures of yesteryear. Aluminum columns are able to withstand harsh weather conditions and keep their impeccable looks to keep you satisfied with your project for years to come.

Both strength and beauty are exemplified with Superior Aluminum’s round fluted columns. Not only can they withstand load-bearing weights thanks to the incredible power of aluminum, but they also provide a durable finish that will not rust, rot, or warp the way other materials might.

In addition, all aluminum round fluted columns contain wrap-around functionality. This allows for easy hiding of dated existing supports, effectively modernizing your space. However, when used in wrap-around applications, special wrap-around caps and bases should be used. It’s worth noting that 6” and 8” round columns can be both load-bearing and wrap-around, while any larger size (10″ and over) only contain the possibility to be either load-bearing or wrap-around.

Most column sizes only require one person to install. Thanks to their lightweight and easily mobile nature, your column installation will be quick and painless, ultimately saving you time and money!

Click here to view Aluminum Column Assembly and Installation Instructions.

What type of paint is used on the aluminum columns?

PPG Duracron paint is used to paint Superior’s aluminum columns and caps and bases. Duracron extrusion coatings meet AAMA 2603 specifications and offer good film integrity, color control, and weather resistance. They must be factory applied to properly cleaned and pretreated aluminum for optimum performance.

What type of primer and paint should be used if painting Mill?

 A multi-purpose primer that is specially designed for metal should be used to prime your column. This information can be found on the “applications” section on the label of the paint.

Please make sure your surface is clean, dry, and dull before applying primer. The surface of the product should be prepared in alignment with the recommendations of the chosen coating manufacturer to ensure proper adhesion. 

Superior does not recommend that any products are installed permanently without adequate surface protection. We encourage you to talk to your local paint store expert or a professional painter to recommend a proper combination based on your particular environment, preferences, and application.

Can I attach railing to aluminum columns?

Yes, your aluminum railing can be attached to your column via Superior Aluminum brackets. Most commonly used are level brackets but vertical or horizontal swivels are available as well. Round Superior Aluminum columns have an option to include an adaptor to create a flat surface. 

Attaching a railing to an aluminum column using level brackets

Please note Superior will generally not provide anchors for attaching these brackets to the column. At this time, premium railing options are not able to attach to columns with this system.
