Aluminum Columns | Frequently Asked Questions

Are aluminum columns load-bearing?

Yes, most Superior Aluminum columns are load-bearing. Reference the table below for information on maximum load-bearing capabilities for each aluminum column style.

Aluminum Column Maximum Load Bearing Capability

Please note that round wrap-around columns with a greater than 10” diameter are not load-bearing and should not be used in load-bearing applications.

How much weight can an aluminum column hold?

Load-bearing capabilities vary by style and size of the column. For more information on maximum load-bearing capabilities, reference the table below.

Aluminum Column Maximum Load Bearing Capability

Please note that wrap-around columns with a greater than 10” diameter are not load-bearing and should not be used in load-bearing applications.

Can you paint aluminum columns?

All of Superior’s aluminum product lines are available in a mill finish if painting or chemical treatment by a 3rd party is preferred. However, Superior does not recommend that any of its products be installed permanently without adequate surface protection.

How do you clean aluminum porch columns?

For basic cleaning, Superior’s aluminum products can be cleaned with warm, soapy water to remove dirt and debris from the product. For more intense cleaning, a 1:1 vinegar/hot water mix can help clean and shine your metal. Regular cleaning of the product is suggested to keep your aluminum products in good condition and ensure the durability of the product.

Can aluminum columns be set in concrete?

Can you wrap aluminum columns around existing structures?

Aluminum Column Maximum Square Encaseable

Can the aluminum columns be cut down?

Aluminum columns can be cut down to size. A chop saw with a metal/carbide tipped blade is ideal for cutting columns down to size. It is recommended that columns be cut slightly smaller than the height of the install area in order to more easily fit.

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.
