Coda Architectural offers six standard finishes available on all Opus products – listed here from premium to economical. If you need assistance selecting the proper finish for your application, please contact your local representative. 
Metallized and Powder Coat Finish Coda Architectural

Metallized and Powder Coat Finish

“Metallized–Powder” is a premium coating offering superior corrosion resistance when aesthetics are of the utmost importance. During this process, the base material is cleaned by abrasive blasting, sprayed with molten zinc-aluminum, and coated with an epoxy powder primer. The material is then top coated with a polyester powder coat in any RAL color. The thorough surface preparation and application of zinc-aluminum create a galvanic action that penetrates the surface of the metal and impedes rusting even if the powder and zinc surfaces are compromised. The powder coating provides desired color and additional layers of corrosion resistance. This finish is recommended for outdoor applications and is considered particularly effective near coastal waters. 20-Year Limited Warranty Information

Galvanized and Powder Coat Finish Coda Architectural

Galvanized and Powder Coat Finish

"Galvanized-Powder" is frequently specified for applications where excellent corrosion resistance and the application of color are required. Finished panels are hot dip galvanized to provide a 3-5 mil coating of zinc per ASTM A-123, and then pre-treated to accept an epoxy powder primer. The material is then top coated with a polyester powder coat available in a variety of RAL colors. It should be noted that the initial galvanized coating randomly exhibits rough surface texture that may be accentuated by the application of the finish powder coating. 20-Year Limited Warranty Information

Zinc Plated and Powder Coat Finish Coda Architectural

Zinc Plated and Powder Coat Finish

"Zinc-Powder" finish provides very good corrosion resistance and also provides for the application of color. The primary plated finish provides corrosion resistance by coating the fabricated panel with a smooth, 1-2 mil protective layer of zinc conforming to ASTM B-633. The panels are then chemically cleaned to accept an epoxy powder primer. The material is then top coated with a polyester powder coat available in the complete range of RAL color options. This finish is well suited for interior or inland exterior applications. 10-Year Limited Warranty Information

Powder Coat Primer and Powder Coat Finish Coda Architectural

Powder Coat Primer and Powder Coat Finish

"Powder-Powder" finish is an architectural coating that provides a distinct finished appearance and a moderate level of corrosion resistance. Fabricated panels are first treated by abrasive blasting to remove mill scale and provide a clean, uniform surface. The material is then processed by means of an Iron Phosphate chemical conversion coating. A corrosion resistant epoxy primer coat is then applied and cured by oven-baking. The panel is then coated with a polyester powder finish coat which provides ultraviolet protection and a smooth surface appearance. The finish coating of 5-9 mils overall thickness is an excellent choice for applications where appearance of the surface must meet demanding architectural standards.

Galvanized Finish Coda Architectural

Galvanized Finish

"Galvanized" panels provide substantial corrosion resistance for grille work exposed to atmospheric conditions. Commonly specified as an economical finish for outdoor applications, panels receive a 3-5 mil coating of zinc in accordance with ASTM A-123 after fabrication. It should be noted that hot dip galvanizing is not considered an architectural coating. Galvanized products may randomly exhibit rough texture on the finished surface, dissimilar color characteristics, and will oxidize when exposed to the elements.

Primer Coat Finish Coda Architectural

Primer Coat Finish

"Primer" finished panels provide limited corrosion resistance. This finish involves applying one of a wide variety of primer paint coatings applied to the fabricated panels. Typically specified for applications where on-site finish coatings will be applied, it is important to specify primers that are compatible with the finish coat that will be applied.
