*What is Satin Anodized?
Anodizing is an electrochemical process that converts the metal surface of aluminum into a decorative, durable, corrosion-resistant, anodic oxide finish. Please note that deviations are common among similar alloys with even greater deviations occurring among different alloys.
Do your finishes adhere to any standards or codes?
Yes, all standard finishes offered by Superior adhere to the provisions set forth by the American Architectural Manufacturer's Association.
What type of paint is used on Superior's standard color options?
Extruded pieces (top/bottom rail, posts, pickets, etc.) are painted with PPG Duracron paint, while castings (brackets, caps, bases, etc.) are powder coated.
What type of Anodized finish is standard?
The standard Satin Anodized finish for all railing is 15M Clear Anodized, Aluminum Association Designation AA-M12-C22-A21, which has a minimum coating thickness of .15mils. Series 500 and 550 have two additional anodized options: A 60M Clear Anodized, Architectural Class 1 finish, with the designation AA-M12-C22-A41, and a 60M Brushed Anodized, Architectural Class 1 finish, with the designation AA-M35-C22-A41, both with minimum coating thicknesses of .7mils. Any Anodized railing outside of the standard 15M Clear Anodized finish may be subject to additional costs.
What coating thicknesses are your standard finishes applied to?
